OK, today boys and girls we're going to delete a blue screen in after effects and do some mask work. We shot a green goblin puppet in front of a blue screen and we're going to load the footage into after effects. First we'll use the key effect and eye drop tool the blue. Play with the settings to your likings. Then we're going to use masks to make some garbage mattes. We'll have to animate the masks so we can cut out sections of the footage that we don't want. Using the 2 techniques of keying and masking you'll know how to pull off this effect! Hopefully this keying and mask animating tutorial will teach you something, either way , thanks for watching! Rotoscoping can be boring!
