We shoot a lot of AVCHD and I've often had audio conforming problems but I think it is actually worse in the latest version.
I did a four camera shoot of a guest lecturer yesterday. I archived all four cards (entire cord structure) and then wisely put them onto our pristine backup because I know Premiere 'touches' source folders. Then I brought them into Premiere and waited for the clips to conform. After they did **none** of them had any audio (even though the original files were fine). I couldn't find any evidence of conforming files in the STREAM. Where is that information stored?
I decided the easiest thing to do was just to trash the project and start again. This time I imported each card individually, waited for it to conform and checked that the audio was there before I brought in the next card. The first three went in fine; the last one did not. The audio conformed but it sounded garbled, like it decompressed wrong. Also, it stopped about halfway through even though the audio on the card was fine.
Finally, I connected to our pristine archive to retrieve the original, untouched files. That's when I noticed that the files in the local, Working Scratch, folder were about 2 gig bigger than the original files in the Pristine Archive for the cameras that *had* conformed properly. Clearly Adobe is storing something in there somewhere but Apple, in their infinite wisdom, has determined that I don't need to know what is it or where it's been put! Help! If I could find the files I could trash them locally and re-conform. Thank goodness for the Pristine Archive and I *always* put stuff there before I start to edit but... um... other folks don't.
Where does Adobe store the 2 gig of conforming info and why won't Apple let me see it?
