  Masking: Paint effect

  Posted by Lou Webb on May 30, 2008 at 9:47 am

  Hi there,

  I have 2 images one on top of the other and I want to mask out an animation of the top layer being painted out (erased/masked) to reveal the one behind.

  Can anyone help?

  Thanks : )

  out the animation layer above the revealed layer and then create a new mask on the upper layer that follows the animation
  1.use the pen tool to create a mask2
  2.animate the mask to follow your animation (dont forget to click on the stopwatch for mask shape, wich reveales while hitting M twice)
  3 set the layer beneath your anim layer to use the upper layer as a Alpha trackmatte (cant see options? press F4)

  Thanks for this but I need it to have a pant effect – like a paint brush is painting on the image behind.

  Any ideas?

  Thanks : )

  Use the Paint tool =)

  Then in your timeline twirl down the paint effect and twirl down the brush you just created. From here you can animate the start and end points of the stroke. You might want to do this on a solid, enable ‘paint on transparent’ and then use it as an alpha track matte for your image.
