I want to have blender ignore some markers during camera tracking. I have drone footage of someone running around on a rooftop and shooting at "things" to be added post. I tracked his gun barrel before doing the camera solve. Naturally if that marker is included in the solve, I get a massive error. If I delete that marker, I get a good solve. I spent a lot of time putting in that gun barrel track (frame by frame). Can I tell blender to ignore it (or more trackers) during the solve?

  • $\begingroup$ That is what I did, and then I added an object to save the tracker under. I had to track the gun barrel by individual frame, and I didn't want to throw away 20 minutes of work. I realize that is small potatoes, but I figured it might save me more time in the future. I am beginning to believe it is not possible - that all trackers linked to the camera are used, and that is the intent of the programmers. $\endgroup$ – NoobieStClair Apr 27 '18 at 3:10
  • $\begingroup$ Well, if you would like to keep the marker, you could clear the tracks, then re-track all of them except the one you wish to exclude. Tracks are calculated individually depending on which ones you select, and the solve will reflect that. $\endgroup$ – Dr. Farquaad Apr 27 '18 at 3:13

No need to delete the tracker.

Each tracker can be assigned a weight, which determines the tracker's contribution for the final camera or object solve.

Just bring the value to zero.
