problems with 32 /48 audio
Hello everyone,
So far I always had my footage delivered shot with PAL 48kHz audio.
Now for the first time I’ve got this big project with some 50 different PAL DVcam 32 kHz tapes (but: only two of them are shot on 48 kHz after all).Now there are a few things I’d like to know:
*As I captured some of this 32 kHz footage I got a warning message that my audio might get out of sync (having my capture- and projectsettings set on 48 kHz). How serious is this audio-risk? Will I severely punished when I ignore this? (the 10 minutes I captured looked fine so far).
*When this probability of audio-trouble is high indeed (as I expect it to be), should I put both my capture -and project settings on 32 kHz then?
*If so, how should I do that? In both my capture and project settings so far I could only find 48 kHz presets.
*With 2 tapes shot on 48 KHz-audio and preferring to work with 48 kHz anyway, wouldn’t it be possible to just capture the whole lot with 48 kHz-settings on the Mac and then somehow export the 32 kHz audio-parts (to Sound Track Pro for instance) and thus change them into 48 kHz audio-pieces?
*And if the answer on this last question is positive: how should I do that?I know these are all together a lot of questions, but as I don’t have too much time for this project I can’t permit myself to start experimenting. So I hope you people might have some useful answers or suggestions how to tackle this problem…
Best regards,

A lot of cameras record 2 tracks at 4800 or 4 tracks at 3200 so it sounds like they were set for 4 tracks (but maybe only had inputs on 2 tracks). You should not edit with 3200 khz. FCP will convert these on the fly but it will add a load to your system which will rob performance and it sounds like you have a big project for this to build up in. Just export your audio using QT conversion and set for 4800/16 bit. Then re-import.
