Join Lee Lanier for an in-depth discussion in this video Solving bad matte edges, part of VFX Techniques: Crowd Replication with After Effects.
We have got a good start on our crowd.…We have imported two image sequences, removed the green screen, and applied motion tracking.…We can now move on and try to finish up this row. I'm going to import the next piece, which is 1C.…Import File, there's 1C, drop that on top. It's very similar.…Static camera but the camera's is at its leftmost position.…So I'll start once again by drawing the garbage mask.…So I'm going to grab the Pen tool to whittle it down.…
Draw a mask around the screen. It gets rid of all the extra garbage.…And then I can save time by trying to copy the key light from 1B upwards.…So I go to 1B, highlight keylights.…This time I'll use the keyboard shortcut Ctrl+C or Command+C for copy, then go to 1C…and the layer stack and then do Ctrl+V or Command+V for paste.…Then the green screen is removed.…Once again we need to go ahead and adjust that to make sure we have optimum quality.…
I am going to turn on a test background so I can see what's going on.…And then I am going to rename 1C right now before I forget, so it's nice and organized.…
