Hi ZG,
If that works for you, great. You need to work with a mask then, which needs to be animated, etc. See link.

I never had luck getting an automatic 2D track in the quality I like to have, while at the same time a sufficient number of trackers for an object are available as well. To have from start to finish the needed amount of features, I add trackers, and after the first iteration. However, the 2D features on the moving object disappear as expected (… no mask!). Hence, why I mentioned the mask feature, for a suggestion. Since more than one object can be tracked, this would need a better handling than we have now.
I assume that they are seen otherwise as a mistake as the camera tracking is the prime target. If they are kept with equal weight (concerning value), I would have little trust in the following solution.

Anyway, I have the best results with manual trackers, so I have maybe a blind-eye for the mask based workflow. *Having said that, I invested a few hours, made different traveling mask and had even close the results that I get with manual trackers, given the “blaster scene”. I do those things as everything changes, and for the current version, I would go again with manual trackers from the start, instead of wasting a lot time to make a good traveling mask. But, each scene is different of course.
My best wishes for your project.
P.S.: Since I know the developer, of this part of the app, since long, I have sent him an email to clear this point. I love first-hand information.
