  Setting Depth of Field Matte

  Posted by Ben Insler on October 24, 2005 at 3:39 pm

  Hello!

  Does anyone know if you can (and if so, how to) set one layer in AFX as the Depth Matte for another. For example, Lets say I have an image in Layer 1 with no depth information at all and a black and white gradient in layer 2. I want to set the gradient in Layer 2 to be the Depth Matte for Layer 1, so that I can fake a rack focus across the still image that does not really have any depth information. Any ideas?

  Thanks,

  Ben

  AE does not have any real “buffers” and least of all real depth. Some effects such as Compound Blur can fake it by using a greyscale as reference. If your files come from a 3D program, use RPF/ RLA and embed the depth channel. It can then be extracted using the filters in the 3D category.
