Audio not working on HDV files...

*I just realized there was a Mac section which might better help my question out, if someone could possibly move it over there I'd be grateful...

Hi all,

So I'm working on a project that was shot on a Sony Z1U with a shotgun microphone plugged into one channel and two lav mics on another. The footage (1080i) was all captured onto a hard drive by the director and he gave me the hard drive to start taking a look at the footage.

For some reason, I'll open one of the files in QT and I'll hear audio on some takes but not on others. The audio comes in at the beginning of one specific take for example and then will cut out when the next one starts so it seems to be an in-camera problem or change somehow considering I can still hear the audio in other parts of the file and it doesn't just cut out at random parts but with each take...

At first I thought they had shot those sequences without sound somehow - but, we brought this very same hard drive to my roommate's computer, plugged it in (he has an PPC iMac 2.0 GHz, and the audio worked perfectly fine throughout the ENTIRE file on his computer (and we checked the other ones which also had similar problems and the same thing was going on with those).

My best guess or theory was that the audio format somehow changed in between certain takes and that perhaps my computer doesn't have the codec I need to hear that other audio format? Could this possibly be the case? And if so, where would I go or how would I go about finding what I need to play the audio for those parts of the file?

I'd be incredibly grateful if anyone could help me with this problem...

Have you installed the Perian codec available at http://perian.org ?
