Sometimes, a scene can be difficult to track automatically. For example, you might be tracking a set of still photos of a scene with a very wide baseline between images. Alternatively, you might already have 2D track data from an earlier process that you want to get a solve from. In cases like this, it can be easier to only set up and work with User Tracks as your track data.
The key thing to remember is that you typically need at least 8 to 16 User Tracks per frame to get a reliable solve.
