Vegas 6 renders out of sync
When I render a long program to a new .avi file, the rendered file is out of sync by around 10-13 frames. (It varies.) How can I prevent this from happening?

Out of sync with what?

The sound is out of sync with the picture in the rendered file

I recently had the same problem when converting some captured MPEG2 files to Sony MP4 (for use with a PSP). My immediate thought was that my computer wasn’t up to the task, but that doesn’t strike me as the answer since the audio went out of sync during a conversion, not a capture.
Anyone have any ideas?

I talked to Gary Kleiner on the phone this morning, and he has the same idea that you do, Brett: he thinks it’s most likely a hardware problem.

If the audio is in synch before you render, it is highly unlikely that it is a hardware problem that makes it out of synch since the “only” hardware involved in rendering is the CPU.
You say you render to avi, which isn’t really saying much since avi can be just about anything. What codec are you using for video, what codec are you using for sound?

Terje, I’m using the “Render as…” choice in the File menu in Vegas, and then choosing .avi as the type of file to render the program.

Okay, but what template are you using? Default? Maybe that’s your problem. Try doing the same thing but go to the template box below the AVI and choose NTSC-DV (or PAL is you’re using PAL), or any of the other templates besides the default uncompressed.

Just some background info. There is no such thing as AVI video. AVI is a wrapper format, not a video or audio format. AVI can contain data encoded with many types of codecs. When you encode to AVI you also chose the codec to use. For video editing you should typically use DV-AVI matching your source, for publication you may use DiVX or similar.

Is it out of sync for the entire clip or does it get progressively worse, that is, starts in sync but gets out by the end?

I’ve had it go both ways. One project started out in sync, then got worse to about 10 frames out. Another was consistently about 13 frames out.
