TRACKERS…help!!!!

[lou4uandme]

Hi everyone,
Ok,..I admit, I am an After Effects user, but I am trying so hard to move to NUKE.
I keep going back to AE because I can’t get this TRACKER to work.
For example, I rotoscoped a mans face (Which I plan to color correct).
I then added a Tracker and tracked the nose of the man. So My tracker AND Bezier pivot point are both on the nose. I Ctrl-click and draged the tracking data(via animation Menu) to the translate Bezier . The bezier tracks fine however, its offset,…way offset.
In Ae I would Adjust the anchor point .
why is my bezier masks offset? How can I adjust the position of a tracked mask?
Thanks,
lou

i think you have to link the center of the tracker to the bezier center too. i guess. i ‘ve only touched a bit of nuke.

Hi !

Have you checked if your bezier node was clipped to the right format.
It has to be set accordingly to your project and footage format,
otherwise you might end up with unwanted offsets as nuke XY coordinates start at the bottom left corner of the frame …

Hope this helps …

Hi,

i think you have to match the reference frame no (Tracker/Transform) to Bezier ‘s frame (on which frame u ‘ve drawn the bezier)

Cheers,

Sounds like you are using the track point directly, so it’s translating the roto shape by the x/y position of the track curve, not the difference from the first frame. Go to the Tracker’s Transform tab and pick matchmove as the transform, then apply the translate value there to the translate on your Bezier.
