When I cut my *.wav tracks, Vegas always adds an extra frame with a fade at the tail edits. I want to deactivate that option and have given up looking where it's done. Can someone please advise me?

It doesn't add any extra frames. I DOES add a 1ms fade out/in whereever you split it. That CAN be turned off, though.

Turn off: Options - Quickfade Audio Edits.

Sorry, I didn't tell the whole story; when I highlight a clip and right click on the region bar and select Render to New Track, selecting .wav to save to a folder, Vegas creates the clip's portion of the global track, which is what I need to work with in my animation software.

The problem is that when Vegas creates this New Track, it makes it one frame longer at the tail end. Then when I butt these individual tracks in the animation software, my global track grows out of sync. I need to do this to animate lip sync so one frame makes a significant difference.

Would you have any idea where I can tweak this?

Edward, deactivating QuickFade Auto edits did the trick. Thanks!
