This question already has an answer here:

I'm quite new to Blender and have been trying to get into camera tracking for my movies for a while now. I have gone on lots of forums and watched many tutorials but can't fix this problem. Whenever I track a scene and simply test it with a cube, the cube starts moving around and spinning about and things like that. I simply don't understand as I'm very new to this. I have got a movie clip off of a YouTube tutorial and tried to add a cube to test it and the same thing happened. I'm not quite sure how else to explain it, but the cube just keeps moving around.

Please help, Thanks.

EDIT:

Here's the file:

    $\begingroup$ Welcome to the site. ".. just keeps moving around.." is not the best way to describe your problem. Add some screenshots showing your setup, upload your file, elaborate a bit on the problem. See also related answers, e.g. blender.stackexchange.com/questions/42329/… $\endgroup$ – Mr Zak Dec 8 '16 at 23:28
  • $\begingroup$ Hi. Iv'e attached the .blend file. It will be very messy and unprofessional so i'm sorry about that but I hope this helps. :) $\endgroup$ – NFT Gaming Dec 8 '16 at 23:38
  • $\begingroup$ I uploaded a gif of what it looks like on my end, is that what it looks like for you too? $\endgroup$ – eromod Dec 9 '16 at 21:15

Select your cube. Then go into the Properties Editor->Constraints and delete the camera solver constraint.

Your cube thinks its the camera.

This is what I get: enter image description here

  • $\begingroup$ Thanks for the answer. That stopped the cube spinning but now it appears to be moving away from the camera. This only happens in the camera view, not in the 3D view. $\endgroup$ – NFT Gaming Dec 9 '16 at 19:03

    $\begingroup$ here is a link for a tutorial, it takes a minute to learn it but well worth the effort in my opinion. I use gifcam with 640x400 pixel resolution, gif must be under 2 mb to upload. meta.blender.stackexchange.com/questions/963/… $\endgroup$ – eromod Dec 9 '16 at 21:55
  • $\begingroup$ gfycat.com/GiganticOffbeatAnnashummingbird That's what I get. Notice how it is moving away from the camera when the background is added. $\endgroup$ – NFT Gaming Dec 9 '16 at 22:13
  • $\begingroup$ im thinking it means that the solve rate was above 3 blender.org/manual/editors/movie_clip_editor/tracking/clip/… Meaning the points used to calculate the location of the camera need some touch up work. $\endgroup$ – eromod Dec 9 '16 at 22:43
