Hi I have a question about After effects. I import a video into after effects and I tried to paint the eyes of a person in the video but the paint keeps getting out of the eyes as that person moves around. I also tried to apply the mask but it still doesn't work. So I tried looking up and found Andrew Kramer tutorial so I did everything like that and applied motion tracking but still the paint keeps getting out of the person's eyes as he is moving throughout the video. Anyone have an idea?

you should post a video or something. hard to tell what the problem is from your description.

The motion tracking in AE is a little bit tricky and if there isn't enough variancle between pixels the keys can jump around. The best advice would be to create a duplicate of your movie and extract all of the color information except for the eyes and use that to create your motion tracking keys (see Andrew Kramers tutorial on how to get rid of acne in a video to see how to isolate a certain color etc..). Other than that you would have to go frame by frame and adjust the keys or re-shoot the video and have the actor wear a positional marker on their face.
