Thanks everyone for your thoughts.
My understanding of codec’s, bit rates, resolution etc.etc, is that once you film it, it’s not going to get any better.!!!! ( If I’m wrong can anyone suggest a workflow for upresing Hi8 640 x 480 to at least 720p.)
So the only difference is in workflow, if I work in ProRes 422 is it only because it is easier on the processing power of my mac..?? especially if Color Grading, effects etc. ?? What are the detriment of not transcoding and just editing the H264 mp4 files.??.
Considering that I film in 4K, and output to youtube at 1080p, as I like the opportunity to crop in when editing. How noticeable would any image loss be.??
