Mocha Pro is a planar tracker with support for both rectilinear and immersive video, and works best for 360 shots where the horizon is visible and there are clearly trackable elements visible in the frame. For example, when filming on a boat or stabilizing drone footage, it is easy to track some of the clouds in the sky and reorient the horizon. Mocha Pro's tracking works well when elements of the shot do not disappear, as this causes the tracking to fail. It is also performs best when there is a consistent horizon line for it to reference.
These videos below were produced using an earlier version, Mocha VR, but the fundamentals and primary features are still applicable in the current version, Mocha Pro.
