PrPro should work natively with the Canon C100 footage ... it works with almost everything out there. And with the C100 shooting MP-4, AVCHD, & H.264, those are all handled easily by PrPro.
My question ... I would surmise (from what little info you include) you are shooting AVCHD? The reason I say this is that format splits audio & video into different files ... so it's a bit trickier to "import" than others that have the a & v in one file. Make sure you copied the whole top-leveL FOLDER and all sub-folders (not just the footage or contents of a folder) from the cam/card into the computer for AVCHD ... and then when you import into a project via the media browser your audio & video should be all connected by PrPro.
There have been numerous threads here where AVCHD users have "lost" their audio, only to find they'd simply left it behind by NOT copying all the folders & subfolders their camera had created.
Thanks Neil, I went back and played the files again and the sound came up. Really weird. I'm not sure whether it was a tempoary disk reading issue or what, but it is now working. I'm relieved and will play around with the file structures to see if that makes a difference. Thanks for your quick answer. Best, Lucian
Glad it's working. I did some AVCHD from my GH3 when I first got it ... but yea, keeping track of multiple-files per shot was a bit of a pain. Mainly, found that the AVCHD out of that cam doesn't hold up as well in the shadows above say ISO 400 or so as the other format out of it does ... so ... haven't shot any AVCHD since. Other cams (like yours) turn out AVCHD as good or better than their other "native" codecs.
