Using a Roaming Reference Box

Use a roaming reference box when the reference feature changes gradually from the first frame to the last frame in the clip, for example, if the reference feature is gradually rotating or changing size or shape.

To use a roaming reference box:

1. In the viewport, select the reference box(es) that you want to set to roaming.
2. On the Tracker panel, select Roaming from the Reference list.

The reference box(es) will be updated at each frame with the contents of the match found in the frame. In other words, the Tracker will always look for a match of the reference feature from the previous frame.

Note: If you later switch from Roaming back to Fixed, the Tracker updates the "Fixed" contents with the last Roaming reference feature.
