Calculating Auto-Tracks

To calculate auto-tracks:

1.   In the Tracker properties panel, select each track you wish to calculate or click select all to use all tracks.
2.   For each track, select the type of movement the track is intended to output: translation, rotation, or scaling. For example, tracking a feature across the sequence and toward the camera may involve translation and scale.

NOTE:  These controls deal with output from tracking data using the Transform controls and are not the same as the Settings > warp type control, which deals with pattern recognition.

3.   Using the tool bar above the Viewer, click either the frame backward (X) or forward (C) buttons to move to the previous or next frame. Move through a few frames in this manner to ensure that all enabled track anchors are “sticking” to their patterns.

If a particular track anchor doesn’t stick, experiment with a different position.

4.   Once all track anchors stick, click the track backward (Z) or track forward (V) buttons to analyze the whole sequence.
5.   To track only a certain frame range, use the range buttons to enter the required frames.
6.   Click stop (Esc) , to cease tracking in either direction.

TIP:  When calculating multiple tracks simultaneously, you may find that some tracks stick accurately to the pattern, while others require resetting and reanalysis. When you’re happy with a given track, deselect it in the Tracks list. This protects it from recalculation, and lets you experiment with better placement for the wayward tracks.
