  • Basic Rotoscope Question

    Posted by Laurie Turner on October 25, 2007 at 12:49 pm

    Okay, say you made a rotoscope matte shape like a box. You go along your 20 sec peice and you are keyframing three of the four points in different locations and shapes. At this point you made a ton of these keyframes and your realize that you forgot to move the fourth corner that just needed to move once.
    My question is, do you have to go to every keyframe to move that one corner to that one spot, or is there a short cut?

    Thanks for your help.

    Thank you Dave

    What my actual project is of a guy in a conference room with big windows. It’s a medium shot and the guy is addressing the camera. Looking out the windows was very blue and uninteresting. So I put in a nice city scape and matted out the windows to show it. The problem is the guy’s head and shoulders are in the way of one window. I roto scoped around him but I would notice that I would miss a spot and would have to go back and fix that spot on all the keyframes.
    Any ideas?

    I think I see what you mean. I am confused to why you would duplicate the layer?

    Have you tried a garbage matte of the guy in front of the window and then applying a key? I’ve been doing some sky replacement and found a luma key in my case saved a lot of roto effort.

    That’s a good idea. I will have to try that luma next.
