  • stationary layer mask with moving image?

    Posted by Patrick Collins on August 1, 2008 at 7:35 pm

    Hi everyone,

    I have a somewhat large image that I only want 1/4 of revealed… I
    then want to animate the image so that as it moves, the area that is
    revealing the 1/4 stays in the same spot, butt the image moves
    around– basically like a cut out.

    I thought I could accomplish this by using a layer mask, however when
    I move the image, the mask moves with it, and I tried locking the
    mask, but it still seems to move with the image. Can anyone please
    guide me on how to do this?

    thanks!

    it could be as simple as a precomping the image and it’s movement. then place that in the ‘main’ comp and create your mask for the 1/4 part that stays stationary.

    This is what I’ve always resorted to. I was reading this thread hoping there was an easy simple way of doing it without having to create a new composition.
