I've been looking, but haven't found the exact answer to this question. I'm shooting a doc with my 7D and would like the final output to be good enough for projection.
It's my understanding that the Canon H264 bitrate is 48 mbs. (I'm shooting 24p/1080p). ProRes LT is 102. ProRes 422 is 147. Am I gaining anything if I transcode to ProRes 422, or is ProRes LT (already twice the size of H264) just as good?
