How do you make movies w/ green screen/chroma-key...i mean does the CAMERA matter, or the PC software. Can i just go out and buy a green screen & software for greenscreen, & keep my hard drive camera or what??? I'm guessing the camera has nothing to do with it. PLEASE HELP...

In the old days, say pre-1985, the camera had everything to do with chromakey. The video switcher had to be fed separate RGB channels directly from the camera head so it could make the switch decision based on green being much more that red or blue. Later as more digital electronics were incorporated into the switchgear, it could effectively decode color from the composite video from any camera. Video tape however was generally too noisy and low in color resolution to do a clean key so the foreground was always a live camera.
With digital tape and computer editors, the camera should be inconsequential.

It has nothing to do with the camera. It is an "effect" in the editing software (Avid, FCP) that allows you to key out the color while superimposing another video track as the background. You can also get After Effects which has blending modes just like Photoshop which works in a similar manner (with a white or black screen) but can create even more advanced superimposes because of the different blending modes.
