I make stop motion animation, and am trying to figure out how to overlay a mouth on a pattern I have for a characters mouth.

Everything is working as it should with the compositing, etc, aside from my plane track. The plane track will not follow the markers that I have placed on the character's mouth. I made a series of markers, traced it over the camera movements, and then merged them.

I then copied and pasted the marker 3 times over to have the required 4 markers to create the plane track.

Once the plane track is created, it appears for the first frame, but any frame past that point it disappears....

What am I doing wrong here?

Image attached of first frame with the plane tracker present. The following frames only show the marker.

After following the steps on the suggested link (How would I attach text to a tracked point on video clip)

I get the following:

  • $\begingroup$ It is unclear to me why you merge different trackers, also what do yo mean when you say that you copied and pasted the "marker" $\endgroup$ – user1853 May 27 '18 at 23:05
  • $\begingroup$ I merge them because the mouth moves fairly quickly as the character's head moves. With 12 different track points the plane track does not accurately follow the spot. When I say I copied and pasted the 'marker', I'm referring to the track points needed for the plane track. I called them markers because the option in the track tab says "marker". Sorry for the confusion $\endgroup$ – Ben May 27 '18 at 23:08
  • $\begingroup$ If you are going to use the information from only one tracked point then it makes no sense to have a plane track, as you are not providing any information to deform such plane. If you only want to move an image using a single tracked feature, then use the translation information from a tracker to move an image in the compositor.

  • $\begingroup$ Just saw that your message had more. Thank you. I'll reply if I have any more questions. $\endgroup$ – Ben May 27 '18 at 23:16
  • $\begingroup$ @cegaton I have used your reference. I have it set up to the composite settings for the section titled, "if the text element is an image and not a 3D Object", yet I have an error showing up. I have pasted it in the original question post. Let me know if you have a solution. Thanks $\endgroup$ – Ben May 28 '18 at 0:24
