I'm using Premier Pro 2.0. I have several video clips that I need to pixelate the face. So, I created a track matte for the face, a second copy of the video to pixelate, yadda yadda yadda. Works great on most.
But, on one clip, I have zoomed in on the person in the clip by increasing the scale and changing the position in the main clip using keyframes. I copied all that information to the track matte. I then used keyframes to have the track matte follow the subjects face.
It looks perfect when I scrub the image. However, when I render and play back, the track matte moves out of alignment with the person's face. It goes off to the side.
I've deleted and started from scratch several times, and this happens each time. Any ideas what I'm doing wrong?
