Resub// Green Screen Keying Tutorial

Learning about pulling off a clean key is a really important skill needed in the VFX module because if it is done even slightly wrong it ruins the whole illusion of the green screen.

First we imported some footage into AE first we need to so separate the actor from the background then use the screen colour ink dropper to remove the green screen.

Use a screen blur for a smoother edge (use a value of 3)

Change the black and white values to 58 for the black and 75 for the white, this will equalise the black and white for a cleaner key.

Make sure the white background is a pure white, any grey
will lessen the quality of the key.

Creating a Simple choker will also tighten up the edges of the key. Finally we need to separate the actor from the background completely.

Actor Separated from background.

Make a Junk Matte and this will remove all unnecessary background colour. Draw a wide ring around the actor to make account for any extreme movement they might make.
