  Tracking motion with color correction

  Posted by Asher Barak on June 12, 2006 at 3:19 pm

  I have a footage where I need to emphsise the eyes of one of my characters. I want to brighten the eye and its surrounding region.
  Or in other words:

  I need to color correct a small region and to move the corrected region in my footage using tracking info.

  So far, I have duplicated the clip, applied bightness to the upper level, masked it over the eyes (with a lot of feathering) and got what I wanted. I also tracked the eye so I have the tracking info. Alas, I cannot animate the mask with the tracking info. so:

  I need to animate a make based on tracking info.

  If some1 could help me with the first question in another manner or solve the sucond one, I would be eternaly gratefull (It is funny, I thought I would find a function doing exactly that or a milion tutorials on the web but came up empty handed…)

  Well a few people have created After Effects scripts for tracking masks (search the archives for more info) I don’t think in this case you will need to apply tracking data to a mask. Instead, I would do as follows:
  -Track the eye
  -Create a solid and mask out where the eye is on this solid (Set mask mode to add)
  -Duplicate the footage with the person who was tracked and place the solid layer directly above it and set the solid layer’s track matte to “Alpha matte”
  -Apply the tracking data from the eye to the solid layer
  -Now do your color corrections on the duplicated footage layer, and the only area affected will be the eye.
