Tracking a bezier?..newbie

[arjan_meerten]

Hi,
Yes I watched all the tutorials on nuke's website, and no, I have not learned how to track a mask.
For example, I have man's face that I tracked. I want to apply a mask around his eye area and use a cc node to darken the area. So I:
1 tracked the eyes.
2 Traced a mask around eyes
3 Plugged the bezier into the "mask" input of the cc node.
If I press "match-move" on the tracker, The whole image moves around.
So I removed the tracker, cc node & mask
and "Merged" them.
Although the mask track great, I am not getting the cc node to show up.
I have been going nuts trying to get this simple task to work.
Can someone help me?
Thanks,
Lou

Hi,
Points 1 and 2 are correct. You only have to connect the bezier to the tracker and set it to match-move, then connect the Read node to Color Correct and the tracked bezier, matching the moving of the eye, in the mask input of CC.

That's all, bye![img]none[/img]

You have to connect the tracker below the bezier in the node tree for it to work when you set it to "Match Move", because the Tracker node will affect everything above it. You only want it to affect the bezier right.

So first you track the data then you move the tracker node.

Another thing you can do is holding down SHIFT and draging the tracker data over to the bezier.

There is a curve icon next to the tracker translation, drag from that over to the "Translate" data in the "Tracker" tab of the Bezier.

I know my explanation sucks on the last one but if u don't understand I'll post an image.
