Camera tracking needs precise, hand-tailored 2D tracks. The promise of automatic 2D tracking is grand, but often fails expectations — mainly because auto-tracking algorithms cannot reliably link points which disappear or get obscured. For many shots 2D tracking by hand is a better option (it also allows you to speed up the solve by using less features). However, the solve also depends of the algorithm and it’s always beneficial to try the solve in all the matchmoving software available. Solving with the same features also gives a good comparison between different camera solving engines.
Tracksperanto allows you to track once in a program of your choice and then export the resulting features to all suppoorted 3D solving apps. Once there, it’s a 15 minute job to configure the camera and see if the solve comes out well or not. This method tends to yield very good results since you track at least one of the many 3D solvers on the market will give a correct computation. (more…)
