best way for green screen

[Kevin Camp]

here is a good tutorial for an easy way to create junk mattes to aid in keying. it’s a very good technique and will almost always help in creating a better key than without creating a junk matte.

the best keyer that comes with ae in keylight (its’ also the one discussed briefly in that tutorial). you may want to read the users guide to better understand some of the features in the effect. if you don’t have it you can download it here.

basically you’ll just pick the color that you’ll want to key, the effect will automatically despill that color from the subject. after that its a matter of tweaking the screen matte settings in the effect to clean, tighten and smooth the matte. there are many other setting you can tweak to further refine the key, spill suppression and some other color adjustments, but that’s the basics.

the best way to get a good key, is not the software as much as it is the setup and lighting and the quality of the footage (i.e. as lightly compressed as possible, standard dv or hdv are not good formats for keying).
