What does a mocap vendor document for filling marker gaps and choosing a smoothing cutoff, including limits on how much gap to fill?
OptiTrack Motive recommends trimming about 3 frames at gap ends, filling only gaps below a user-set Max. Gap Size (large gaps not recommended), smoothing with a 4th-degree bidirectional low-pass Butterworth at a commonly used 7-12 Hz (higher for fast, sharp motion), and retaking when a significant marker is occluded; edits change raw trajectories and overuse is discouraged.
