nightmare audio problem – is AE to blame?
I have a clip of a man delivering a line on camera in my PPro timeline that needed additional compositing in After Effects. I cut in his audio in PPro and then copy/pasted the video into my AE comp. I’ve gotten burned before on dynamic linking, so I prefer to copy/paste, and have done it successfully several times. I do the compositing, render the movie and return to Premiere and import.
This is when the fun really begins…My audio that I had previously cut in of the man talking is gone. Look further, and the audio on the clip is completely messed up (out of sync, totally chopped up, i.e. UNUSABLE). I delete the clip from my project and start over with media browser, re-importing the clip–still messed up the same way.
How does this possibly happen and what can I do to rescue the audio on my master clip?

Dave–While I agree with you, holy crap…talk about going back to the old days…exporting-importing-exporting-importing. But, in this case, I suppose you are right.
I still just can’t understand how a copy/paste could have caused all this madness…

Fair enough, but I had been intentionally vague to begin with because this is some murky water. Here goes:
The clip in question is XDCAM EX HD. It was transferred to my RAID drive without issue. In the clip, I had the on camera talent read the one line he was delivering several times until I was happy with it. When I found the best take, I edited the audio only into an existing PPro timeline. The talent was replacing a line from a different actor. The video in this section was a 3-box composite of on screen graphics and different actors. This is why I copy/pasted the video only from PPro to AE. I had an existing comp and simply needed to replace footage with the new actor and render.
When I copy/pasted, the clip appeared in my AE timeline. But, it was out of view of my :30 comp. So, I stretched out the zoom, found the clip (the “active” part of the AE layer), and drug it back into position in the :30 comp. My theory is that this act of dragging back the video in my AE comp is what messed up my audio. Although, I didn’t even have the audio information in AE–just the video! I then applied effects to the video, a mask, and exported the movie. It was then that I noticed the audio was completely botched. It was out of sync, completely chopped up, parts missing, as I said, unusable. The maddening thing is that this wonderful change had somehow rippled all the way back to my original clip on the RAID drive. And yes, that was my only copy of the clip. In a perfect world, I would have backed it up elsewhere, but that didn’t happen this time.
So, that’s about as much detail as I can provide. As I said before, I’ve copy/pasted countless times from PPro to AE, always without incident. This is a first. That’s the detailed information, now I hope I get an accurate response.

Thanks for the reply…first off, I am on CS6 with Matrox hardware and a robust PC. Should have mentioned that earlier. So, that’s not the issue.
Despite your baseball analogy, I beg to differ. First, I have had FAR better results from my “copy-paste trick” than I EVER had with dynamic link. You yourself have criticized DL before, now you’re defending it? Plus, if you’re saying my problem is long-gop media, how is dynamic link going to solve that? It’s still long-gop media, and I still have to manipulate it in an AE comp.
I don’t understand what you mean by “mixing clips.” This is just straight-ahead footage replacement. In fact, the XDCAM EX footage it replaced was copy/pasted from PPro to AE as well. So, it was totally apples to apples–I just got a different (and disastrous) result this time.

If you’re experiencing garbled audio, my first thought is that the media cache files are to blame. Try deleting the media cache files, and see if the problem persists.

Argghhh–thanks Todd, that was it. I hacked out the .CFA and .PEK files and everything is fine now. Good call!

Would you mind submitting a bug report with as much detail as possible so that we can determine the root cause of this?
