There's a philosophical difference between delivery codecs (e.g. mpeg4, avchd), editing codecs (e.g. DNxHD, ProRes, Cineform), and capture codecs (e.g. r3d, DVCPROHD). While almost any codec can be used for each of these three stages, your workflow needs will help you decide which are best suited for each stage. The question you seem to be asking, is ...

Check your format settings; you might need to specify a different byte ordering (also called "byte swapping") or tell it to be explicitly 16-bit instead of, say, 24-bit. In Quicktime you can see what the audio format is via ...

There is an update forthcoming but until then they suggested this as a work-around: Move the AppleProResDecoder.qtx from the /Quicktime/QTSystem/ folder to a temp folder. I still get some inconsistencies ...

When patterns are found, it can store the data once and reference the stored copy. The second is only used lossy compression and involves discarding the least significant ...

I've never encountered this problem, so unfortunately I can't give you advice on how to fix it. However, next time, I would suggest that you convert all your footage to the same format before you begin editing. Prores 422 is a great editing codec. Go to this website and download MPEG Streamclip. It's a free program that converts your footage to different ...
