What kind of camera is needed for keying video?

The camera requirements for keying are not very strict, and any camera that can manually control the exposure will do. Of course, it would be best if the camera is of broadcast quality.

To ensure the effect when keying, the most important thing is the choice of lighting and background color during shooting. When lighting, it is best to have uniform illumination on the left and right sides, with a clean background and clear outlines.
