Hi, guys.

There's something that always bugged me about fs700 and odyssey 7q on 4k>ProResHD or 4k>ProRes UHD: skin tones. So I made a test yesterday comparing Odyssey 7q's Prores vs Raw vs Red Scarlet and found this:

1- There's a terrible banding from highlight area of the skin to the shadows. Check the nose area on 4k>UHD image. Until it reaches the shadows, there's a greenish sharp line inbetween.

2- 4k>RAW is much better, though it has a magenta tint that is hard to get rid of. It's easier to match Red Scarlet and 4k>ProRes UHD than Red Scarlet and 4k>RAW.

Is there anyway to fix this skin banding (don't know if it's the right name)? LUTs? Better exposure? I tried underexposing a little and it's always there, the skin problem.

THE TEST, check out the frames:

Exactly what I've seen on my footage as well. SUPER annoying since I've already shot 80% of a feature film with the Odyssey and no fix... Gonna be a grief in color grade! :(
 
Could be economical to rent a RED and shoot with that instead if one is going to try and remove this in post...
 
Exactly this problem destroyed a lot of my projects. only fix is, never underexpose skin! Its one of the main reasons i need to upgrade to a FS7 and use the internal recording.
PLEASE Mitch, fix this asap, this makes the whole prores mode so much more unusable :( Thank you
