I have a self contained quicktime prores and an edl that a director gave me all from FCP. The problem that I have run into is when I reconform the edl using the provided edited quicktime for a pre grade as he is not finished with editing completely yet, not all shots link up. He used a mix of camera's a Panasonic 100, Sony F3, Canon DSLR and a GOPRO. Most shot work but some of the clips are showing up as black squares on the construct. Some shots are also not breaking up properly having two or three shots in the construct range.
I have not seen the FCP timeline yet but was hoping someone could help out with this.
