Stamped DVD vs DVD-R

When we finish making our DVD and bring it to a duplicator, is it better to have them made as stamped DVDs or DVD-Rs?
Message was edited by: docharris

Better depends how you define better but basically it's "better" to get them replicated (stamped) rather than duplicated (burnt). Better compatibility, can get away with using more bandwidth, support for Region Coding, Copy Protection and so on...

Dual layer DVD -R vs. +R

Hi folks
I've got a stock of DVD+R DL and DVD-R DL. I didn't know you could get -R in DL but I got some good JVC ones and that's what they were. No problems with burning them in Encore CS3, but when I analysed the layer break point in GEAR Pro Mastering, I noticed it was different on the burn of the same project from Encore onto a +R DL disc compared with a -R DL disc. I thought it might be because something had changed between the burns (though I hadn't done anything), so I burned another +R and another -R, and the same thing happened (the two +Rs were the same as each other but different from the two -R's)
Does this matter? Is it normal? I haven't detected a problem. Any thoughts welcome!
Daniel

Nowadays, there is less reason to be concerned, whether one uses -R, or +R, BUT depending on the player used, there could still be residual problems. It was more of a player issue, and newer ones seem less sensitive to the differences. Older players, will possibly still have a problem.
Also, all DVD certified players must play DL discs, BUT none are certified, and required to play ANY burned DVD-9's. Most will, but some just will not, and often the -R vs +R type do not make that much difference. The certification is for commercial, replicated/stamped DVD-9's, like most commercial movies.
I am not familiar with the JVC brand. They might be great, or they might not. Some suppliers just buy the cheapest disc that day, and rebrand them, like Memorex. There are many utilities, and even the free burning utility, ImgBurn, that will tell you what lurks below the JVC logo.
If you are doing these DVD's for yourself, I'd just check with my players. If they are for clients, then a bit of research might be required, as playability may well rest on the exact equipment used. I test on six different players, from bargain basement to esoterics, and have never had any returns, but part of that is probably luck with regards to clients' equipment. Did have one client, whose player would not handle ANY burned DVD-9's, so I just did a multi-disc set for them.
For DVD-9's, I always use Verbatim DL +R's.
Good luck, and wish that there was an iron-clad answer. However with the variations in clients' players, it can be impossible to know, until the discs are tried.

Importing material from dvd

does anyone know how to import video from a dvd for editing?
i have material that isn't on a camcorder, it's contained in dvd and i can't seem to figure out how to import.
thank you!
claire

It would be helpful if you would read the posts you are responding to carefully before responding. I don't appreciate being accused of some illegality. My stated goal was to rip recorded DVDs. MY recorded DVDs. Not commercial copyright protected stamped DVDs. There are no copyright or legal issues involved, which was what half your response indicated. I detailed to the salesperson exactly what I was trying to do, and he stated as a fact the imac would do it, and the help text also indicates it would do it.
I''d agree with you NOW that recorded DVDs are not suitable for further editing--the results are poor based on my experience. But I was also told I'd be able to do this with no loss or even better looking results--not that I believed the latter. I didn't think the results would look like third or fourth generation. If I had been told that the day of purchase, I wouldn't have.
What does "you can import video from a CD or DVD" mean if not, in the vernacular, ripping a DVD? I don't believe imovie indicates anywhere that it ONLY imports DV files, and it will import .mov which I assume it converts to .dv. Imovie does its own conversion in some cases, just not in the case of ripping from a recorded DVD, which it states and was advertised as doing.
Also from imovie help:
"Importing video from a VHS tape or other non-digital format
You can also have your video transferred to digital format by a company that offers digital processing services. You can often choose whether to have your footage transferred to DVD or digital videotape. After your video has been digitally processed, you can import it into iMovie."
What use would it be to have it transfered to DVD if imovie couldn't import it, as this statement indicates you can do?
Seems to me Apple intended at some point in time to provide this ability in imovie and then changed its mind. Not providing the ability restricts my ability to import/copy/rip information I've recorded. That makes no sense.
Note that I am not advocating being able to rip commercial copyright protected stamped DVDs.
Sorry--I don't agree with most of the points in your post. imovie was intended to be a fairly comprehensive all-purpose edit tool from what I can see.
Again, from imovie help:
"Movie HD supports importing a variety of video formats, including DV, widescreen DV, high definition (HDV), MPEG-4 (Simple Profile), and more. You can also capture live video with your iSight (including the built-in iSight on your iMac) and send it directly to iMovie HD.
If you have video or audio clips stored on your computer, you can drag them into an iMovie HD project from your desktop. You can even drag video and audio clips from one iMovie HD project to another!
...Magic iMovie can import your footage from a DV or HDV camcorder via FireWire and assemble it into a movie, complete with a title, transitions between scenes, and even a music track of your choosing."
Nothing there about only importing .dv. And even if imovie was .dv only, how would someone new to macs know that, given all this text and the salesman telling you otherwise! Very confusing!

Dvd problem after yosemite

2010 MBP - played a commercial DVD before update to yosemite - now it refuses to play. Some other DVD's play fine. Disk is pristine - not dirt or scratches. It looks like a stamped DVD. Were there some new restrictions added to the drives in Yosemite?
mgg

Ok, this is weird. I went to my MacPro running maverics - DVD played fine. I make a direct copy to DVD-r. It played fine too. Took both disks to my iMac running maverics - both played there. Went back to MBP, neither would play. I opened system prefs, went to language and region - all looked fine. Closed it, tried original disk - AND IT PLAYED FINE! I tried the DVD-R - and it refused to play. Tried the original and it played fine........
So either this is all and odd coincidence or there is some issue still with some disks in Yosemite. I want to upgrade all my machines to Yosemite but not if I'm going to end up loosing access to some of my content of DVDs.

Disc burned with iDVD will not play in DVD player only on MAC

I used iMovie to create a movie and then shared it with iDVD. I successfully burned the DVD through iDVD but it will not play on my DVD player. It plays fine on the iMac. It is in UDF format. After reading through posts, I saved the file as a disk image and then burned through Disk Utility. This plays fine but I would really rather burn the disc directly from iDVD. Any ideas why the DVD player says "This type of disc cannot be played"?

Media quality affects the burn errors on a disc. Computer players tend to have better error correction (to preserve digital data) - set-top DVD players tend to have poorer error correction since the are designed to play commercial, stamped DVDs with low error rates.

Cross platform DVD burning - Mac/PC/home DVD player

All right, Geniuses, re: cross platform DVD burning, I have read and read and spoken to many people. Out of 6 1/2 billion people, NOBODY can answer this question. Shane Ross probably can't answer it with a straight face.
How, where, why, when, what do I use to burn a DVD - who knows, maybe up to 90 minutes - so that I can play the same DVD on my Mac, your DVD home player, your boss's PC, whether it's Real Player, Windows Media Player, QT, mmrphmm-mmrphmm, or quakiifrafermessendt (w/chrome) format.
I am running Mac G5, dual proc. 2Gig, 3.5 G. RAM, OS 10.3.9, Final Cut Pro HD 4.5 which includes FCP, Compressor Live Type, DVD Studio Pro 3, Cinema Tools.
The editing part is a cinch. Even with my eyes open. I've used Mac since 1978 and shoot broadcast. Oddly, dropped frames, A/V synch, phase shifting, etc are no problems.
Also, I have about 300 shows that I did on VHS, 3/4", Betacam, and DV. I have an A to D converter that works great converting these tapes to digital which I store on my hard drive. What I need to do, let me back up... about a year ago I had to buy a PC because Mac doesn't support Solid Works 3D program. So, there, I said it, I own a PC. And that's why I have a problem. Or more accurately, a quandry. Rather than tie up my Mac, I might as well use the PC to record my videos to, then burn to DVD, then to edit them or run them through DVD Studio Pro on my Mac for authoring, then back to my first problem, How, where, why, when, what do I use to burn a DVD - who knows, maybe up 90 minutes - so that I can play the same DVD on my Mac, your DVD home player, your boss's PC, whether it's Real Player, Windows Media Player, QT, mmrphmm-mmrphmm, or quakiifrafermessendt (w/ultrascuzzyectoplacticdefoid) format.
Of course, I want highest quality. Absolutely, my finished DVDs have to play on PC, Mac and home DVD players. If you've gone this far, someday I might need to put some of this on the web. I like options. It might be delivered as a stream, or a download. Another compression question?
Simple, huh? Is there anything else you need to know? Should I fire up my old wire recorder, or are you going to suggest another 3rd party peripheral? Which would make me wonder, why hasn't Apple addressed this obvious disfunction.
BTW/ I have found Memorex DVDs work best on my system. Any comments?
Regards.

Welcome to the forum!
Time for a reality check: burned DVDs (and even stamped DVDs) are NOT 100% compatible with all DVD-Video reading devices. Period. It just the Nature of the technology and that fact that player and drive manufacturers rush products to market that are not fully in compliance with the DVD-Video standard.
That said, I've had only two individual playback compatibility complaints in the last 6 years with well over 2000 DVD-R discs authored in DVD-SP and burned from my Macs on an external Sony DVD burner. Those two complaints were rectified by burning a DVD+R disc for the clients.
Things I have learned:
· Windows Media Player doesn't play nice with DVD-Video. ULead and other DVD players for the Windows platform do work very well (I have to WinXP systems to test on). PC playback compatibility is dependent on many, many things; the user's video card, RAM, drive type (and condition), processor speed ... the list goes on and on. It's impossible to predict if ANY disc will work in any given PC.
· Memorex is at the very bottom of the list for quality media. Don't get me wrong; they do have a wonderful warranty. If you send back any discs they will replace them with equally poor quality media at no charge. Memorex is simply a marketer - there's no telling what brand or quality of media you're actually getting when you purchase their brand ... but you can be assured it will be cheap.
That said; I'll agree that your workflow seems a bit backward. Authoring to DVD and then editing? Makes no sense. You're losing quite a bit of quality in that process as well as adding unneeded steps. If you must capture the footage with a Windows system and it needs editing, capture then convert to a QT codec that matches your FCP Sequence settings so when you move the files to your Mac for editing, everything actually plays nice.
If your program doesn't need editing and you just want to transfer it to tape, I'd recommend using a stand-alone DVD recorder so you don't have to tie up either computer.

Cd/DVD not burning. Error Code 0x8002006E when burning DVD's

I have a MacBook Black and am trying to burn cd's and dvd's. I have tried multiple brands of DVD and CD and can get the cd's to burn once in a while with a microboards printable cd. When they don't burn I get either an error saying something about not being able to calibrate laser power, or it goes through like it's burning and shows up on the desktop, but when I go to open the disk, there is nothing on it. DVD's never finish, giving me the error code 0x8002006E. It will also not read any DVDr's on the machine. Stamped DVD's (store bought)are fine, but multiple brands of DVDr will not read. All of the burned DVD's I have are personal movies and music videos that I made on the machine. Anyone have any suggestions? Is my superdrive toast?

You can check in system profile and select disc burning to verify what cd/dvds are readable by your superdrive....Also with that error message you can try removing any extra ram chip installed, with that model powerbook it also has onboard ram built into logic...being a disc reading problem id say its the superdrive itself, you can try cleaning the lens with those cleaning discs you buy from electronic stores..Burn disc whilst running on power adaptor and not battery...
just a few things to try might help you

I was using Live Quartz on my MBP to stamp name/date on photos... those photos onto DVDs or USBs for trade magazines to use

the end result was I would have one photo of a cow labeled right next to the same photo unlabeled for a catalogue. I'd burn those photos onto DVDs or USBs for trade magazines to use in their publications. Now all of the sudden I can't do it. Sent an email to LiveQuartz but haven't heard back. What's another simple way I can do this-- one or two steps max? Already tried Preview, but it won't keep the duplicate --- it annotates the original .

Need to import whole video to put on DVD

Everyone, I'm a newbie to iMovie08. Can you help me with this question....I have interviewed my parents in regards to their childhood memories, so as to give these interviews to my siblings for Christmas. I want to import the whole tape from the camcorder to iMovie, and the put a nice menu screen on the video in iDvd. Here's my dilema..
1. I have 3 tapes of video
2. I want to import the whole tape, uninterrupted. I do NOT want to select 200+ seconds of footage (like iMovie breaks up the video) and continue to import, import, and import to the top of the screen.
3. Once I import the whole tape, I want to bring the project over to iDvd to put a nice menu system on the DVD with added photos from iPhoto.
Can someone explain how to import the whole imported video to the top of the screen in iMovie? I hope I have been clear, and THANKS in advance for any help!
p.s. my videos in iPhoto show up to on the bottom left of the project in iMovie. How do I get rid of this completely?

Mpeg Streamclip? Please elaborate.
MPEG Streamclip is a free utility for accessing many of the QT Pro features. While it is not geared to handle multiple audio/video layers like QT Pro, it does include support for multiplexed compression formats (VOB, MEPG2/AC3, MPEG, MPG, Flash, etc.) but does require the proper codecs be installed. Basically, it can utilize all QT components installed on your system and handles many "sequential" content operations better than QT Pro. In the case of merging files, if you "drag 'n drop" a set of selected files to the work window, it is automatically merge them in an alpha-numeric title order. This makes it very easy to merge and then convert VOB title sets which make up a single long video and convert it as a single file for say iPod or TV use. In the same manner, if your DV or HDV (usually now converted to AIC/AIFF) were captured in sequence order from tape and have filenames based on the time stamp or file creation DTG, then your filenames should show up in the finder or navigation list in their playback sequence order. If this is the case, then MPEG Streamclip will automatically open/merge multiple files in their playback sequence also. The "Save As..." option then works much the same as in QT Pro and will allow you to write the sequential data to a single MOV container. (Other containers are only available if, and only if, the content is compatible. E.g., the sequenced data could only be placed in an MP4 container if the data is MPEG4/AAC or H.264/AAC.)
In short, MPEG Streamclip extends some of the capabilities of the QT Structure and, IMHO, is well worth its "free" price tag. In fact, the combination of MPEG Streamclip and QT Pro can handle most of my day to day minor editing needs which do not require a "full-blown" video editor. I would even go so far as to say they have become indispensable.

Resolution to non-playing DVD problem?

It's been a while since I last dropped in here. Fortunately, I haven't had any problems! I was wondering if anyone ever figured out why so many people were having problems with DVD's that would play in their computers but not on DVD players. I may have an idea. I created a DVD project in iDVD 4.0 as a starting template. When I start a new project, I make a copy of the template and then proceed to modify it. Could this be the problem? In other words, could I get around the problem by deleting the template and creating a new template in iDVD 4.0.1 or iDVD 5? I was never able to get a playable DVD with either of these versions. Is there any chance this might work? It would be a bit of a pain to try it since I would have to upgrade the software and then reinstall the old version if there's a problem. But I will give it a try if anyone thinks it might work.
G5 + Powerbook G4 Mac OS X (10.3.8)

Your original message said " I was wondering if anyone ever figured out why so many people were having problems with DVD's that would play in their computers but not on DVD players."
My reply was to that 'observation'.
I've been burning DVDs with the all the iDVD versions almost from the start of DVD burning on the Mac and have been a participant in these forums for all of that period. The necessary second generation 'Superdrives' could write at a maximum of 2x. There were some problems with DVD player compatability (discs would play in a computer drive but not in a stand-alone DVD player) at that time that were resolved by changing the brand of media (not all brands of media have the same rate of burn-errors).
As DVD burners have increased in burn speed (4x, 8x and now 16x) we have seen a major increase in compatability problems on the forum which no longer can always be resolved by changing media brand. Higher speed burns create more burn-errors. Computer drives have the necessary error correction techniques to correct for these errors on playback. Consumer DVD players don't include the necessary error correction techniques to correct for these errors on playback because the stamped discs they are designed to play don't have these errors.
I have observed the problem on several different computers with several
different drives. I never have problems with iDVD 4.0. I am never able to get
a playable disc using 4.0.1 or greater. It also has nothing whatsoever to do
with the media.
If the DVD discs you produce can't be played in computer drives as well as consumer DVD players, yes, you have a different problem. However, that was not addressed in your original statement " I was wondering if anyone ever figured out why so many people were having problems with DVD's that would play in their computers but not on DVD players".

CD-rw/DVD rom drive problem

I am using IBM T43 type 1871 laptop. The problem is with my CD drive. It automatically ejects out every time it wants to.
The same won't happen if I put some CD in the drive. But the CD won't play properly as the system shows the autoplay often and in "my computer " the drive is shown blank for some time and after the autoplay the CD name would be given...
Is it the problem with software or hardware???
Can it be solved if I buy a new DVD drive or use an external??
Now I've removed the drive in order to evade this problem...
Please help me???

Hello,
I am assuming your ThinkPad T43 has a DVD±RW disc drive. Is that correct?
If so, can it read stamped (manufactured) CDs and DVDs? If it can, than the problem may be with reading the recordable CDs or DVDs that you are using. If not, than the problem could be a software one (i.e., related to the operating system) or a hardware one.
If you have a bootable CD or DVD, try configuring the ThinkPad to first boot from the DVD drive, and then attempt to boot from the disc. If that works, than you are likely dealing with a software problem. If the ThinkPad doesn't recognize the disc even at bootup, then the problem is likely with the DVD drive and it will need to be replaced.

Encrypting slides on dvd slide show

Hi - I'm making dvd slide shows of my photography and need to know how to make it so people can't pull the photos off the dvd.. also how to protect the dvd from being copies. Does anyone know how to do this?
thanks
jacquie
www.spectorphotography.com

spec,
sorry in advance for the folllowing tech-bla-bla....
... I'm selling these to clients and can't really sell them marked up photos...
ehm, you're posting in iDVD; iDVD is an encoding, authoring and burning app to create videoDVD, meaning: video, displaying on TV =>interlaced, 640x480, wacky NTSC (apologizes to US citizens...)…
selling PHOTOS that way??
a videoDVD from a photographer as "the map", a portfolio... sure! impressive music, sleezy transitions to some acid-jazz… all that understood & often seen... but SELLING in means of transport this way?
no way.
using tools as Toast allows to you create a video and a data partition on one single dvd-r; you could even "password protect" such a data section (not with Toast, other workflow...)...
soooo.....
stamp a FAT and glowing "this photo belongs to spectorphotography" ... ok, somethin' shorter... and forget the glow.... on every pic in SLIDESHOW; but, please, sell a HiRes version to your clients, ... besides: how shall they "grab" the pics from videoDVD? as screen-grabs??
make watermarks
create a data partition...
sorry for ranting <breathless> ;-))))
hopefully still helpful....?

DVDs look horrible on Apple Cinema Displays

I compress my HD video using Compressor or Adobe Media Encoder, using Compressor's 'Best Quality 90 min' settings. Then burn to a single layer disc through DVD SP. It looks fine on an SD CRT monitor, but when playing back on an Apple 23" Cinema Display, it looks like it's been digitally uprezzed - basically it looks horrible.
However, when purchasing an SD DVD from the store, it plays back beautifully on the Apple displays.
I don't think it's the compression settings. Could it be that I'm burning & duplicatin instead of stamping & replicating? I'm getting lost with this.
Any thoughts?
Thanks!

Final Cut Studio 3

I find the best way is to export as a self-contained movie to a codec such as ProRes (do not use things like HDV) then bring that into Compressor. In Compressor make it a SD m2v as suggested. Though frame controls add time, it is not too painful when using Better (not Best) settings, especially for resizing. The difference between Better and Best is not worth the trade off most of the time in terms of the length of time needed to encode.
Set up virtual clusters to help with time to encode. Also make your own preset and/or make sure to tweak the Apple presets. If using the 90 Minute preset, for example, it is two pass @ 6.2. If you have an hour worth of material, for example, you can go higher. Sometimes the incremental difference may not be seen, but for an hour you can go up more to where it is noticable. YOu could even try a high CBR rate. Take a look at the links below.

1080p footage to DVD or Blu-ray?

I am involved in a feature length documentary film (aprox 1 hour 15 minutes), where we shot all of our footage at 1080p. We used a Canon 6D, Panasonic HMC40 AVCHD cam and some shots with a gopro hero 2.
We will be releasing this on DVD, but this is also my first time ever releasing something on disc in a mass quantity.
What are the best steps to get this process complete and keep the great quality I am seeing on the timeline?
I am using final cut pro, and compressor. After that I am basically lost and not sure on where to go with it.
Any help would be appreciated!
-Anthony

To recap, for a "commercial release" DVD you'll want to get a specialist involved for the authoring of your show. A pro author may also have access to Cinema Craft Encoder sp3 that is used by pretty much all the big DVD releasers to "create the ultimate level of picture quality" you see in the big kids' DVDs.
After the show is authored, there are two routes for production:
A "Duplication" house can burn your DVDs, package them, etc. in relatively small quantities (hundreds to thousands) at surprisingly reasonable rates.
A "Replication" house can manufacture your DVDs, package them, etc. in LARGE quantities more economically. Note the words in bold.
The Duplicator burns the DVD in a way very similar to how you would, that is, use a DVD writer to record data onto a blank DVD.
The Replicator creates a "stamp" referred to as a "Glass Master" to make the shiny inner layer of the DVD and them encapsulates it in plastic to complete the DVD. He literally manufactures the DVD. This process is less expensive for very large quantities and is less susceptible to variations than burning.
The rules for Blu-Ray are a bit trickier, but in reality Blu-ray probably isn't going to catch up with NetFlix as the DVD replacement technology. If your people want to go there, start Googling.
