After having my camera tracked, I decided to put in a cube for testing. But then I've noticed this strange artifact where every object kinda flickers and changes it's rotation.

  • $\begingroup$ note: some retracking and resolving seems to have fixed it, but i still wanna know what the problem was $\endgroup$ – Tin Vojnovic Jan 15 at 22:43

You can clearly see the tracker shifting on the video posted on the question, and it happens at the moment where the reconstruction fails.

Successful reconstruction can only be achieved with accurate tracking

You should aim to have a solve error of less than 0.3 pixels.

There are plenty of tools to help you get more accurate tracking.

  • $\begingroup$ will a better solve also help me with my world alignment issues? i've been having this problem where the trackers and the camera are slightly tilted on Y and X axis and they're not on Z = 0, so I have to rotate my model for it to look good $\endgroup$ – Tin Vojnovic Jan 16 at 9:14
  • $\begingroup$ different questions should be asked in a new post, not as comments... but before you post you can also use the big "search on blender" box at the top. $\endgroup$ – user1853 Jan 17 at 6:17
