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.
