How does an F3 output an "RGB 4:4:4" data?

Testing my nanoFlash with my EX3, I only ever noticed a difference when there was motion (shooting at 280Mb/s I-Frame - I only used 100Mb/s L-GOP as a backup for very important event work). I did extensive greenscreen testing with my nano & EX3 and I never found the keying to be any easier or better, but I believe the high noise of the EX3 to be the main reason why.

I am very eager to see the difference in grading ability between the C300 and the F3 recording to 10bit 422 Pro Res HQ (or DNxHD). I also want to see how well the 2 cameras can intercut with one another because I will begin shooting a short film in a month, and I will have access to a C300 to use as a 2nd camera alongside the F3 (recording to a PIX240). I wonder how much of a difference there is between C-Log and the F3's Cinegamma & S-Log.

I've never tested the Nano with and EX1 or EX3, so I can't speak about that, but for the F3 I'm sure there is no visible difference between 35, 50, and 100. I've tested it.
