  • How to change the shape of a mask in the same video?

    Posted by Rooka Xp on November 15, 2012 at 8:09 pm

    I am making a video and I created a mask with a static shape(ex. square) , I want this mask to stay static for the first minute , then in the next minute I want to edit this mask for another shape(ex.rectangule)which should remain static for the 2nd minute
    the problem is when I change the shape from square to rectangle , the hole clip mask will be rectangle!
    In short: How to make the mask in the 1st minute as a square shape , and in the 2nd minute to make same mask as rectangle ???

    If I’m understanding you correctly, you want a square hole in the first minute, then a rectangular hole the second? You can set a Hold keyframe at 00:00 for your Mask Path as a square, then at the 1:00 mark, change the shape of the mask to a rectangle. A second hold keyframe will be created and when the time indicator reaches that point, the mask will immediately change to the new shape without any in-between animation and stay that way until the end of the comp (or you change the shape again).

    It is easier to destroy than to create.
    More fun, too.
