How to create a dvd with CCE 2.66.01.01 (23.976fps VBR) ?

[Discordian]

I am attempting to get 23.976fps (film) video onto a dvd without the audio giving me synch problems.

My current method:

1) Convert the divx avi to 720x480 aiv with uncompressed audio.

2) Convert the new avi file in CCE 2.66.01.01 using variable bitrate. Audio is converted as STEREO 384k/s

3) Run pulldown.exe on the mpeg.mpv that was produced by CCE.

4) Use TMPGENC's MPEG Tools to multiplex the video and audio together.

5) Burn with a dvd program (dvd workshop).

Problems :

- Audio desynchs
- DVD Workshop appears to re-render the video (may be because of the audio is not AC3

I'm open to any information regaurding this, I'd really like to use CCE variable bitrate since it produces such great quality images per filesize but will use TMPGENC if I have to come to it. You should be able to keep the video at 23.976fps as well and allow it to run. Please explain to me why this is desynching and re-rendering.

Why not try extracting the uncompressed audio and encoding separately, instead of with CCE?

Also, (although unrelated to your problem) you may find it quicker to create an avisynth script from your DivX suitable for input into CCE using FitCD.

The desynchronization is caused either by pulldown or by the multiplexer. Multiplexing is a process you should let DVD workshop handle for you because there are differences in the way DVD MPEG-2 is muxed versus generic MPEG-2.

Also, I gather you're encoding your audio as MPEG-1 layer 2 rather than AC3. The DVD spec is pretty strict about its expectations there: you can have up to 8 audio tracks, but one of those tracks has to be either PCM or AC3 -- MPEG-1 layer 2 audio will either be removed from the stream or treated as a second (alternative) audio track rather than the first.

Thus the re-rendering (?) is probably due to the program needing to generate a new soundtrack to bring the audio to spec, then to remultiplex everything for output.

Try encoding your audio in AC3 format with BeSweet, then feed that plus the video to DVD workshop.

Sounds good. Encoding an AC3 file was going to be today's project. I'll be trying one when the video was 23.976 and then try another after I change the frame rate in virtualdub to 29.976 (which it will be pulldowned into).


I'll reply if I continue to have problems Thank you for the support. I tried to read up on anything I could but couldn't find any 23.976 fps posts.
