In this tutorial, Russ Andersson explores the snapping feature in SynthEyes' spot and symmetry trackers. By creating a symmetric tracker, Russ demonstrates how the tracker position snaps to the nearest calculated symmetric point, marked by an X. This ensures accurate tracking without glitches or discontinuities between frames. The snapping behavior can be temporarily disabled by holding down the alt or command key, allowing manual adjustments. Russ also explains that this snapping functionality applies to spot type trackers and works in both the mini tracker view and the main tracker view, as well as in the simul track window. This feature aids in precise tracker placement and helps identify additional reliable tracking points.
