  Motion Tracking Wiggles and Jitters

  Posted by Scotteditnyc on August 4, 2005 at 11:37 pm

  I am having difficuties with jitter in my motion tracks after they are applied to the object. some of the footage I am tracking moves a bit fast and that seems to be where I run into problems, but not always since some shots are in slow motion and smooth.

  The footage is interlaced and I try to track with the fields, but that still doesn’t work.

  I tried expanding the motion target, doing a few of the shots myself frame by frame, using the smoother (which does not work because it is taking all the middle key frames away when I apply it).

  One of the shots that I am having the most difficutly with is a shot of a van that is passing by, the shot is in slow motion, and I created a peace sign on the side of the van using the paint tool. I had to do the movement tracking myself because I had nothing to target the tracker on to and the van leaves frame which stops the tracker.

  The manual track that I did works well until just at the end of the shot and then the peace sign wiggles and I can’t get it right. The van seems to be moving smoothly across frame, but no matter what I do, the peace sign wiggles at the end.

  Also, I don’t quite how to apply a motion track to the paint effect. I tried the whip but, it doesn’ work, so the only thing I can think of is to make a pre-comp of the peace sign effect and do it that way. Any help here would be apppreciated

  I just need to find out if there is anything else I can try that can solve this wiggle and jitter problem?

  Thanks,
  Scott
