DLTs and layer break questions
Hi guys. I have 2 questions on layer break points and DLT tapes. About a month ago, I completed a DL DVD project that was sent out to a replicator on DLT tapes for replication. I had burned DVD copies (from the software not from the DLTs) for testing and had no problem with those. Then I burned the DLTs and had no problem burning those. The tapes went off to the replicator and a few days later I got an e-mail telling me that the replicator received this error - "seamless playback flag not set correctly at layer break". They said they could fix the problem for $175 a layer or $350. So to expidite the problem, the client went ahead and had them fix the problem.
Now here are my 2 questions...
1. It took me some time to find a usuable break point because the disk is so full, there is only a limited area where a valid break point could go. But after I found it, I had no problems with the disks I burned or burning the DLTs. Why would this error then pop up in the replication step if it wasn't an issue before?
2. Now I have a new e-mail from the client saying that when he watches the one-off from the replicator, on certain DVD players there is a jitter during one of the videos that wasn't there on the original test disks I sent him. My theory is that the replicator moved the layer break point to fix the previous problem and that now he is seeing the jitter at the new layer break. (I originally had the break point set in an area of black so any pause wouldn't be noticable). Does this sound like a good theory? And getting back to the question 1 again, why would the replicator have a problem with my DLTs if the test disks I burned worked fine?
Thanks for any advice you can give me.

Cmerillo,
The only thing the replicator could do to your Image is properly flag the existing layer break cell as non seamless, if that indeed was what triggered the Eclipse rule. We'd have to see, as other phenomina can cause that error.
If the replicator created another cell in your VOB for the layer break, that's a no no, and they should know better.
Only the authoring system can safely place the layer break cell, due to the fact that if you place a layer break cell after the fact, without the authoring system's knowledge, you'll have video/audio and/or subtitle packs for the previous cell duration (now split), sitting on the second layer 1, the authoring system 'thought' was on the first layer (due to it's proper multiplexing routines). This will cause decoding glitches across the layer break on many players.
So, you might find out what the heck they did; which they should have consulted you on before doing anything. But it sounds like they added a cell for the layer break to your existing VOB.
The only way to get an approximation of what's on the DLT, is to restore the DLT's Image to hard drive and burn a disc from that. Each multiplex and formatting is potentially different (Long story on this fact, but lots of surprises can await if no testing is done on that DDP Image).
Sorry you're having issues. Let me know if you need some help with this one. Or, for sure, please keep us posted as this unfortunate situation progresses.
Take care,

does the layer break work like this:
layer 1: vts1, vts2, vts3, vts4
layer 2: vts5, vts6, vts7
Or is it completely irregular? I am just trying to understand how I should structure my vts content. In my mind, I am trying to organize 4.7gb worth of data within the first groupings of VTS.. and then imagining my 2nd layer begins after that-- though I am questioning this since the only track option I have for the layerbreak option is the same regardless of what order things are in...
-pThe only DVDSP project element that can be identified as a layer break is a marker. You can let DVDSP automatically pick one for you, or you can pick one yourself. The disc will pause when it hits the break, so there's an advantage to choosing an apppropriate place, or hiding it somwhere.
Some things to help you choose the break point:
Layer0 (the first layer) must be bigger than layer1 (the second layer). This means the break must come after the halfway point in the total media on the disc. The fuller the disc is, the smaller the range of possible positions for the break.
If you can put the break between two VTSes, either put it on the first marker of the first track for layer1, or do what I do and put a dummy track on the disc. I'll put a second or two of black - you can use a pict file - into a track and put the layer break in there. Nothing points to it, and so no one will ever see it, it is just there to contain the layer break.
If you need to put the break in the middle of your movie, it'll need to be an I-frame in the encode. If I know this will be the case, I'll usually scan through the area where I expect it to fall and drop in several encoding or chapter markers on potential break points in Final Cut before I encode.
Look for a frame without motion and as little audio as possible. I have also noticed that some players seem to display the frame just before the marker as the freeze frame while switching layers, so if you want to see the freeze on the incoming shot, rather than the ougoing shot of a cut, you might want to move your marker forward one frame. -
How to manually create layer breaking point for DVD9
Hello, I was wondering if someone could please tell me how I would go about to manually set the layer break point for a DVD9 project that I burned onto 2 DLT tapes. The total size of the DVD is 6.3GB.
I had used the "automatic" setting for burning the DLTs and sent them to a replicator. They came back saying that the layer 0 tape did not allow enough headroom for their Ripguard protection.
I've always used the automatic setting and this is the first time I am asked to manually set it. SO now I need to figure out how I can put a certain amount of data on one DLT tape and the rest on the other DLT.
I am a beginner at this so any help would be greatly appreciated.
Thank you!Hi Eric,
Unfortunately the information you have regarding RipGuard and the ability to copy RipGuard protected discs is a little outdated.
Can RipGuard be broken? Yes, anything can be broken into, including the DoD Website by 14 yr old chinese students... but that doesn't mean there isn't value in protecting the DVD.
Also, RipGuard is regularly updated, just like Antivirus software, so while older versions of RipGuard can be broken more easily, the latest versions of RipGuard are significantly more difficult to circumvent by existing software.
But again, the point isn't to create the unbreakable 'holy grail' DVD copy protection, but rather to protect something of value.
When you leave your house in the morning, do you close your front door and lock it? Of course you do, but why? So no one will break in. But do you think locking up your house is really going to stop someone from going around to the side of the house and busting out a window if they really want to get in? Of course it wont. If someone wants to break into your house, they will find a way.
Same thing with DVDs. You lock your house because it provides a method of protection, a barrier to make it more difficult and to keep honest people honest. That's what RipGuard, or any copy protection software does.
So the question isn't why would you protect your DVD, but rather why wouldn't you? In most cases if you prevent just a few illegal copies of your DVD from being ripped, it has already more than paid for itself. -
Setting a Layer Break for GEAR Pro Mastering Edition with EncoreDVD & IFOEdit
Setting Layer Breaks Manually for Encore/GEAR Projects
Although we can write straight to a DVD+R DL disc directly out of EncoreDVD 2.0 and we can also create our Master DLT tapes directly out of EncoreDVD 2.0 also, there are times when these options simply are not sufficient.
For example - we wish to Verify the successful writing of a DLT Tape, or we wish to create a QC disc for our clients in DVD-R DL format.
Either way, the "option" of using a +R DL disc is often unacceptable.
Another very good reason for +R DL discs to be NFG is that they are NOT DVD-Video format, and as such tend to expect the layers 0 and 1 to be of equal size.
Yet another reason could simply be we are using EncoreDVD 1.01, which does not support direct writing of any DL discs at all.
The solution is to use GEAR Pro Mastering Edition to create your DLT or DVD-R DL disc directly from your Encore project instead.
And here's how you do it.
You are going to need copies of both GEAR Pro Mastering Edition, EncoreDVD (any version) and finally a copy of the freeware application IFOEdit http://www.ifoedit.com/. Additionally, we will also need the GEAR Layer Break Calcuulator, provided for free on their excellent support site at http://www.gearsoftware.com/support/documentation/layerbreakcalculator.xls
Now we are ready - lets look at how it is all done. Don't be put off by what looks like a lot of math here either - this gets easier every time you do it and all it takes is a little common sense and practise.
The best way to proceed is to use EncoreDVD to build your project to a folder. This will not make any Layer Break settings at all, and will allow us to create a new DL Project in GEAR and also allows GR+EAR to build the UDF/ISO structure for us.
So once we have written our tested and checked project to a folder, the next step is to close out of EncoreDVD and launch GPME. By the way - if you're not certain that you need the expense of GPME for a one-off project you can simply download their 30 day trial version and use this as it is 100% fully functional in every way - there are no limitations at all.
When GEAR loads, select to create a new DVD-Video project and be certain you tick the DVD9 box in this screen too. Another window will appear now asking you to locate the folder where the Video_TS files are stored. Point this at the Video_TS folder and GEAR will create a basic DVD9 project for you.
Next we need to load up the Excel Spreadsheet with the Layer Break Calculator we downloaded earlier. I always use a different machine for this as I don't have Office installed and any open source application that can read an XLS file will do the job. If you don't have one, I recommend either OpenOffice or Star Office to do this. There are a lot of helpful calculators in XLS mode, and you won't regret it. Just try to keep all this stuff well clear of your authoring system though. But I am rambling, and I'm sorry. Back to buiness.
Once we have loaded up our Layer Break Calculator, we need to enter in some numbers.
Back over in GPME, where we have our shiny new DVD9 project sat there waiting for instructions, there is a file structure on the lower left hand side of the project screen. Att the top of the list we should see something very much like "VOLUME (projectname) (DVD-Video ISO/UDF)"
Right-click on this, and select "Properties". A screen will appear with all sorts of numbers in it, and we ignore the lot of them except for the "Total Volume Size in Sectors" - which we need to write down, nip across the room to our spreadsheet, and type the number in right at the top where it says "Total Volume (project) Size"
Another set of (probably) meaningless numbers appears - and the 2 we are interested in here are the ones where it says "RULES" and specifically "Layer Break Point must be Greater than .....
And Less than.....
Write these 2 numbers down, and hop smartly back across to where we have our GEAR project open on our authoring machine. Or simply minimize the spreadsheet if we are doing all this on the same system.
We now need to click on the folder marked "Video_TS" in the bottom left of the GEAR screen, and on the lower right we need to click once on the bar in the middle above all the VOB files marked "start sector" to arrange all the files in the sequence they will be on the disc. This makes finding our VTS file so much easier.
Somewhere in that list there will be a file that has that range of numbers in it. If we are really lucky, there will be more than one, which means that one of these will soon become our Layer Break.
When we have identified the correct file, take a note of it's name - it will be VTS_01_4.VOB or something with a similar structure name wise.
Next, we need to write down and enter into the Layer Break Calculator the start sector number of the VTS_xx_1.VOB file that holds our values.
I will try to explain why. If our Sector range is to be found in the example we gave earlier, say VTS_01_4.VOB, we need to note the start sector of the file VTS_01_1.VOB. This is because all these VTS_xx_x.VOB files are all extensions of the same file. They are just in handy blocks so that the Computer can keep track of them without breaking any rules about file sizes. Anyway, we write down the Start Sector of the file VTS_xx_1.VOB where xx is the file where the Layer Break range is to be found.
Just to try & make the concept clear, if the range were found in the file VTS_05_5.VOB, our start sector we need to write down is VTS_05_1.VOB
Enter this into the Calculator/Spreadsheet in the place where it says "Chosen Video Object VTS_xx_1.VOB Start Sector.
Now this will tell us exactly where we need to look next, and tell us we now need to hunt for a cell start sector between a range of sectors.
It might be something like "1,148,678 and 2,051,052" sectors.
This is where IFOEdit comes in.
Launch IFOEdit - and you may as well go back to GEAR, and close the project - but not the application. Go to the "File" menu, and from the drop dow select "Delete GEAR Project" and delete the one we just created, as we will need to change it anyway. Why you will find out later on.
From IFOEdit, you will see 2 halves of a screen. Down the bottom left there is an "Open" button. Click on this and locate the Video_TS folder, and specifically the file VTS_xx_1.IFO, where xx is the file we know from earlier the Layer Break will be placed.
Immediately your head will start to ache, your eyes will glaze over & your brain will wave a little white flag, as some serious mathematics suddenly appears (Well, that's what happened to me the first time. I was too fascinated to be confused - sheer bewilderment is perhaps the best expression. And I still don't know what most of it is for.
The one we are interested in can be found in the upper half, and is called "VTS_PGCITI".
Click on this, and a lot of little others will appear immediately below it.
You will see VTS_PGC_1 and so on until you run out of blocks.
The odds are high our layer break will be in the longest file - but this does not always hold true, so we start at the top & work our way rapidly down. What we are looking for is twofold.
1 - A Cell Start Sector within our range defined earlier.
2 - A cell Start Sector flagged as "NON Seamless playback.
If we can fill both these criteria, we have our layer break.
Write this number down, and enter it into our spreadsheet - and close down IFOEdit as we are done with it for today.
Back in the Spreadsheet we are almost done. Once we enter this number in, it will helpfully calculate exactly where in our Virtual image from earlier that sector lies, and will check to see if it is divisible by 16. Don't worry for now why, just know that it has to do this.
The chances are high it will not be, so the spreadsheet will tell you how many sectors the whole image has to be shifted forwards by, and what the new Cell Start Sector is in this revised image. This is automatic, and you get 2 figures.
1 - Offset. This number will be between 0 and 15.
2 - Layer Break Sector.
Time to go back to GEAR, and in our "Options" drop-down menu we will have another one called "Preferences". In this, we need to tell GEAR to ask us for the start sector to be entered for each file.
Now we create our project again - but this time GEAR will ask us for the start sector of VIDEO_TS_IFO, and the figure 640 will be highlighted.
Add our offset figure we were given earlier to this so if our offset was 11, enter in 651.
GEAR will do all the rest automatically for you.
One more job to do now.
Go Back to "Options/Preferences", and under DVD we need to tell GEAR we are changing the Layer Break. Click on the "Change" button, and use the up/down arrows to arrive at our newly discovered Layer Break Value.
Save the project - we're done. And write down that offset & Layer Break whatever you do.
You can now write to DVD-R DL, DLT tapes (and if you right-click on your DLT drive in the lower "Devices" screen, and choose "Properties", you can tell GEAR to verify the tape after writing too. It will write both layers first, then verify each one.
There is, however, a minor "GOTCHA" in GPME when writing DLT tapes.
It is allowed to set the IDENT.TXT file to be included on the DLT tape by means of a tick box. However, as this file is not actually required for replication in DVD-Video, but only in DVD-ROM - GEAR will not include the file
i even if the box is ticked
but it
i does
add a pointer to the file in the DDPID file instead. The upshot of this is that a DLT tape where IDENT.TXT has been selected to be included will be
i rejected by the factory as unusable.
This is because when they try to verify the DDP image on the tape it will fail as IDENT.TXT is NOT on the tape.
You must ensure this box is NEVER TICKED - I fell for this one recently, and had to rework 7 DLT tapes.
There is yet another way to get a DL project to the factory if you do not have a DLT machine, and do not have access to DL discs in the correct format.
Write the DDP images to 2 single layer discs instead!
This requires the use of GEAR Pro Mastering Edition again, and is incredibly easy to do.
What you need to do here is follow the original guides in the FAQ sections for setting the Layer Break manually, but instead of writing the project to DLT tapes or to DVD-R DL/DVD+R DL media, what we do next is write the project to a DDP file on the HDD instead.
This will result in 2 folders appearing - Layer 0 and Layer 1.
Each of these has the necessary information for the replication plant to manufacture the discs - all we need to do is get them onto 2 discs instead of 2 DLT tapes.
This is simplicity itself.
Launch your burning application.
Create a new DVD-ROM project.
Name it (Project)_Layer_1
Broswe to the 2 folders with the DDP files in them, and add the contents in this exact order
DDPID
CONTROL.DAT
IMAGE.DAT
(Checksum.txt - optional)
(Log file - optional)
Burn the disc.
Repeat for Layer 1.
That is all there is to it.
What will happen at the factory is the Eclipse verification system will look for the DDPID file at the root level of the disc. If it cannot find it, it will assume it is dealing with a standard DVD-ROM disc instead, but if it is there it will know what is going on, load the files, and ask for Layer 1 after it has finished in the normal manner.
I hope this helps out - if not, please post in the main forums, and I'll try to help out.Hi Ryan,
Yes, you'll only get the LB sector number when you format with one of the "tape images" (go with DDP 2.0). And unfortunately, Gear doesn't allow transfer of DDP or CMF Images to DLT.
Gear is working on a version that will incorporate DVD-9 making within the program.
Meanwhile, If you go with the instructions on their site to create a DVD-9, be sure to add: "correct VTS sectors" in the VIDEO_TS folder with IFOEdit, and set the region info in the VMGM_MAT to "0"; and be sure to flag all instances of a cell properly for the layer break, in the case they reside in any Stories that span the Layers.
But if I may; It's highly recommended that you hire out tests on the resulting DDP image to make sure the layer break did indeed fall where you expected, and that there are no other issues (Same goes with any DDP image destined for replication, created by any other program).
Or better yet, consider hiring someone to premaster for you (I wonder who? , who also includes navigation proofing, spec compliance testing (MEI and sometimes with a player bank) and verifying the finished Image (EclipseSuite); all for one low fixed price, i.e. no charge in the event a resubmission to me is required (pre consultation, also included, nips lots of common mistakes in the buds). This insures that only a bullet-proof Image is finally sent in to the replicator.
There I go with commercials again! But for sure, Gear's current DVD-9 method is not for the faint of head; and premastering in general, is not the innocuous activity it appears to be. Real trouble eventually awaits (unless measures are taken), due to the nature of the critter.
Take care,

Layer break solution for a single 2 hour continuous timeline (DVD-9 DL) in GEAR?
Having a single 2 hour continuous timeline in Encore project. When the project is exported there isn't any non-seamless cells in the layer break window that GEAR is providing. According to DVD specification the layer break should be set to a non-seamless cell. So, how to properly set the layer break when there is no legal layer break cells in the layer break window?
The only solution I know is using PGCEDit to change one cell's type to non-seamless and use this as the layer break cell. In PGCEDit you double click the VTST and see all the cells. Pick one cell (that exists in the layer break window calculated in GEAR LB spreadsheet) and de-tick the "seamless joint" checkbox of the cell you want to use as the LB cell, then choose OK to exit the VTST panel. Save your DVD (remember to have at the Options -> Output -> leave 32k of space, selected when saving). Now you have a dvd standard non-seamless cell for the layer break.
Couple of questions rise:
Is this 100% legal and risk free to change the cell type like this or is there something more to it? Do you also have to uncheck from the cell's "Flag type panel" in PGCEdit the "seamless angle change" and the rest of the flags in order for this to work the way fully intended?
Has anybody done this in a situation like this for a commercial title?
Is there any other way to achieve a legal LB for a one long continuous timeline without non-seamless cells existing?
PS. I have also a one cell just outside the layer break window that GEAR is providing me, alraedy marked as a non-seamless cell. I can't use this cell in GEAR though as a layer break cell as this cell is outside the layer break window. Any ideas why Encore has outputted this cell as non-seamless? maybe it comes from the Automatic layer break setting in the Encore's BUILD panel when you output a folder? Even though when you export as a Folder, it shouldn't set actual layer break to it, but maybe it still sets the intended LB cell's type to non-seamless? Is there any way to get GEAR to respect the layer break that Encore has automatically set if you export your project as image from Encore (and I guess when the project is build as an image, the layer break actually should be set there, right?).Try to convert the audio to AC3 file, that should be a quick fix.
Do you have motion menus or any other elements? 2.96 and 928 should bring you in fine (take a look here http://dvdstepbystep.com/faqs_2.php - which way are the numbers - the larger or smaller when using Get Info?) -
I have a .img file I would like to burn to a DL disc. I did so with Disc Utility and it came out fine except at the layer break, where I lose a few seconds of footage (right at a vital point in the film, no less).
I tried opening the file in iDVD6 but it won't let me, and when I try to import the file to iDVD, it says "Unsupported File Type: Unknown Format."
This is my first Mac, and I've had it all of two weeks, so I'm just learning the ins and outs. I've searched in the forums, but haven't found anything to address my question, so if someone could explain how to open the file in iDVD or how to burn using Disc Utility and fix the layer break issue, I would greatly appreciate it.

Encore CS4 has been giving me issues with manually setting the layer break on dual-layer disks. I'd like to hear from everyone out there who is using CS4 to create DL disks with a manual layer break. Does Encore always ask where to set the break when you tell it to?
Hi Jim.
Cannot remember back to version 1, and never did a DL disc in 1.5 that I can remember, but certainly CS2/3/4 for me have never worked properly with Layer Break dialogues. One of the problems I faced that cost me a lot of lost face was when I was using version 2 on a live concert DVD for Porcupine Tree.
I worked all the data rates locations of chapter points out manually, and knew that according to the manuals, Encore should use a chapter point if one is available within the range allowed. There were 3 in that range, so I left it as automatic.
Burned a DVD+R DL disc, and on my Denon players the break is often not even noticeable. Client approved, and we created the DLT tapes.
Back came the test moulds, and to my horror the break was not on a chapter point at all but on a GOP header around 31 seconds after the chapter it was supposed to be placed on automatically. Drat. Call the factory, tell them not to press, and I will deliver a new set of tapes in 6 hours time.
Power up DLT, Boot Encore, set break point manually. (Incidentally, Version 2 was the only version that has ever worked on manual mode for me. CS4/CS3 never do. I click on manual, and suddenly nothing happens) and set it to Chapter 17 (it could also have gone on 16 or 18 according to the dialogue)
Rewrite DLT tapes, deliver to factory, get next test mould - same freaking problem. The darn break has not moved.
Turned out that when we analyzed the tapes, the original break point had been left. A long call to Adobe support ended up with the "best guess" option that once the break poiint had been set, it remained set. The Abstraction Layer had a nasty bug and would not allow subsequent editing, it seemed.
Since then, all DL discs have been exported from Encore with no break point set at all to straight folders, and pre mastered in GEAR Pro Mastering Edition.
PGCEdit takes a bit of getting used to, but my lord, what power is there under the hood! It is seriously well worth learning as you can change so much without needing to recompile from Encore. You can even edit the entire CLUT maps change button highlighting, edit links, set cells to seamless/non seamless, alter userops, all manner of wonderful things. ALso - After Effects definitely requires rocket science. It's beyond me. My partner thinks it is great she loves it though.
AFAIK ( and I will check) -R DL is now supported in CS4, not sure about CS3.
Anyway - all that aside, how are you doing Jim? Long time no talk to

My DSP 4.1.0 will not allow me to set layer break manualy. Have tried to open earlier projects and the same happends there (I was allowed earlier). It even does not show me the disc size!
Mac OS X (10.4.7)Hi Ole,
Welcome to the discussions forum.
In Outline - highlight the Disc Icon(your title) right at the top of all the list - go down to Inspector - click tab/Disc Volume/Break Point - and assign the track that you want the break point to be recognised.
I assume you will be burning the disc yourself - and not sending the project to a replication house? There is a reason for this question - but ignore it if you are burning the disc.
Hope this helps you,

Layer Break Issues with Encore 2.0
I have a dual-layer project that is doing something strange:
When authoring the project I left the layer break to automatic. After writing an image for review, a few people complained that the layer break was in a bad location and some players were having trouble with it (high motion area of the film). So I re-wrote an image and this time told it to do the layer break manually. I chose a specific time to place the layer break.
These new DVDs now act as if there are 2 layer breaks in the video. The new location where I told it to place the layer break has a slight pause in playback, like the player is switching layers, but then at the original layer break location playback is pausing just like it did before.
I have checked the video file and it is fine and has no glitches in it. Is it possible there are two layers switches in the project (it doesn't make sense to me, but I have to ask).
Thanks for any help anyone can provide.
MikeMike.
What is happening here does seem to be a bug to me too.
There is - happily - a solution to the problem. A couple of them, actually. What one to use is going to depend on the final output your project needs to be.
You must reset the break yourself as well as remove the existing one. The problem is that once Encore sets an automatic break, this will remain set - whatever you may reset later on down the line. So you're going to need a copy of PGCEdit. This is freeware, and is available from http://download.videohelp.com/r0lZ/pgcedit/
To use this, export from Encore as a DVD Folder - and then load this folder into PGCEdit. Follow the internal instructions for changing/Previewing the Layer Break. It will allow you to remove the incorrect one & reset the new one. You'll need to use the CFH file though as I cannot remember off the top of my head the precise instructions. It's not too hard to do though. PGCEdit will automatically back up your unmodified files too - just in case. Then to create your replication masters, simply reload the modified folder into Encore "Build DVD" dialogue & write the DLT tapes.
If you're going to burn discs instead of replicating them, you can use the much simpler IMGBurn method.
Download this wonderful piece of freeware, and set it up so that the layer break is "Calculate Optimal".
Load your Encore folder. It will ask you where you want the break, and it will also allow you to preview the exact cell location too.
Set to where you want, burn the disc. -
Encore CS3 Error: Disc requires a layer break
Hi,
So I'm trying to build a DVD with DVD Video and ROM content (3.92GB for DVD video and 4.61GB for ROM content) on a dual layer DVD. When preparing the disc layout encore stops and comes up with a warning: DualLayer - This disc requires a layer break.
I've set Encore to make the layer break automatically, and changing it to manual doesn't make any difference... can you help?? I've tried exporting the project to disc, image and folder but it makes no difference!!!
TimYou have a mixture of problems at play here, and whilst this may seem like a pain in the rear, there is a way out for you.
Problem #1 is that Encore cannot set a layer break in the ROM content, as it cannot hook into it and therefore has no way of knowing what it contains.
Problem #2 is that when creating DVD9 discs, there are 2 ways to master them - OTP (Opposite Track Path) and PTP (Parallel Track Path).
All DVD Writers are incapable of writing in PTP mode. This has caused me problems on more occasions than you can possibly know. It's a real PITA.
You can however
i replicate
to PTP mode.
Why is this the case? Well, because DVD is usually used for DVD-Video, and the Layer Break needs to be as unobtrusive as possible - so the disc mastering uses OTP so that for Layer 0, the laser starts at the middle of the disc, travels to the outside, refocusses to Layer 1 and then travels back towards the middle again. The idea is to minimize the time taken to refocus, giving if anything just a small pause at worst, should the break point need to be placed in the middle of a film (Do not confuse this with "Seamless" layer break in apps like IMGBurn, as that ONLY applies to Multiple Angle discs. NEVER add a "seamless" flag on a single angle film)
Trouble with OTP is that you cannot have more information on Layer 1 than on Layer 0 - for obvious reasons.
The solution is PTP - and this has to be done in a PreMastering application. GEAR Pro Mastering Edition is one for PC, and DVD AfterEdit is one for Mac. The masters cannot be burned. They need to be written to DLT tapes.
One possible workaround is to tell Encore to create a Folder with just your DVD-Video material. Do not - at this point - add the ROM content.
Launch IMGBurn (freeware/Donationware, www.imgburn.com)
Go into BUILD mode.
Make sure it is set to "Calculate Optimal" for Layer Breaks.
Add your Video_TS folder.
Add your ROM folder.
Hit "Write" - it will tell you it cannot find a suitable location for a Layer Break to spec, and ask you if you want to proceed anyway.
Tell it "YES" and it will make your disc.
Where the layer break will be is anybody's guess, but it will load your Video_TS and try to split the data equally between the layers. It should put it between files.
It's your only shot at getting a written disc - this will not be suitable for replication unless you master it in PTP mode though.
Good Luck. -
Layer break on DVD9 error. HELP!
I´ve compiled a DVD9 project but I cant play it out as DDP files to my hard drive (no DLT). I get the error message- "no suitable marker found for layer break....". I set everything to automatic and have burned a DVD9 that works. Is it possible that my total data is too big at 7,982.312 Gig? Any help is desperately appreciated!
Help! Deadline!
Thanks
GlennYou might try manually setting the break point. That's usually a good practice anyway because you can be assured it will happen in a good place where the stutter won't be as obvious.

ALV: How do I suppress repeating values and page breaks on printed output?
Good day, everyone!
First, I've done a LOT of searching trying to find the answer to my question, but I'm not finding an answer. If this has already been answered and you can point me to a URL, I would appreciate it.
Here's my issue: I have a rather simple ALV report. It has the columns of Person ID, Personnel Number, For Period, In Period, and Amount. I sort by Person ID and Personnel Number, and if the value repeats on the next line of the report, I want to suppress it (make it blank).
I thought the answer was in the following code, where I set the GROUP attribute to asterisk:
CLEAR sortcat_ln.
sortcat_ln-spos = '1'.
sortcat_ln-fieldname = 'PERSONID_EXT'.
sortcat_ln-up = c_true.
sortcat_ln-group = '*'.
APPEND sortcat_ln TO sortcat.
CLEAR sortcat_ln.
sortcat_ln-spos = '2'.
sortcat_ln-fieldname = 'PERNR'.
sortcat_ln-up = c_true.
sortcat_ln-group = '*'.
APPEND sortcat_ln TO sortcat.
It looks PERFECT on the screen -- the values are suppressed if they repeat, and everything appears together on one screen. However, when I print the report, two things happen: 1) The values repeat on each row, even if they are the same, and 2) I get a page break after each Person ID / Personnel Number combination.
I now realize that I can't use the GROUP attribute. Is there some other way in ALV to blank these repeating values and keep all the rows together on one page, rather than page breaking after each value change?
Thanks!
DaveHi
Same requirement i had before, when i try to print preview. the output of the grid display is in grouping is ok, but when i print preview or print it doesnt cater the grouping and page breaks, so what i did i modify the internal table use in alv , after hitting the print preview/print with the format desired by the user. you can do that in user-command. see code below
FORM user_command USING r_ucomm TYPE syucomm
rs_selfield TYPE slis_selfield.
DATA lt_sort TYPE lvc_t_sort.
CASE r_ucomm.
WHEN '&RNT_PREV' OR '&RNT'.
t_final_x[] = t_final[].
PERFORM clear_redundant.
PERFORM set_sort_criteria USING lt_sort.
WHEN '&F03' OR '&PRINT_BACK_PREVIEW'.
t_final[] = t_final_x[].
WHEN OTHERS.
ENDCASE.
ENDFORM. "user_command
hope it helps -
Hi! Hoping someone might be able to help with an odd problem. I haven't found anything in the forums or the web that match my symptoms.
I've been using Encore CS6 (v6.0.1.013) on a MacBook retina over the past year to successfully create a number of single sided DVDs with menus, chapters, and all that. I usually make a copy of a previous DVD project, and then replace video assets with the new files and transcodes, move and rename chapter markers, and rework the menus in Photoshop. I then will build ISO images for both DVD and Blu-Ray (both single-sided), and use those to burn many copies of each DVD for clients.
This week, while developing one of these projects, when trying to build a DVD ISO image that looked like it would fit on a 4.7 GB DVD, I received the "layer break" message ("The chosen layer break does not satisfy dual layer requirements. To fix this, either set a new layer break manually, or choose to set layer break automatically.") because (I'm guessing) the material was too long for the 4.7 GB DVD (the Build screen now shows about 5GB of material are in the project). This is the first time I've seen that message - usually Encore just tells me the material is too big for the DVD.
I re-transcoded the material down to well under 4.7 GB (about 3.9 GB), reverted and replaced the transcoded files, and now the DVD build screen shows that there are about 700MB free on a 4.7 GB DVD. But I still have not been able to build any version of the DVD (image, folder, disc), without getting the "layer break" message. I also now get this same layer break message when trying to "Preview from Here" any menu, killing my ability to preview the DVD menus in Encore.
Just to see what would happen, I chose an 8.4GB Dual Layer DVD, and chose "manual" instead of "automatic" for the layer break selection, but never got the layer break selection dialog box, just the "layer break" error message.
I typically build both DVD and Blu-Ray images from the same material in the same project. I use different transcoding settings for each, and I have been able to build a Blu-Ray ISO without this "layer break" error on the Blu-Ray build (which is about 24.5GB when built). And as I mentioned before, this is the first project on which I've even seen this layer break message.
Any suggestions would be greatly appreciated! I'd rather not recreate the project from scratch, but I'm worried that I may have to.
Thanks
JonThe total project being small enough may mean you have one layer that is too big. Both layers have to be smaller than half the disk, right?
Be sure you "run as administrator" for dual layer projects.
Encore may set the layer break correctly if it finds a good place, but there are numerous complaints about it being unreliable.
Build to a folder (no layer break is set), then use ImgBurn to build and ask to be prompted for layer break. ImgBurn is also unreliable under some circumstances.
The most frequent problems appear to be when there is no good location for a break. Do a search for "layer break imgburn" and you will see a variety of strategies.

Adding a RAID card to help speed up export (and other drive question) in Premiere Pro CC
First of all, I have read Tweakers Page exporting section because that is where my primary concern is. First my questions, then background and my current and proposed configurations:
Question 1: Will adding a hardware RAID controller, such as an LSI MegaRAID remove enough burden from the CPU managing parity on my software RAID 5 that the CPU will jump for joy and export faster?
Question 2: If true to above, then compare thoughts on adding more smaller SSDs for either a one volume RAID 0 or smaller two volume RAID 0 to complement existing HDD RAID 5. That is, I'm thinking of buying four Samsung 850 Pro 128 GB SSDs to put in a four disk volume to handle everything (media/projects, media cache, previews, exports), or split it up into two volumes of two disks each and split the duties, or keep the four disk volume idea and put the previews & exports on my HDD RAID 5 array.
The 850's are rated at SEQ read/write: 550/470 MB/s thus I could get around 2000/1500 MB/s read write in a four disk RAID 0 or 1/2 that if I split into two volumes to minimize volumes from reading/writing at the same time, if that really matters with these SSDs?
The Tweaker's page made a few comments. One is splitting duties among different disks, rather than a large efficient RAID may actually slow things down. Since the SSDs are much faster than a single HDD, I'm thinking that is no longer accurate, thus I'm leaning toward the Four disk configuration putting OS & Programs on C drive, Media & Projects on D (HDD RAID 5), Pagefile & Media Cache on SSD (2-disk RAID 0) and Previews &Exports on 2nd SSD RAID 0 (or combine the two RAID 0's and their duties).
Just trying to get a perspective here, since I haven't purchased anything yet. Any experience/stories, I would appreciate.
My current drive configuration:
My D drive is software RAID 5 consisting of four 1 TB Western Digital RE4 (RED) 7200 RPM HDDs with a CrystalDiskMark SEQ Read/Write of 339/252 MB/s.
The C drive is SSD 500 GB (Samsung 840 (not Pro) and does 531/330 MB/s. My OS, Program Files and Page File are on C, and data/media files/project, etc all are on the RAID drive.
Problem:
Current setup allows for smooth editing, only the exporting seems slow, often taking between two and two and a half times the video length to export. Thus a 10 minute video takes 20-30 minutes to export. 15 minute video can take 30-40 minutes to export. The first 10% of the two-pass export takes under a minute (seems fast), but it gets slower where the final 10 or 20% can hang for many minutes like my system is running out of steam. So where is the waste?
I have enabled hardware acceleration (did the GPU hack since my GPU isn't listed) and it may spike at 25% usage a few times and eat up 600 MB of VRAM (I have 2 GB of VRAM), otherwise it is idle the whole export. The CPU may spike at 50% but it doesn't seem overly busy either.
Our timeline is simple with two video streams and two audio streams (a little music and mostly voice) with simple transitions (jump cuts or cross dissolves). We sometimes fast color correct, so that might use the GPU? Also, since we film in 1080 60P and export 1080 29.97 frames/sec, I think that is scaling and uses the GPU. I know without the GPU, it does take a lot longer. I have ruled out buying a faster GPU since it doesn't appear to be breaking a sweat. I just need to know if my system is bottlenecked at the hard drive level because I'm using software RAID and my disks are slow and will hardware RAID significantly reduce the CPU load so it can export faster.
Our files are not huge in nature. Most our clips are several MBs each. Total project files are between 5 GBs and 10 GBs for each video with Windows Media File export being 500 MB to 1.2 GB on average. We shoot using Panasonic camcorders so the original files are AVCHD, I believe (.MTS files?).
Considerations:
1. I'm thinking of buying (and future proofing) an LSI Logic MegaRAID 9361-8i that is 12Gb/s SAS and SATA (because some current SSDs can exceed the 6Gb/s standard).
2. I'm not replacing my current RAID 5 HDDs because not in my budget to upgrade to 6 or more large SSDs. These drives are more important to me for temporary storage because I remove the files once backed up. I don't mind a few inexpensive smaller SSDs if they can make a significant difference for editing and exporting.
I can only guess my HDD RAID is slow but the CPU is burdened with parity. I would imagine running RAID 10 would not help much.
My setup:
my setup:
CPU - i7-3930K CPU @4.5 GHz
RAM - G.SKILL Ripjaws Z Series 32GB (4 x 8GB) DDR3 2133 @2000
Motherboard - ASUS P9X79 WS LGA 2011
GPU - Gigabyte GeForce GTX 660 OC 2GB (performed the compatibility list hack to enable hardware acceleration).
C drive - 500 GB Samsung 840 SSD (Windows 7 Pro 64 bit and programs).
D drive - four 1 TB WD RE4 Enterprise HDDs 7200 RPMs in software RAID 5
Case - Cooler Master HAF X

Power Supply - Corsair Pro Series AX 850 Watt 80 Plus Gold
Optical Drive - Pioneer BDR - 208DBK

Eric........software RAID 5 off the motherboard ??????......NOT a good idea, from what I have read here on this forum from experts like Harm Millard and others. They have mentioned a LARGE overhead on the CPU doing this....causing sub-par performance. RAID 0 off the motherboard will NOT do this, however.....RAID 0 would provide optimum speed, but, with the risk of total data loss if ANY drive fails. You may wish to reconfigure your RAID to be RAID 0...BUT...you would need to DILIGENTLY back up its entire volume onto perhaps a quality 4TB drive very frequently.
A lot depends on the nature of your current and FUTURE codecs you plan to edit. You may not want to sink a lot of money into an older setup that may have trouble with more demanding future codecs. For now, in the 1080p realm, your rig should be OK....the read/write performance on your CURRENT RAID 5 setup is not great, and a definite drag on the performance. The rest of your components appear to be fine.....the Samsung SSD, though not ideal, is OK.....it's write speed is WAY lower than the Pro model,but, the drive is used mainly for reading operations. Since you have Windows 7 Pro, and NOT Windows 8.......you CAN put the entire windows page file onto the RAID 0 you might create.....this will take that frequent read/write load OFF the SSD. Read the "tweakers Page" to see how to best TUNE your machine. To use your current setup most efficiently, without investing much money, you would :a. create the RAID 0 off the motherboard, ( putting all media and project files on it ) b. install a quality 7200rpm 4TB HDD to serve as a BACKUP of the RAID array. Then, install a Crucial M550 256GB or larger SSD, ( close in performance to Samsung 850 Pro...much cheaper), to put all previews, cache , and media cache files on....AND to use as " global performance cache" for After Effects...if you use that program. Exporting can be done to ANOTHER Crucial M550 for best speed...or, just to the either the FIRST Crucial or, the 4TB drive. Your current GPU will accelerate exports on any video containing scaling and any GPU accelerated effects. Your CPU is STILL important in SERVING the data to and from the GPU AND for decoding and encoding non-GPU handled video....your high CPU clock speed helps performance there ! You may want to check out possibly overclocking your video card, using MSI Afterburner.or, similar free program. Increasing the "memory clock speed" can RAISE performance and cut export times on GPU effects loaded timelines,or, scaling operations. On my laptop, I export 25% faster doing this. With my NEW i7 4700 HQ laptop, I export in the range of your CURRENT machine....about 2 to 3 times the length of the original video. PROPERLY SET UP...your desktop machine should BLOW THIS AWAY !!
Visit the PPBM7 website and test your current setup to possibly identify current bottlenecks,or, performance issues. THEN, RE-TEST it again, after making improvements to your machine to see how it does. Be aware that new codecs are coming (H.265 and HEVC,etc.) which may demand more computer horsepower to edit, as they are even MORE compressed and engineered for "streaming" high quality at a lower bandwidth on the internet. The new Haswell E...with its quad-channel memory, 8 core option, large number of PCI gen. 3 lanes, goes farther in being prepared for 4K and more. Testing by Eric Bowen has shown the newer PPro versions provide MUCH better processing of 4K than older versions. -
Hi,
In desperate straits here. I've created a dual layer project and set a break point via the disc inspector drop down menu. Now I need to change the break point but DVDSP won't execute the change. I've deleted the VTS build folders as Apple recommended but that has no effect. This is the second project- after running into the same problem prior, the only solution that I could find was port all of my assets and start a new project. I was able to set the break point once but now I'm back to where I was the first time. Any help that anyone could give would be tremendously appreciated. Thanks in advance.Thanks for the reply...unfortunately that isn't the problem. I haven't tested my theory yet, but I now have an idea what happened and if correct, I would consider it a bug. A big bug.
When setting my break point, I did so via the disc inspector drop down menu and went to the track of choice and selected "track" as my breakpoint rather than selecting a mark of any sort. Once formatted and built, it seemed to have locked the breakpoint in place and would not even let me delete the track in an effort to clear it. After porting all of the items (via item descriptions) into a new project I created the breakpoint using a marker in the track. Viola, it now behaves as it should.
I will be testing my theory as soon as I have a free moment...meanwhile, my layer breaks will come from a marker specifically created for it.
Thanks again.
