foto jpeg works with 100% in rgb 4:4:4. that is fine for works in after effects (render also internaly in rgb). in fcp is this not fine. use foto jpeg with 75% (works in yuv 4:2:2 with highest quality).
animation is also a rgb codec. fine for after effects. better as foto jpeg, works lossless.
8bit blackmagic is fin in fcp, better for digibeta is 10bit. yuv-codec in after effects is not fine, permanently change colorspace with calculation error…
