GreenScreen Setup and Keying in Aftereffects.

GreenScreen setup and keying in Aftereffects.

Hey this is Malcholm Reese with mjrvisuals.com and today I’m going to talk about green screen and keying. Now I will be honest I have a print out of ninety nine percent of the editing stuff I do, its really just as a reference because how often in a day do you do everything. Not to often. So for things like particular, or form or even c4d and maya I have cheat sheets on how to get to where I’m going. You ask why don’t I just save the preset, well when new people come to work here and to get them up to speed quickly, it’s easier just to hand them the guide and there you go. It’s like instant experience. Now I say all this because I recommend that you do the same, keep a book or reference folder or something so you can always have something that doesn’t rely on electricity to review. Wow, that sounded old, now I sound like my father. Computers are taking over everything back in my day I did everything by hand! I digress.

So we are looking at my man Ben, on a green screen. Now the only things we are going to pull down to key him out, are Keylight and simple choker.

Pull in your video file into the composition, now duplicate that file.

Pull down key light into the top layer video file, next go to screen pre blur and adjust accordingly, the range I normally use is between 2 and 3. If you didn’t know Pre Blur adjust how much blur to apply to the matte before the key is pulled its good to use as it gets rid of weird edges.

Change the view to screen matte, in this view it’s easy to see what our matte is looking like. Adjust Clip Black and Clip White until the subject or object that is the focus is white and the area you want removed is black.

Next adjust screen shrink then change replace method to hard color and adjust the color. Pre compose the layers and place the simple choker on the pre comp and adjust again I use between .5 and 1.25, there you go export and your ready to use it in your video. Now I will be honest I like to color grade in premier pro with the rest of the files that way I can ensure a perfect balance in color, contrast, saturation with any files that will not have aftereffects in it. It just makes my finished work better.
