Audio codec making my sound go out of sync!

Postby kearlywi » Thu Apr 10, 2003 1:19 am

Since I downloaded the virtual dub filter packs "AdvancedAVS1_00" and
"AMVapp1_02b" my audio files have been compressing incorrectly. That is as the movie progresses the audio gets gradually more and more out of sync. By the episodes end (25 mins) my sound is off by over 3 seconds. Ive tried using most audio compressors and each has the same problem. I realize that there is probably a 0% chance that the video filters are affecting my audio syncing, but it was the last change I made b4 I started noticing problems. The only other change I made was I slightly changed the bitrate to 700 from 756 (again this shouldn't make a difference).

While I'm at it, what sound compressor does everyone use in virtual dub?

In Virtual Dub I went to:

video/frame rate/source rate adjustment/"change so audio and video durations match (29.97)" (this is not the default setting)

This fixed my synch problem.

don't use 29.97, use 24.

You should be using LAME MP3 and encoding at the same frame rate you exported from Premiere with.
