Hi, I'm new here, first post! I plan to shoot an indie film using a Sony FS100 which is limited to 8 bit color depth, 4:2:0, and about 24 Mbps by the AVCHD codec. This is apparently not very robust for grading, and I do plan to convert the film to b/w in post. I am considering getting an external recorder which would give me 4:2:2 and the potential for much higher bit-rates. My understanding is that the 4:2:2 sampling would help with keying, but staying stuck on 8 bit color depth might cause problems with banding. My question is: in what respects will the higher bit-rate help my latitude in grading, and where might the law of diminishing returns kick in?
Grateful for any insight.
