Generates machine learning powered optical flow data for use in one of the Roto based node’s Flow Tracker: Roto, Roto Blend, Tracker, Power Mask, Morph and Depth. Optical flow estimates per-pixel motion between frames and can be used to track shapes and objects.

Sets the motion vector display density.

Controls the motion vector threshold. If the vector length is less than the threshold, it’ll blend the vector alpha toward 0 as the vector length approaches 0.

Use for nodes where accuracy is important, for instance, Tracking.

Use for nodes where accuracy is less important, for instance, Motion Blur.
