If you’ve been trying to use Keylight in After Effects and find that your footage becomes grainy or unusable after using keylight, this video is for you.
Below is a video tutorial for green screen color keying in After Effects. There are lots of chroma keying or color keying tutorials already on the web, and I made yet another one.
In my opinion there are two kinds of color keying tutorials, the one for the beginner that doesn’t really show you how to key your footage and make it look good, and the one for the intermediate user that may be a bit too advanced for the neophyte to keep his/her concentration over.
So I made the one below, that while it won’t make your key perfect, it’ll make it look pretty damn good.
If you watched the video keenly, then you noticed that if you look hard enough (sometimes not even so hard enough if your eyes are trained for it), then you’ll see unacceptable levels of spillage on the skin and clothes of the subjects. If you are a perfectionist and want to get rid of those also, then you cannot rely on the Intermediate Result option. You will then have to use the matte as a luma key. It’s a more advanced procedure, but it gets rid of all the green. Andrew Kramer shows how to do it in one of his videos, I can’t remember which. If you’re unsatisfied with your key, and you really want to know, drop me a line and I’ll do a video on it.
