  mask size

  Posted by Marc Nibor on February 22, 2010 at 10:46 pm

  hello,

  i got a moving rectangle in a 3d scene. the rectangle has rounded corners and this is done with a mask (path)

  the content of the rectangle (image or movie) is supposed to stay the same size – but i want to stretch and move it over time.
  the problem is that the mask is stretching and moving too and i dont want that.

  the rectangle is it’s own composition and the mask path is part of the image layer.

  my question is how can i keep the rounded corners, but resize the content (image) without resizing the mask.

  i tried already many variations, checked the help and googled quite a bit but i guess i use the wrong search terms. ; )

  Track Matte.
  Use the mask as a track matte for separate layer. (If they’re moving around in AE, you probably want to parent one to the other)
