Divx doctor messing up my audio

[ruggerjvd]

I am converting SVCD ready mpg2's to AVI's so I can edit them, using ffmpeg. I am using the mpeg4 codec with mencoder. I am encoding the audio at 128 kb/s and 44100 khz. The resulting avi works great.

I then am processing the file with divx doctor, as I think I read here that that is required to edit and save as a mov. However, the resulting .mov from Divx doctor has the audio out of sync.


Any suggestions on how to correct?

thanks

A few thoughts:
-your avi should be editable in Quicktime Pro without converting to .mov
OR
-if you are editing in FCP or iMovie why not covert to DV?
-mpeg2Works comes with a tool for this.
-mpg2decX and Quictime Pro can also do this,
but for your audio, you'll need to demux, then export to .aiff
-FCP can bring in your DV video and .AIFF audio separately for editing
-or you use add or add scaled (if necessary) in QT Pro to put in the audio.
the resulting .mov should be editable and in sync.

- if you are going to re-encode to mpeg 2 and burn to dvd, you might as well encode your audio with 48 khz sampling frequency.

good luck.

The problem is that the audio is not QT Compatible.
Using ffmpegx to create your MPEG-4 [.AVI] option is good,
(and yes this will fix many of the problematic MPEG 2 files,
and still get decent quality to edit with as far as video is concerned.),
but on your audio, select "Passthrough" as your audio option.
Often times, ffmpegx when re-encoding the audio, especially
at below 192kbps, and 48khz quality, WILL THROW IT OUT OF SYNC.

Better to go with Pass through Audio, and encode the video to
the MPEG-4[AVI] option. Then, you can use Divx Doctor II to
make your movie file, so that everything is QT Compatible,
and you then can do quick edits in QT and save out your file
to DVDSP2 or iDVD.
