    pretty self explanitory, most the footage coming to me is a canon 5dmkIII, it can be difficult to pull a good key from this. how good is this sort of footage for VFX?

    Highly compressed footage is never particularly good for pulling keys. There’s not enough color information. Ideally you need footage in a 4:2:2 sampling rate. Here’s a good, concise rundown on why:
