Answers
1.
Shake has three tracking nodes: Tracker, Stabilize, and MatchMove.
2.
A reference pattern defines a small pattern that will be searched for in subsequent frames when tracking; the search region is the maximum amount your track point will move between frames.
3.
Use the Average Tracks function to combine multiple tracks.
4.
Offset tracking is used when your reference pattern becomes obscured. In this mode, the track point follows the same path, but a new search region or reference pattern is used to acquire the tracking data.
5.
The SmoothCam node is an alternative to the Stabilize node for stabilizing images and is more automated.
6.
HueCurves is a process that effectively removes a particular color from an image.
