We only shoot green screen to product footage for web videos & e-learning material... our subject being primarily spokespersons.
We have stumbled across the new Sony PMW 100, 150 & 200 XDCAM HD422 Cameras. Are they all suitable for green screen? Also, any tips on the settings / color profiles which should be used when shooting green screen with these cameras.
I'll only make some general recommendations since I have an EX1 which is 4:2:0
You'd generally want to shoot flat for post processing.
You do want to light the subject so it will look proper in context of your chosen background in post so keep that in mind when using a profile which is very much dependent on the look you want. You probably wouldn't want to alter individual colors in camera that would adversely impact the Green.
Generally shooting progressive is better than shooting interlaced although the difference might not be as pronounced using a 4:2:2 codec. Some would avoid the GOP altogether and take the 4:2:2 uncompressed out of the camera and record that.
