Join Lee Lanier for an in-depth discussion in this video Using Color Range and Matte Choker, part of VFX Techniques: Crowd Replication with After Effects.
We are down to our last row now, and that last row is composed of two image sequences.…I will change things up a bit, I am going to use a new keyer called Color Range and…a new tool to erode the matte edge called Matte Choker.…So let's bring in the first piece. File > Import > File.…The sequence is called 5A, bring that in.…Just to stay organized, I am going to put that in the Crowd folder and then drop it…on top of my Composition, there we go, rename it, and I am going to turn off the other layers…except for the test layer.…
So this is pretty easy piece to Mask, there is a bit of blue tape here at the top, but…these actors don't move around too much.…Now, if you don't have the layer selected, you will get a new shape layer, I don't want that, so I need to undo.…Make sure I have 5A selected, then draw the Mask, going around that blue tape, there we go.…So we are going to use Color Range this time. So Effect > Keying > Color Range.…Now this is going to look different from keylight.…
At the top is a preview of the matte, we have a bunch sliders here, and also some eyedroppers.…
