Just a basic camera test.
The C300 is set to Cinema Lock, so its using the Canon Log picture profile.
EOS Utility 2.11.4 doesn't work on Mountain Lion, so I was unable to instal CineStyle on the 5D
The 5D is using a custom PP based off Neutral. Sharpness: 0, Contrast: -4, Saturation: -2
The C300 was imported through Log and Transfer in FCP7, and the sequence is conformed to those files. The H.264 files from the 5D were brought in natively. No transcoding has been done to any of the files, no color correction applied to any of the clips.
Note the blocky shadows in the lower C300 ISO's. This artificating shows up in both single pass and multipass encodes of H.264 and XDCAM HD 422. The ProRes sequence and ProRes output are both much cleaner. I will investigate this further.
All other relevant data should be in the video. Comment with any questions.
