If the C4D stuff is going into compositing first I export a 10 bit tiff sequence.
FCP will not take that though. If it is going straight to FCP with no intention color correction 8 bit Quicktime animation is fine. If you intend to color correct make it 10 bit QT animation.
Make your antialiasing “best”
Leave your DPI at 72 as video will reduce it to that anyway.
