Polyline mask issue

Hello everyone

I am working on a effect in which I can change the eye color. As such I have loaded a clip, then used camera tracking, so far so good. Next I add a poly mask to the clip and that mask turns my clip black. So I say no problems I will invert the mask and the clip comes back on. I then trace around the first eye and once I connect the dots the eye disappears and is now completely black. Next I connect to the camera tracker and move on to the next eye. I add the 2nd poly and have no issues with that one. I trace around the eye, connect the dots then connect it to the tracker. What I am left with is one eye which is black and the second which is the color of the clip. What am I doing wrong please? Am attaching the very simple comp. Thanks

What you need to do is use the polyline where you need to use it i.e. on your color corrector.

So loader-->tracker-->color corrector then add two polylines to the mask input of the color corrector and use your tracking data to drive the center of your polylines. That should get you started.

It's also possible to branch off ie

Loader-->tracker
|
|--->color corrector

This will both work. Just put your polylines on your color corrector.

OK thanks very much I will give it a try.
