Hi everyone. I am trying to take a video of a local kids play I recorded and change one character to ICE during one scene. Basically I want to create a 'frozen' type of effect and have the little girl turn a shade of blue. I've figured out how to do this using ONE mask which is the filled in body of the child creating a hole. I then put a blue color on the track above and then keyframed opacity on the mask so it fades in and out just for that scene. This it works fairly well even though she moves her arms a bit. The problem is that another character walks partial in front of her for 1 or 2 seconds thus the inverted blue mask shows on her for those seconds she's blocking the other child. I'd love to apply multiple masks to the video but I don't think it's possible. I tried creating a second mask on the color track but couldn't figure out how to make that work at all. That wouldn't solve the issue fully anyway.

Please let me know if anyone has any ideas on this. Also, when I fade out the mask for some reason I see the blue color on the outline of the screen for a few seconds as well. Not sure how to fix that either. Thanks!!
