I am about to make a video in a new genre to what I have been doing for 4 years and it will be significantly more creative. I have spent hours online learning about color grading and the potential that comes with shooting footage on a log profile, and as someone who started out with still photography and Lightroom I am super excited by the potential of log profile footage and Lumetri color processing in Pr.
As I am learning more it seems that shooting 8 bit footage on a log profile is a bad idea because 8 bit footage cannot handle much color grading in post before it starts banding etc.
I just found a reference that indicates that even if the footage output but the camera over HDMI is 8 bit, if it is recorded externally in a 10 bit codec like ProRes HQ that still improves the footage's ability to handle color grading.
Does this ring true?
I will be shooting with a D500 and a D750 both of which produce 8 bit 422 over HDMI and recording in external recorders in ProRes HQ. Is shooting in a log/flat profile to increase DR and flexibility with colors definitely a bad idea? Or might it be worth a try?
