Apply tracking to a small image

[ignacio]

I'm trying to move a graphic over a video following the head movement of a person,,, the graphic is a image which is smaller than the background video and I compose it with a Comp3d

The problem is that when I track the head on the video and I apply it to the image, it didn't work well, first because the position of the image is reset to 0 (but I can fix moving the curves) but the issue is that only works with position X and Y if I try to apply rotation or size it doesn't match at all

 

any idea??

Hi Ignacio 

did you try to move the pivot in comp 3D to the head in you Background?

when the pivot is in the center of the area you want to track than all the tracking attributes are correct. Rotation and X and Y should work correctly.

hope it helps
