I am am using the Avisynth script discussed here: http://3dvision-blog.com/forum/viewtopic.php?f=22&t=344
to convert avi's ripped from 3D Blurays from SBS 3D to Anaglyph. The video converts perfectly, but the audio lags behind by a full 4 secs or so. This has happened consistently with every video that was ripped from a 3D Bluray. And yes, the source avi's audio is in perfect sync. I also tried converting a SBS hockey broadcast I recorded from Satellite and it's audio remained in perfect sync. In VirtualDub, I've tried both no processing and full processing (Lame MP3 192 Kbps) with the same result.
Anyone know why this is happening? Any suggestions for tools that would allow me to re-process the file after the convert and adjust the audio back?
