Wow, thanks – great answer.
I work A LOT with ProRes as Im usually dealing with SLR footage. I common step in my workflow is to take ProRes clips, or other video assets, that need dramatic color correction (beyond what I’m doing in FCP) or some simple compositing. To get them back into the edit, I’ll render out in ProRes (so the clip sits natively in the sequence). Is that wrong? Should I be rendering out animation and compressing that with QT or compressor, then?
