I've edited family video shot from my Canon DSLR and want to export at high quality to keep long term on a hard-drive. I optimised the video in Final Cut Pro X while editing. What is the best way to export to keep best quality and reasonable export time? Should I export as ProRes, as H.264, or uncompressed? Is using a Quicktime movie best? Thank you.
Optimized media in FCP X parlance is Pro Res 422. Here is a very good article on Proxy versus Optimized.
If you were adding a lot of graphics to you movie, or if you were sending it to a professional for color grading, there might be a case made for PR HQ. But for most people, PR 422 is perfectly fine. BTW, Pro Res 444 is PR HQ with an alpha channel added (for transparency).
Apple just out with somethirrg on native editing; notice that h.264 was not among those that will edit well. It will edit but it's easier in Pro Res…and it's my opinion that Pro Res treats graphics and text better. Whether it exports faster, I'm not sure. As I said I find exporting Pro Res to be rather painless,
