Thanks for the suggestion, but the problem seems to be specifically related to the export from Avid. As far as I know there is no such thing as “framerate” for sound files, just their frequency (let me know if I’m wrong here). In this case the Avid project I’m working on is 48 kHz, and the raw sound file is 48 kHz as well. In the timeline in Avid everything matches up fine, is the proper length, and plays back at the right speed. It is only when I export (still at 48 kHz), that the audio file is extended by a second, and sync seems to be off.
I gave the sound guy a head pop (not tail, as it’s not customary for our workflow, but maybe I’ll suggest that now), and with that aligned everything throughout the film was in sync (in Avid). The problem pops up when exporting in any format, whether it’s same as source .movs, split video and audio files, or QT references.
Any other suggestions as to how I can fix this issue? Going away on vacation tomorrow and I’d hate to have to drag this with me!
And as always, thanks again for any and all help.
