PR CS6 and AF100: Audio woe oh-oh.

Long-time FCP user, I've been test-flighting CS6 to move on over soon.

First big bug bite so far. I'm working with AF100 footage 1080p24 w/ LPCM audio from two mics, originals from the heirarchified folder on a local hard drive. It's a large ~1hr long clip.

When I first imported the footage, originally I couldn't get PR to preview any audio. I opened the file in another program (finder) to make sure it was there, and there was indeed audio.

Went back into PR, and mow my audio plays (?). OK, whatever, swell, throw it on the timeline... but now it only comes in as one audio channel that I can't split out into two mono channels. Groan.

That's ok, I figure I can work with that... search for a few seconds, find the option to "normalize audio clip" to -4.5db, and do so...

...that's when it all went really wrong.

PR has now completely messed up the audio track in that project (simple trim edit of one ~1hr clip). Audio is completely and utterly out of sync, almost as if it's been "condensed," or something... just randomly jumps around within the audio track. I can't get it to undo whatever it has done short of trashing the project file and starting over. Thinking it might be a preview problem, I rendered out a small 1min clip from the video... that's wound up completely farked audio-wise.

So... does working with raw camera audio always suck this terribly in CS, or is this new?

Is there a simple and easy way to make it not suck so fiercely?

Hopefully so, because the advertised ability to flawlessly work with raw camera files was a big draw for me to potentially switch.
 
Premiere works flawlessly with AVCHD footage from the AF100

You need to 'Map' your audio at clip level ( depends how you shot and what you want it to do in the timeline) and then you can use Audio FX and the Mixer. CS6 now also has Panner as a fixed effect.

Playback delay was Premiere conforming the Peks and Wavs in your file.
 
My version is most definitely not working flawlessly, and the unsynced, skippy mess it's creating has had plenty of time to consider where all the peaks and waves are.

I have two mono tracks coming in as a single stereo track that cannot be split in the mixer or anywhere else. EDIT: OK, Excellent! I've finally found where to modify this (clip->modify...->audio channels). Audio is still out of sync and skippy. In some clips, there is no audio at all once I modify where the tracks map.

Are there any known conflicts?


edit: as a test, I tried feeding it .mov rewrapped files from Clipwrap. It can't even play back the video on those. What the hey?

Transcoded, trimmed, adjusted, and compressed the hour long project in FCP while waiting for some sort of resolution for CS6's cantakerosity.

meanwhile...

I'm fiddling with some older AF100 footage in CS6. It's all hit or miss with the audio. Sometimes it works and syncs, sometimes it doesn't.

Trying to figure out how to sync audio for multitracks in PR. Doesn't seem to be a way, guess I have to get Plural Eyes for PR.

Maybe FCPX doesn't suck so viciously after all. Or maybe it does.


Dangit.
 
RESOLUTION:

Trashed everything CS6 related. Restarted and disk util'd. Reinstalled, now it seems to be working fine. Guess my install got hosed somehow.

Is there an equivalent of "trash prefs" as done with FCP? Perhaps a similar solution would have worked.
