To follow up, on the Arri Amira when switching from 12 bit 4:4:4:4 mode to 10 bit 4:2:2 mode, it has a little warning screen come on that says something along the lines of, "Be aware that switching to this mode [10 bit] can cause artifacting." I just about always shoot 12 bit 4:4:4:4 on the Amira. Handles Log-C great, super easy to grade with LUT applied automatically as metadata in post. C300 Mark II, I typically shoot a baked in rec 709 (Wide DR) flavor at 10 bit 4:2:2 as I find grading log to be problematic, nosier, etc.That's surprising, and I guess I would say that what also matters is the degree of compression. 10-bit 4:2:2 with 3:1 compression is going to be more gradeable than with 100:1. For high compression, even if there are no visible compression artifacts like blockiness, the camera has usually first processed the raw footage with strong noise reduction, and that oversmoothness and loss of detail may be what some people might object to when they push the levels around to a great degree. If you have any screenshots, before and after, to help me see what you're seeing, feel free to share them.
