When creating 3D projects I usually export the subject out of Cinema 4D in an mp4 format and with a green backplate.

I read that sentence three times to make sure I wasn't missing something.

First, stop doing this. PLEASE. mp4 is approximately the worst format for an element you are going to do further work on. Second, putting in a green screen in said mp4 is beyond non-sensical. You're cutting off your nose to spite your face. mp4 is exactly the kind of format you never want for any kind of green screen work. YIKES! Please stop shooting yourself in the foot, eventually you're going to blow a hole in the floor and annoy your downstairs neighbors.

Export from C4D using ProRes4444 with an alpha channel. OR use an Avid DNxHD codec with an alpha. But please stop using mp4 with a rendered green bg! Doing just this change will solve your problem.
