Highest peak rates for replicated DVD-9 or DVD-5?

Which is the highest peak rate that is most commonly used for replicated discs for all the data streams, and for video? I've tested some well authored popular mass production music dvds with DGIndex and often found video peak rates to go over 8.5 or even 9.
Still quite often it's said for example here http://www.createspace.com/Special/AuthoringNightmares/03/BitsAndBytes.jsp?cfxwasredirect ed=true
that for replicated discs you shouldn't go over 8Mbps rates for video.
I'm having one subtitle track and, 2.0 Dolby Digital and 5.1 Dolby Digital audio tracks in my project, but if the spec says the peak limit for all the assets in DVD-video is around 10Mbps, 9.8Mbps (as I think Neil referred in his alternate bit budgeting guide: http://www.adobeforums.com/webx/.3bb7dccd ) or as 9.6 (as I think Neil referred in: http://www.adobeforums.com/webx/.3bc2e248/0 ) why the video peak rate needs to be that much under what would be possible to be used with subtitles, 2.0 and 5.1 audios? There is like 0.448 Mbps for 5.1audio, 0.256Mbps for 2.0audio, 0.04 Mbps for subtitle, it would leave at least 8.5 Mbps for video? So, it is a little bit confusing what really is the usable DVD peak for replicated DVDs (DVD-5 or DVD-9)? Is it ok in my project to use 8.6Mbps for video if it fits the 9.6Mbps or what ever is the exact scope?

HI David - if going to replication on DLT then you can max out the bit rate if you wish to... however you need to think about whether you need to.
There is a law of diminishing returns here - anything above about 8mbps and I doubt anyone except a well trained 'eye' could see any difference in the quality. All you'll be doing is increasing the file size. Also, it's worth remembering that there are still players which have trouble reading higher rates off a replicated disc (check the DVD FAQ - section 1.41 makes for interesting reading, although not all of these are down to high bit rates, of course).
I tend to encode at various rates with short samples of material and look for the differences. Where I can't see any, I opt for the lower rate. So far this has served me well!
Don't forget that a duplicated disc is using a very different material for the reflective layer and it is far less reflective than a replicated disc. This is largely why you need to keep the duplicated disc bit rate low - players struggle to read the higher bit rates from the less reflective surface and so stutter on playback.
Personally, if you can't see any difference between 7mbps and 9.8mbps I'd advise staying at 7. If there is a difference for your footage then try again with 8mbps, but don't be lulled into a false sense of security over the fact that a replicated disc should be able to have 10.08mbps combined bitrate... the quality of the player is really the issue. Whilst most will, some won't, though all should!

Encode Rates For Replicated DVD

We're about to send off a master DVD-R to replicate a DVD.
I've been told, but can't confirm, that I can go sky high on my video encode rates for replicated DVDs.
That's the opposite of what I've read for duplicating DVDs.
Any of those out there confirm that I can go to 8 or 9 mbps for an under 1 hour DVD with Dolby2 audio?
Or should I stay at 7.0 as I've always done.
thanks

Maximum CBR for replicated DVD-9 ?

I'm compressing audio and video for DVD-9 replication. I wasn't too happy with VBR, so I'd like to use CBR. I have room for the highest bitrate possible, but know there are issues if you go to high. What would be the highest CBR without causing problems?

The max rate is 10.08 Mbps (Page 43 DVD SP 4.1.2 Pdf Manual)though some players fall short of being able to play items approaching the maximums properly (more so with non-replicated disc) with video a max of 9.8 Mbps. Video, audio and subtitle streams count to the max Mbps (Page 44 Pdf )
That being said you should try to limit the rate to the lowest that gives you acceptable results. (That is what I aim for anyway). Usually in general with AC3 audio 8 at CBR should work fairly well.
What were your settings and how long was the running time of the video?

How do you fix error message "data rate for this file is too high for DVD. You must replace this file with one of a lower data rate".

When trying to burn a DVD it will go through the encoding step and at 98% we see the message 'data rate for this file is too high for DVD. You must replace this file with one of a lower data rate". We need help to correct this so we can complete burning to DVD.

What did you export from Premiere?
Did you use the MPEG2-DVD preset... and did you make any changes to the preset?

Best average bit rate & max bit rate for DVDs playing on laptops...

I encode and burn many DVDs for use in regular DVD players....usually in the half hour range and have been encoding with Compressor 3 using these specs:
6.6 average bit rate
7.8 max bit rate
Those same DVDs, which play flawlessly in the DVD players, can occasionally hiccup when played from a laptop. Should I change the max bit rate from 7.8 to 7.7. or lower? Is that the biggest part of the equasion that may affect a laptop's ability to play without choking?
Many thanks,
John

Thanks for all your help, David S, but the point is
that I have tried many different bit rates, from 4.0
to 7.0, and I don't have time to waste all day trying
different bit rates for an 8-minute project.
My main question is: Why would it work fine on all
of my other short projects, including the 8-minute
one, and then when I cut out 20 seconds of that same
project, it starts screwing up!?!
I am going to try trashing my preferences. It is
starting to seem like a corrupt pref file to me.
It turned out to be a corrupt pref file, as I thought. Thanks for your many, many questions, David S.

Low dvd-read rate for COMBO x48

ive bought this MSI 16x combo-drive x48 recently ... when used initially it was set to PIO mode in windows and max data transfer for a dvd wuz 2845 kB/s. sisoft sandra shows the drive as 2X.
Later i changed it to Ultra DMA Mode 2 . now still the max dvd-read rate is (4549 kB/s) .. sisoft sandra now showing this as 5X drive
these measurements were taken with SiSoft Sandra, DVD-Decryptor, v_Strip .. all new versions ..
ive tried several dvd's all original releases, with the same or in most cases lower performance ...
previously when using a 12X Aopen DVD-Drive i used to acheive speeds upto 12,500 kB/sec. while reading dvd's
Now according to your claims im supposed to get a performance of 21,000 kB/sec for DVD ? and im getting only a fraction of that performance ...
my system config is:
P4 2.4 Ghz 533FSB
Gigabyte 8PE667 Ultra 2 Mobo
MSI GeForce FX5600
512MB DDR333 (PC2700) TwinMos
400W Rhycom PSU
80GB Seagate Barracuda 2MB Cache
80GB Western Digital 8MB Cache
Creative Vibra 4D SoundCard
56K Rockwell Modem
MSI x48 COMBO Drive
Windows XP Professional (no service packs) ~2002
WinDVD Platinum 5
Adaptec ASPIi v4.71.2 (for winXp)
what can possily be wrong .. ie. sumthing with the windows that i shud check ? or sumthing with the mobo ide device setting(ATA33 ATA66/100) currently set in bios as Auto
i bought a 16X to give a better performance not to get this degraded performance ...
pls do send a reply soon .. or i mebe forced to think that MSI is only good at mobos !
renjith

Hi:
Try to install the drive as an only secondary MASTER.
In the primary channel, use the fastest HDD as MASTER and the slowest HDD as slave.
Note: USE The primary channel for the Hard Drives (HDD) and the secondary channel solely for the combo drive.
Hope that helps.

Bit Rate for Mixed angle DVD

What bit rate will give an decent quality image if there are 4 video streams (v1-edited video,v2-4 source angles), 1 ac-3 audio stream, 1 mpeg1 audio stream. Three of the video streams are alternate angles that popup for brief ( 1 to 5 minutes ) periods of time in a 1 hour wedding ceremony. I guest the safe bit rate for all streams is around 8.5, the manuals say the max is 10.3 mbps. Can I mix bitrates for video in a mixed-angle track or do they all need to be the same?, is four video tracks just too much info ?
Thanks for all the help !

One last question; if there are four user selectable streams are you adding up the bitrate for all streams or is the total just the stream that's being played plus any audio that gives you your total ?
thanks

Replicated DVD Title Playback Issues (~ 1 out of 20 disks)

Replicated Disc Playback Issues
I recently authored 4x DVD titles using DVD SP 4 in conjunction w/ Compressor 3.0.5. Media was compressed using Compressor “DVD: Best Quality 120 minutes” setting, imported and then built/formatted in DVD SP. The project masters were formatted to Verbatim 4.7 GB DVD-R out of DVD SP without any issue in the log window. I then watched all titles from start to finish on a home set-top player without any playback issues.
The DVD-R disk masters were then shipped to a glass master company, w/o error and verified with an Eclipse system…then back to the Replication house where 1000 copies for each title where made. I watched all Replicated titles upon return, on the 2 different set top DVD players and w/o error.
We have however, been receiving error call-backs on ~ 1 out of 20 DVDs, where people have been reporting video freezes, jittery video in places, etc. I’m new to the authoring world, but believe I was in full technical compliance within DVD SP when building the projects (used APTS tutorial as guide).
Again, the glass mastering company said there were no Eclipse report errors, and the Replication house said the DVDs passed their QT tests as well (Detarius Machine?).
I really need to pinpoint what is causing such a high failure rate in the replicated disks. Is this on my end or the replication process? Did I miss some tech specs in SP that may not pose an issue on some players, but do on others? Shouldn't the QC systems used in the mastering / replication process detect issues with the disks? Any suggestions / guidance would be greatly appreciated.
Many thanks in advance.

Just a 'Toast-it note' guys,
Toast cannot choose your break point except by slim chance, nor properly flag the cell it chooses as the layer break.
A Disc Image does not contain layer break information. There's just information in the Image's UDF/ISO data declaring the full 'extent' of the sectors of data in the Image. Even If you set the layer break point in DVD SP's Format Window when you formatted the Disc Image to hard drive, it will have no effect - Toast, nor any other third party formatting software will have a clue as to your intentions on which cell you'd like designated as the layer break (only the control data in a DDP file set and the control data on a replicated DVD contains layer break info from the DVD project - Control data is not allowed to be written to a DVD Recordable, that area is glossed-over during manufacturing).
Toast only scans the cell address table for the appropriate VOB and chooses a cell closest to the middle of the valid layer break range to split the data stream in two (and uses other algorithms under certain circumstances). But it doesn't flag the cell it chooses as non seamless, or set other layer break cell parameters properly.
Submitting DL Images written by Toast, you will get nailed most of the time by the replicator's Eclipse software for a seamless cell at the layer break - if you're lucky; as more than a few replicators will let that 'warning' message sail right by, and they'll replicate anyway; or they're running a version of Eclipse prior to 4.0, which many are, that doesn't even check for the layer break cell's existence. You could be even luckier, and have a cell command (Marker end jump setting) for the cell prior to the layer break cell Toast chose for the Layer break - that will cause DVD SP to set the following cell as non-seamless. Skinny chance.
If you're unlucky, Toast will choose a proper non seamless LB location in the DVD SP generated files that should never be the layer break location for an abstraction-layer based authoring system generated Image.
Hint: if third party disc formatting software doesn't present you a somewhat cool screen at double-layer writing time, showing you all the available LB cells to choose choose from, complete with the ability to click and preview all of the possible layer break cell canditate's start video, so you can be sure - and properly flag your chosen layer break cell; then it shouldn't be used to write playable DVD+R DL discs. Now, Toast is great for writing DVD+R DL pure data discs, as the requirements for switching layers during the read of ROM data is much less stringent (best to break between files, though).
While there might not seem to be a clear-cut right way to pre-mastering for DVD-Video, for sure, none of the few best/professional workflows allow Toast in the process.
Take care,

The refresh rate for Mac mini 2014 at 3840x2160 using Thunderbolt

Here: http://www.apple.com/mac-mini/specs/
, it says that the refresh rate for resolution 3840x2160 for HDMI is 30 Hz.
I'm wondering if it's the same using Thunderbolt, or more correctly DisplayPort.
Thanks!

MacMagnus wrote:
Ok, thanks!
If I could ask another question regarding this... is 30 Hz poor even for desktop work? Or movies.
I believe the 30Hz is progressive and therefore for movies/video would normally look quite good. However for sports e.g. soccer which has a fast moving object i.e. the ball it would be less good. I have also seen comments suggesting that for computer use it is also less desirable particularly when you are scrolling as this entails affectively the entire screen image 'moving fast'.
This is not based on personal use as I cannot afford a 4K screen yet myself. However for DVDs 24p is considered a to give a good image for movies and this I can confirm from personal experience so 30p should be even better. Obviously 60p is better still but for that you need either a Mac Pro, iMac or MacBook Pro Retina.
It is probably going to depend on what you will be using it for. Perhaps you should consider spending a little more for a MacBook Pro Retina which can do 60 Hz.

Best video format for converting DVD to NAS for widely sharing

Summary: The article shows you with an easy workaround for
copying DVD to NAS for streaming by ripping DVD to NAS friendly video
format on Mac and Windows
I recently purchased a NAS to store all my music/photos etc on. I
can stream stuff to my iPhone/iPad using the NAS software. What I want
to do is rip all my DVDs (over 400) to my NAS, but I’m not sure which
format to do it in, to play nice with my Apple TV2, Xbox 360, iPhone,
iPad etc. I wanna get some advice as to what format to rip in and what
software to use?
Learn some tips from online, I got know that to copy dozens of DVD movies to NAS,
you need to get the content off the DVD disc as a protection-free and
easily readable element for NAS. In this case, at the first place
powerful third-party software for backup DVD to NAS is what you need.
There are many, many DVD ripping tools on the market. I’ve tired a pile of them.
Brorsoft DVD Ripper
is the best one I’ve tried yet. It is capable of ripping DVD to MP4,
AVI, MKV for NAS streaming with no quality loss; it also enables you to
copy DVD main movies for backup onto NAS in .vob format. And what I’ve
learned is that MP4 would be one best target format for it is fully
compatible with nearly all media devices including iPad, iPhone, PS3,
Apple TV, etc. If you are running on Mac OS X, turn to DVD Ripper for Mac. If you haven’t got the software, download it now and let’s start the conversion.
Ripping and copying DVDs to NAS
1. Launch the DVD ripping program for NAS devices . Then
click "Load DVD" to import the DVD files you want to convert. To select
the subtitles you like, simply click Subtitle and select the one you
prefer. P.S. Before start the conversion, you can choose to backup DVD mian movies.
2. Click Format bar and choose your desired format. To store
hundreds of DVD's on NAS, you can rip DVD to .mp4, or .avi, .mkv, etc
compressed format. And click Settings bar, you can adjust the level of
compression to suit the quality you want.
Tip: If you like, you can click “Settings” to change the
video encoder, resolution, frame rate, etc. as you wish. Keep in mind
the file size and video quality is based more on bitrate than resolution
which means bitrate higher results in big file size, and lower visible
quality loss, and vice versa.
3. Press the "Convert" button to start ripping DVD for NAS streaming.
After the conversion, click Open button to find the output files.
Make sure the wireless network connection is accessible among the NAS
and Apple TV, PS3, HD TV or other media players. Then just enjoy the
high quality DVD movies anywhere anytime.

I've always found encoding with Handbrake and choosing the Apple TV2 preset is an excellent place to start and video encoded using that preset will work on my iPhone 4, 4S and iPad 2.
If the files encoded using that preset are too big for one's taste they can always encoded at a lower average bit rate rather than using the default 'Constant Quality' of 20.
Later on I'm sure the Handbrake group will have an AppleTV '3' preset supporting the 1080p format supported by the ATV3 and iPad '3' but using such a preset would not create a file usable on the iPad 2 or the iPhones.

Recording external synth/drum machine - What should the highest peak be?

Hi,
When recording the audio from an external synth/drum machine what should the highest peak be? At the moment I have been recording as loud as possible without clipping but is it better to leave a few DB of headroom if using compressors etc afterwards?
Thanks for the help.

It is good practice with all audio tracking to have it peaking at around -6. I sometimes aim for around -9 when tracking.
make sure you are recording at 24bit. Your peeks can be -18 and you wouldn't suffer too much.

What are the best imovie, mpeg4 settings for making dvds?

What are the best imovie, mpeg4 settings for making dvds?

• iMovie'08 to 11
- Share to Media Browser - AND as Large (or Medium) - HD or other resolutions degrades the final result
iMovie'08 to 11 are not the tools of choise if quality is important as they all degrade the picture by discarding every second line when going from, Event's to Project's and this can not be mended.
iMovie HD6 and FinalCut delivers 100% of what any DVD-Authoring program needs.
• DVD is as standard MAX - intrelaced SD-Video - and can not be any better than this
• iDVD does only care about TIME / Duration as
iDVD 08, 09 & 11 has three levels of qualities. (version 7.0.1, 7,0.4 & 7.1.1) and iDVD 6 has the two last ones
• Professional Quality
(movies + menus up to 120 min.) - BEST (but not always for short movies e.g. up to 45 minutes in total)
• Best Performances
(movies + menus less than 60 min.) - High quality on final DVD (Can be best for short movies)
• High Quality (in iDVD08 or 09) / Best Quality (in iDVD6)
(movies + menus up to 120 min.) - slightly lower quality than above
Menu can take 15 minutes or even more - I use a very simple one with no audio or animation like ”Brushed Metal” in old Themes.
About double on DL DVDs.
• iDVD Does Region = Zero (to be played everywhere)
• Frame rate - DVD can be in two types PAL (25fps) and NTSC (29.97fps)
If Your material is 30fps then keep to NTSC (29.97fps), if 25fps keep to PAL.
One can feed iDVD the other frame rate - BUT RESULTING DVD WILL BE BAD
I use JES_Deinterlacer (free on Internet) to convert all material to the same and final frame rate
• NTSC - US etc
• PAL - EU etc

Going RATE for Final Cut Editor, Apprentice, Assistant, - -FUTURE in FCP?

By trade, I am a composer, and have scored numerous trailers, DVD's, worked in A&R, blaa blaa blaa! (LOL).
Am just getting into FCP Suite (motion, soundtrack, etc)...
Was wondering what the take here (pun intended) is on FCP and it's future! For a while I was seeing lots of FCP editors needed, then it goes back to Avid (especially for television) and was wonder what everyone thinks the future holds for FCP users in the work place!
In addition, just starting out, what are some fair rates compared to a season pro (FCP). I know the standard rate for Avid editors. Just wondering if someone could HASH out a list, from assistant (digitizing, edits, batch processing) to assistant editor/sound designer to FULL BLOWN pro with FCP!
Thanks!

Welcome to the family and try not to take anything personally around here. I've never met you and you don't know me from a jar of Vicks Vapor Rub. Your questions are interesting and we see similar threads a few times every month. Search for "rates" and "making a living using FCP" and "freelance."

Speculating on FCP's future is pointless and this isn't the place to do it anyway, such posts will be pulled. Try creativecow.net, lafcpug.org or any of the hundreds of other FCP-related sites that are not controlled by Apple.(Grammar patrol: It's "its", not "it's")

There are no reliable figures that accurately reflect employment or applications-in-use. They are all anecdotal and they change with seasons and which part of which industry you are attempting to evaluate. Pick a product and get good at it or, as many of the wonks around here, get REALLY good with many popular products.
In addition, just starting out, what are some fair rates compared to a season pro (FCP). I know the standard rate for Avid editors.

You didn't state your location or what you have heard is a "standard rate" for Avid editors: it's the same or it's different. Is there a different rate in your market area for a guy who can play a 12-string guitar than a woman who can play a 4-string bass? Your emphasis in audio and music sets you apart from millions of other video dweebs. Exploit those skills because I don't have any such.

Best settings for older dvd players

anyone have any recommendations on bit rate or other compression settings for older dvd players? everything i produce plays fine on my personal dvd player that actually says dvd-r on the front, but i continuously have problems with clients players having pixel issues of freezing up. i've tried lower bit rates and such but i'd rather not go into all the different angles and just see what you guys say.
I can't be the only person out there that has clients with cheapo players!
thanks in advance.

I don't think you are going to find a single solution to this problem. Just about every DVD player is going to have problems with some brands or types of recordable DVDs. Some things to consider or try:
1.) Educate your customers about potential DVD media problems. Potentially tricky since not everyone will freely admit or accept that such problems exist.
2.) Burn the DVD at the lowest possible rate (burn at 1X rather than 4X, etc.).
3.) Try a different brand of DVD-R.
4.) In special cases consider using DVD-RW rather than DVD-R (some older players will actually work better with DVD-RW).
5.) Consider using the best possible DVD recorder (I'd recommend Plextor drives mated with Roxio's Toast software).
6.) Use a commercial DVD mastering service (only practical if you want to duplicate several hundred discs -- too costly for small runs).

How to Acquire Data at High Rate for Several Seconds?

Hello Everybody,
I am using a PCI 5152 with 64Megs of memory per channel. I am also using Labview 7.1 in WinXP. My PC is a Quad Processor Computer with 2GB of Ram.
I need to acquire data for several seconds as follows: I am triggering at 1ms and for each trigger I want to save the first 200us of data at the highest possible rate (more than 200MHz).
I have developed the code attached but I keep getting the error -1074116198 (buffer overwrite). Any ideas or suggestions are welcome
Thank you very much in advance.

Hi Jhon,
Could you please provide a screenshot of the front panel for your VI when you run the program and receive the error (I want to know what each value is set to). Are you able to run the program without error when you decrease the record length and/or sample rate? Additionally, what are the values of the Records Fetched and Records Acquired indicators when you receive the error? Can you please provide a screenshot of the actual error message you are receiving as well? Finally, I am curious to know why you are taking your min record length value and dividing it by the period (reciprocal of min sample rate)? I look forward to hearing back from you soon and reproducing the issue you are seeing.
Cheers!
