  Shimmering Problem w/ Keylight

  Posted by Matthew Weckel on March 30, 2010 at 2:36 am

  Hello-
  I recently shot some footage of some models against a green screen using the Canon 7D in full 1920 x 1080 in h264 and converted the footage to proRes 422. FYI- the footage before I key is slightly noisy(poss. my ISO was too high), and I am using keylight for all of my keying. My problem is that when I am done with all my keying- my models have a very noticeable and distracting shimmering edge.
  Here is what I have tried so far with no luck: the three-pass method where I created a background, core and edge layer; super-tight junk mattes; light wraps; converting the footage to YUV-blurring some green and blue, then converting back to RGB.
  These have helped to reduce the problem, but have yet to solve it completely. I have read every forum post I can find on this problem and none have yet to do the trick.
  Any ideas let me know.
  Thanks!
