‌Filtering and Filling Gaps in a Track ‌

To produce even smoother final tracks, instead of Locking the trackers, click the Finalize button . This brings up the Finalize dialog, which filters the tracker path, fills small missing gaps, and Locks the tracker(s). Though filtering can create smoother tracks, it is best used when the camera path is smooth, for example, from a dolly or crane. If the camera was hand-held, smoothing the tracker paths causes sliding, because the trackers will be smoother than the camera!

If you have already begun solving and have a solved 3-D position for a tracker, you can also fill small gaps or correct obvious tracking glitches by using the Exact button on the tracker panel, which sets a key at the location of the tracker’s 3-D position (keyboard: X key, not shifted). You should do this with some caution, since, if the tracking was bad, then the 3-D tracker position and camera position are also somewhat wrong.
