So I have a question I have been struggling with for awhile. Whenever I bring in live action footage (usually from a music video recorded at 23.976fps) and place it into my scene in c4d and render the footage becomes out of synch. It seems that my frames start to drift or get set to something else.
There's also a fps setting in the render>output options. I'm guessing you've still got it at 30 fps? No way the .024 fps difference between 23.976 and 24 would account for the large shift you're seeing.
