GUESSING…
My guess is that Pro Res is always 10bit and Media 100 edits in the native codec, not changing that.
What about ColorFX? What bitdepth does that support?
A lot of legacy effects have been carried over from Media 100i – so I would guess the “classic” options would be processing in 8bit.
RGB Levels were introduced with Media 100 HD (I believe – I could be wrong) which supported 10bit uncompressed.
I’d guess they would process in 10bit. Or did they overhaul all of ColorFX to process in 10bit?
If you say Boris Red has settings for bit depth, that at least is encouraging.
It implies the filters could work at those bit depths, and then render the results back to the 10bit codec.

KNOWING…?
Guess, guess, guess, guess, guess… =).
It might be good to actually know, =).
Am guessing someone technical from Media 100’s past development may have more insight.
