(1) I tried Quicktime Photo-Jpeg with the same result.
(2) I rendered just the audio, and brought it in to the same scene as the Quicktime Photo-Jpeg. Still bad sync.
(3) I just brought the audio in to the original scene and everything lines up. In a couple hours I’ll know whether it keeps sync at render.
Any idea what is causing this? If it’s something I’ve done, I don’t want to do it again!
