AE Export drifting sync in FCP
Ok guys. What am I doing wrong? This is the first time this has happened, so I’m a bit frustrated. I edited HDV footage in FCP and XML’d via Automatic Duck into After Effects. In AE I color timed and added motion graphics. I exported from AE with these parameters: 29.97, Animation, 48.0KHz, 16 bit. Imported this into FCP and placed into a new 29.97 timeline. I copied and pasted the audio from the original FCP edit timeline into the new timeline with the AE animation export, and the audio drifts out of sync. I’ve done this literally, thousands of times without any sync issues. What am I doing wrong this time?
Thanks guys!

Thanks, Dave. I’ve never had this problem before, never had problems with AE 9 and long-gop HDV footage. All timelines in both programs match, and I haven’t compressed the audio any more than what was done already in camera. I have a strange suspicion that it’s somewhere in the AE export settings, but again, I haven’t changed anything since I last did this. My last option is to use the exported audio from AE, but the thought makes me cringe.

It sounds like a framerate issue, but your workflow sounds pretty solid. I would say the best starting point would be to make sure that not only your framerate but the actual duration of your footage matches in AE and FCP.
If the duration is off then there’s a framerate issue we may have overlooked.
You could also do a frame check and go to the exact same time code at a late point in the video in FCP and AE and make sure that you are in fact looking at the same exact frame.
These aren’t solutions but hopefully they’ll help flush out the problem.

Darby… I compared specific points on corresponding timelines in AE and FCP, and they all matched to the frame. This further indicates that it has something to do with AE’s export — right? Dave, I really don’t want to accept that after using AE 9 for a year that it decides to dump on me now. We’ve had a beautiful relationship thus far. On the other hand, the incredible issues I had with Premiere CS3 years ago, nothing would surprise me. Also, importing HDV as APR422 seems like such an incredible waste of space.

Ok… I think I had an Automatic Duck failure. I tried exporting again, and received this error: internal verification failure, sorry! {RenderXMP hit item missed by PreRenderXMP}.
I re-XML’d from FCP via Duck, and no problems. Whew! Thanks for your suggestions guys, I hope this post helps anyone else with similar issues in the future.

Does AE 10 have issues with HDV?

After Effects CS5 has greatly improved handling of MPEG-based formats, including HDV (which is basically MPEG-2).
