avi frame rate 23.975 and audio sync

[at_mix]

I have a file divx5.0 w/ frame rate of 23.975 ( instead of 23.976)

and audio divx(wma). When i convert i get an increasing audio

sync.

Do i have to change the frame rate? or just matching the

frame rate and sound in virtualdub ( direct stream copy or full

processing )?


Thanks

First try a "Quick" method:

1. Open your divx file in Virtual Dub or VirtualDubMod

2. Select "Video" > "Framerate"

3. Select the radio button for "Change so Video and Audio Durations Match" click OK

4. Go to "File" > "Save as AVI" (F7)

It didn't work. I still have an increased audio sync ( sound is

earlier in the end, it starts ok ) when i convert to dvd.

Isn't it because of the strange frame rate 23.975 and the divx(wma) audio.

Do i have to change frame rate? What can i do?

Based on the audio format used, I'd speculate that it was actually interleaved with the video every 500 milleseconds, rather than every 1 frame.

1) Load the file into the standard VirtualDub

2) Set "Video" to "Direct Stream Copy"

3) From the "Audio" dropdown menu, select "Interleaving" - and set "Interleave audio every" to 1 frame

4) From the "Audio" dropdown menu, select "Full Processing Mode" - Select "Compression" and choose the 96Kbps the MPEG Layer 3 (.MP3), 44,100Hz sampling rate

5) Save with a new filename
