I know it is kind a late, but, my Master Collection version of CS4 contained only AVC-I 100 presets meant for p2 it seems.
How do I get the AVCHD presets to use with my new HD files
I had been using only SD presets before, the was experimenting with FCP X for a while
Have been trying to get an idea about what this is that suddenly appeared on my 60 D LCD screen while out shooting, this is not on any of the files either still or video, and is not on the surface of the screen
