  <p>At the time, a frame by frame edit in photoshop using healing tools seemed the only way to clean up the wire used.  When I tried this however, you get a lot of artifacting that looks fine on one image but differs from frame to frame and creates a fuzzy blur as a video.</p>
  <p>After some learning about the healing tools in After Effects itself, I found out that I could heal a frame using a previous frame:</p>
  <ol>
  <li>Select the Clone Stamp Tool, but don't alt click or set any source points - this means the source point remains the exact centre of the brush.</li>

  <p>Because my footage was tripod shot and was absolutely still, the walls and background didn't move, making it easy to brush out the wires.  In a moving shot this could still be achieved by just offsetting the source of the brush.</p>

  <p>I have a video in which a wire is used to pull an object from the scene.  I did a test which worked well, but the actual shoot didn't go so well, and I've tried several different methods to remove the wire without success.</p>

  <li>I tried a video as the plate, rather than a still, and slipped it a few frames ahead so that the tone closely matches the top video.
