I tracked a scene, solved it, and used a Refine Solution Addon to better my track, and got a solve error of .0018. I set the video as the background and set up the tracking scene by clicking the buttons. I began to notice on the 3D view, the markers are not on the tracks. As well, I set the floor to three points on the table top, and in the final render, the cube added appears to be floating. I'm not to sure why it's off. Is there a way to fix this, so the markers are on the tracks, and the box does not float?
The markers are parented with the camera, and so they won't get positioned correctly if I move the camera to a certain spot.
