Now the first thing I want to do is make a foreground selection, teach Roto Brush …what I considered to be the foreground object in this layer and namely…it's this actor's hands and arms.…Although it is just his hands and a little bit of his wrist that go in front …of the screen, quite often, it's better in the long run to select large continuous…portions of a person's body.…If I selected only part of his arm, I might get a matte line, …a bit of difference or distinction where the Roto Brush version of his hand …in the foreground joins up with the normal copy footage in the background.…
So I'm going to select the Roto Brush tool, hover my cursor over the Layer panel, …and you'll see this little green cross.…This green circling cross indicates I'm about to define the foreground portion …of the layer.…Now unlike normal painting you don't want to or need to make very precise…strokes right along the edges between your foreground and background.…Roto Brush is the one who's going to determine where that edge is.…
