Creating 24bit DVD help please..

Hi all, I've been doing audio for years, but recently wanted to do audio DVD's in 24bit to share. I can easily create a true DVD-A using discwelder chrome. But am having a heck of a time creating a 24 bit DVD. I have Premiere Pro CS3 and Nero. I created my timeline and chapters in PP. I imported the 48/24 files and used black as my video layer, and everything is fine in there. Every time it exports to Encore it transcodes it to 16 bit. I exported as an AVI file in 24 bit and using Nero to burn it, but that won't recognize it. I even tried to copy the true DVD-A (which works perfectly) back onto my HD and rename the audio_TS files and AOB files to VOB files. Still no luck. Am I overthinking this and missing something very simple?
Advice would be greatly appreciated.
TIA

The DVD Video standard allows for 24 bit audio (at either 48 or 96 kHz). I'm not sure of the authoring capabilities of various programs for creating music-only DVD video discs.

Personally, I think 24 bit files should be shared as FLAC files - they can then be written to DVD by the downloader or played directly from the computer (which is what I do).

What would the audio bitrate be at that level?

Re: Creating 24bit DVD help please..

Yeah, you don't have to produce a DVD-A with MLP audio, a Video DVD would be sufficient. Linear PCM audio goes up to 24/96 with 8 channels at a bitrate of 6144 kB/s But I guess you are aiming at 24/48 DTS.

I wonder why there aren't more people sharing audio as a video DVD. A downside is of course that the cheap DVD players people have down-convert the audio quality anyway. But sure lot's of people aren't aware of this and grab the DVD anyway just for the 24 Bit audio sticker.

Just as a reminder, for audio only Video DVDs you still need a video stream, otherwise the DVD is not valid. Use highly compressed stills or a ultra low bitrate black screen. A AC3 stream also has to be present ... and let's not forget that in blind test hardly anybody notices the difference.

Re: Creating 24bit DVD help please..

My original intenet is to find a way to share a 48/24 show that other than beeing muxed not to be altered in any way i.e. Dolby Digital or DTS encoding. I was able to achieve this, but only by doing true DVD-A. Th problem with that is that not many people have DVD-A players. I even checked at work where we use Sonic Scenarist. I talked to one of the compressionists who told me that straight 48/24 cannot be written to a standard DVD.

My question now would be, what is the best way to share a 48/24 show:
1. 48/24 flac files (so the user can decide what to do with the files)
2. DVD-A (keep in mind, it would be inteneted for the relative masses)
3. DVD with 48/16 and vob.'s

Last part.. What I would like to upload is Steely Dan Grand Prairie, Tx. 2008-08-21. The taper (Falconidave) Sent me his masterfiles to master the show. All work was done on the 96/24 masters, then down sampled. The results are pretty good, and believe that it's a major upgrade to what is out there now original thread http://www.thetradersden.org/forums/...ghlight=steely
I know this has been discussed in many forms and at many different times about remasters, and the lack of quality in many of them. I want to assure you guys, I know what I'm doing.
44.1 sample here: http://www.4shared.com/dir/5493427/6...0/sharing.html

I know I got off topic, but I guess opinions on both would be cool.

My vote is for 48/24 FLAC files, giving the downloader complete flexibility (including the option to downsample to 44.1/16 if they want).

I have a DVD-A player, but since moving my music to my PC I don't use it anymore.

I can tell you that you can create a DVD-Video disc using 24bit/48k or 24bit/96k 2-Channel LPCM audio. I have created DVD Videos with both of these audio formats using DVD Lab PRO 2.0. The bitrate for 24/48 is 2304 kb/s and it doubles to 4608 kb/s for 24/96. I don't really want to give advice on how to share it, but it works perfectly with that program. Like I said I have done this with video footage on the DVD, but the program also has the option to create audio-only DVD-Video discs.

Re: Creating 24bit DVD help please..

I've been using this program (other than discwelder) for DVD audio.

Its cleverly titled: Audio DVD Creator

96/24 audio & allows for static menus (pics, info file, etc).. kinda cool.

great stuff for those 3 and 4 CD-R disc shows in single DVD seamless format.

of course playback is limited to wherever you have a dvd player integrated to your sound system.

Re: Creating 24bit DVD help please..

I already pointed out the 16/48 AC3 + 24/48 PCM option. That of course means that your video bitrate is going down. Remember that theoretically the bitrate read-out of stand-alone players is limited to 8 MBit/s for DVD-Rs.

Option 2: Produce the usual 16/48 AC3 audio DVD and put the FLAC files in the DVD_ROM part.

Option 3: Usual DVD + extra DVD with files.
