    Hi I have a clip of a zoomed in eye, and I want to know how to turn the eye a different color (mabye even a firey/darth maul eye) kind of effect. Without having to rotoscope all the frames. Thanks 🙂

    Okay I’ll try that… is there any simpler way to do it?

    Okay well theres not enough contrast between the pupil and the iris and the rest of my skin for it to work right, even with tolerance values of like .1%.

    Anyway, I’m going to try to take a shot with better lighting then try it again. Thanks for the technique, and btw, WHAT ARE GARBAGE MASKS?

    Try searching AE’s help files, then come back if you still need help here.

    Thats actually what I always do first.

    I first searched for luma matte, and then luma, but nothing came up that seemed like a ‘luma matte’.

    I found the Keying effect called Luma Keying but thats the closest I could find.

    When I search for “luma matte” in 6.5, I find:

    Working with Masks and Transparency > Creating track mattes and traveling mattes >
    Using alpha channel or luminance values for a track matte

    … which basically contains a description of the process where you set up two layers in the timeline, “cutting” image above, “filling” image below. With the modes panel visible in the timeline, set the TrkMat button of the lower layer to “luma matte”. The upper layer will disappear, but its luminance will “cut out” the layer below.

    The way you explained it was really confusing it led me to believe that I have to duplicate the precomped layer, then move the original precomp to the top. Whoops.

    Sigh. Again, you aren’t explaning it clear enough for me.. here’s what I THINK I’m supposed to do:

    Part One:

    1. Open a new comp with eye1.avi in there.
    2. Duplicate eye1.avi layer twice.
    3. Select the top one, precomp it (and leave attributes in the comp)
    4. With the precomp selected, apply the change color effect, eyedrop a color in the iris, and set matching tolerance to 2%. Set transfer mode to “ADD”.
    5. Move a copy of Eye1.avi to the top.
    6. Repeat step 4 on this layer instead of the precomp.
    7. Repeat steps 5 and 6 until iris is white.

    Part Two:

    1. Select the precomp layer.
    2. Make the track matte to LUMA MATTE.
    3. Adjust color using Hue and Saturation.

    Am I right?
