Hi all,

a longer while ago I posted about my repeated troubles with serious aliasing and keying issues with my FS7 XAVCI 10bit footage. ( just to clarify straight away, it was in a pro large green studio studio with a pro lighting technician, and the issues were the same as when I set up things myself, so it wasn't due to bad lighting etc ) At the time, for some reason not yet obvious to me, I seemed to get better keying results and no aliasing with DaVinci, so I thought it might be a Vegas issue, as I had tried 4 different keying FX, and a longer mail exchange with the guys from Primatte, whom I had sent some of my FS7 footage and who had trouble getting a good key from it, reason unknown. I had asked around on different forums and got rather dismissive responses when I suggested it could possibly be a Sony codec or camera issue.
Then I stumbled upon this youtube clip of a guy showing that the artefacts in XAVCI were worse that in XAVCS, possibly because ot too low a bitrate. Not sure what to think, but it could explain my green screen issues, especially with hair.

Any thoughts?
