Tracker Data
Tracker data contains information about the Trackers and their frame-to-frame movements during the analysis. This data appears in the Timeline Tracker category when you add a Tracker.
This data is used to apply motion to the element that you are tracking. When you turn off the Tracker, the data is no longer needed and the Tracker category is removed from the Timeline.
The Tracker category contains a Reference folder, a Track folder, a Shift folder, and a Tolerance channel.
The Reference folder contains channels for the position of the reference box, its width, its height, and its type. It also contains delta X and delta Y channels.
The Track folder contains channels for the position of the center of the tracker box, its width, and its height.
The Shift folder contains channels for the X and Y shift values, and a channel for confidence. Confidence is a measure of how much confidence the Tracker has in the match it finds.
Shift values are values, in pixels, of how much the reference feature has moved. The shift values are an (x,y) pair, expressing the motion of the reference feature between two frames.
You can watch the shift values update dynamically as the track progresses to help you gauge how steady the track is.
