NTSC Film Avi to Mpeg2 issues

[ultrazero]

I've done this before, but can't seem to get it to work now.

I have an AVI (DIVX codec) which runs at 23.98 fps or NTSC film. I'd like to burn it to a DVD. However, when I convert it to an mpeg 2 file with ffmpegx, the audio because extra slow. Video converts fine but the audio is slowed down to a crawl and in turn becomes twice the length of the video. I'm using DVDSP 3 to author the dvd.

here's my workflow:

1) convert the avi using ffmpeg encoder (tried mpeg2enc as well with same result)

2) demux the resulting mpg file with bbdemux (just checked it now and the mpeg doesn't even have audio)

3) add pulldown flags with ffmpegx to the m2v file

what am I doing wrong?

Also, is there a way to avoid using bbdemux? Its a great app, but it seems weird that ffmpegx can't add pulldown flags to its own output.



btw, this is legit, I'm trying to burn Dark Side of the Moon + Wizard of Oz. I own both. Obviously sync is a MAIN concern here.

Try to enable "Decode with Quicktime".

hmmm. Whenever I use decode with quicktime, the ffmpegx progress app doesn't progress. It opens and the candy cane starts moving, but it never shows a progress report. However, it does do something because the output files get bigger and bigger.

In that case everything is fine. Wait for the "Finished" message and check the resulting files.

Might this have something to do with the audio sample rate? Before encoding try setting the audio out rate to match that of the audio in rate, for example 48000. This has worked in the past for myself personally when I experienced the issue you noted.
