Would the PL-A742 from PixeLINK be the greenscreen solution?
It cost less than most 3ccd video cameras. What else would be needed for this to be used as a stationary greenscreen camera?

This camera displays an atrocious "chromatic aberration" Have a look at the sample images provided; those pix, I was told were taken with a cheap video lens. Imagine how bad the CA wil be when shooting with a good quality lens. I am sure that a good algorithm could be written for the conversion from RAW to RGB to eliminate or contain the sensor's CA.
Otherwise looks like a nice, easy to use setup. Very tempting.
