trouble with masking
Hi, everybody
I’m new to this forum and i am starting to use Adobe After Effects.
I’m trying to mask a person out of a video. My actor moves a lot and doesn’t keep the same “shape”. I want to cut him out of the video and i did that with the pen tool frame by frame, but when i played it back, everything happened in the same mask. the masks didn’t change throughout the video. I made different shaped masks and it played all in just one of the masks – the largest one. How can I make the masks change throughout the video, in other words, make it play mask-by-mask? Like, make the masks change frame-by-frame? Any help would be highly appreciated.
Thank you. 🙂 -

Dave has pointed you to some useful resources. Here’s a page that goes into some detail about animating masks frame by frame (i.e., rotoscoping):
“Rotoscoping introduction and resources”Here’s a video that shows a simple instance of rotoscoping.

Rotoscoping out a moving person is one of the most difficult and time-consuming tasks in post production. That’s why the color keying process was invented.
Next time, use a green screen.
Or if you have CS5, the Roto Brush will give you a leg up.
