Losing MXF audio files
I started a new project in Premiere Pro and wanted to load C300 MXF files. The files came into the bin with the second half of the audio missing. The audio plays fine in the Canon XF utility and shows a waveform until the end of the clip. PPro is cutting it off at the halfway point.
When I load the same files into Prelude the audio is intact until the very end. However when I send the Prelude files to PPro the entire audio portion is missing, not just halfway.
Is this a problem for anyone else?

Sounds like a spanning issue. Guessing the files are over 4 Gigs?
Try to bring them in through the media browser.

There is about 20gb of footage.
Upon further review of this the audio isn’t actually missing but out of sync. I have 139 clips of golf. The first 87 clips are fine with full audio and sync. The remaining clips in the bin aren’t missing the the last half of the audio but the sync is out. They finish halfway through the video portion. It’s easy to spot because of the video containing golf balls being hit. The swing and hit and the sound of the hit are there but out of sync.
Very strange when the original files are fine and when I import into Final Cut all intact.

I’ve noticed it seems to take the import a while for the audio to catch up and fully load. That is when I bring in a long take at first the audio doesn’t play, then if I scroll through to the end of the take it will play the video without sound. Leaving it to fully import it eventually catches up.

I see, if you are importing a lot of footage, you might just have to wait until it indexes/conforms the audio. You should see progress on the bottom right.

Thanks for the replies. It is a lot of footage but I actually did wait until all was done. The clips with the out of sync audio start at my 88th file and come in fine in CS5 but not in CS6. It is somehow leaving the entire length of audio but retiming it to half the length of the video portion.
