Mix is bouncing out with an extra frame

[TheSoundshaper]

Whenever our avid editor imports my mixes they are an extra frame too long. We can't figure out why this keeps happening. Any thoughts? Upgraded to Ultimate and still have the same issue.

Try bouncing two versions of the same mix, one with Enforce Compatibility on and another with it off. See if there's any difference.

Also make sure your file is EXACTLY the length of the video file, and not even one sample longer. Media Composer doesn't like files that don't start and end exactly on a frame boundary, so it may be doing some kind of padding on import.
