  1. Instead of visually instpecting for tracking slippage, use the graphs to find the trackers with the most errors. In the dopesheet you can sort trackers by reprojection error, and delete the ones with high values. Also in the speed graph at the bottom, if you select the points in the graph that are clearly deviating from the average, the tracker will be selected, so you can delete it as well.
    Note that is also important to find the optical center of the lens as well as the distortion, so set the optimization to lens, k1, k2 and optical center.
