I'm setting up a multicam edit (my first in FCPX) with 2 AVCHD cameras and a KiPro ProRes recorded switch master file. I noticed that the 2 camera originals have different colors than the switch master. I've imported both with creating Optimized and not Optimized. I also did not check mark "Analyze video for balance color". Both are a little warmer than the master ProRes. I then Log and Transferred the 2 cameras in FCP7 and brought those into FCPX and they match perfectly to my ProRes Switch Master. Any thoughts on why FCPX is "adjusting" my color on AVCHD import or thoughts on my ignorance is welcome.
I'm on a iMac Pro using FCP 10.4.8 Cameras are Sony NX5.
