We do a lot of greenscreen films, mostly with RED One. Will it work fine with AF-100 with Compact Primes for this kind of production? Or is it too compressed? Anyone with reference films (greenscreen with af-100)?
Here is a green screen test on the AF100 outdoors with the screen flapping in the breeze, making it's luminance shift dynamically. Just sunlight with a reflector for a bit of fill. Transparent object, smoke, slow shutter speed. A worst-case test.
don't worry about the camera so much as proper lighting and placement of the screen. it sounds like you're on a set that knows what they're doing, but reminders never hurt
