What's the main difference between the different Prores profiles?
For the past year I've been trying to find the best editing codec that works for me. So far I've used DNxHR which so far has worked pretty well however the files sizes are quite big(yes I know they are supposed to be but still). Right now I'm encoding some files to NormanAVC and I'm going to try them out. The next codec on my list to try is ProRes. I checked the Apple website and couldn't really tell the difference between the different profiles other than the bitrate. The footage I encode is anywhere from 10 mbps to 20 mbps. That is well below Prores proxy's 35 mbps. So I was wondering if the lower bitrate will have different performance than say Apple prores 422 which has a bitrate of 147 mbps or the different bitrates are simply to not loose data?
