Resizing the Reference and Tracker Boxes

Effects > Tracking and Stabilizing > Working with Trackers >

Resize the reference box to make it surround the feature you chose to track more closely. By only including the recognizable feature in the box with no other details that may change throughout the clip, you minimize the possibility of the tracker losing the reference point.

TipSometimes a small reference point does not give good results. Try enlarging the box to include more of the selected feature. Note that the larger the box, the slower the analysing speed.

Resize the tracker box so that it is large enough to accommodate the most frame-to-frame movement of the reference point. For example, if the movement of the reference point is mostly horizontal, you can increase the width and reduce the height of the tracker box. If there is a large amount of movement both horizontally and vertically, increase both the width and the height of the tracker box. Note that the smaller the tracker box, the faster the analysis.

To resize the reference and tracker boxes:

Do one of the following:
- To resize the reference box and tracker box interactively on the frame, press a resize handle on the box and drag.
- To use the menu to move or resize the reference or tracker box for the current tracker, enter values in the Reference or Track fields.
TipUse the image window Zoom command to get a closer view of the tracker and reference boxes.

NoteTo reset the reference or tracker box to its default position and size, select either Reset Ref or Reset Track from the Reset box.
