Tracker Options

Use the Tracker options to help you work with trackers in the image window.

Auto Pan button
  When you zoom in, the selected area may move out of the image window. Enable the Auto Pan option so that the part of the image that is selected stays in the image window when you zoom in.
Opacity field
  The reference image (the image where you placed the reference box) appears in transparency when you select a keyframe. Adjust the opacity of the image to make it more or less transparent. When the opacity is set to 0, the reference image does not appear. When the opacity is set to 100, the reference image is completely opaque.
Zoom field
  By default, the reference box turns into a magnifying glass when you select it. Increase or reduce the magnification factor in the Zoom box.

Zoom: | Result:

1 | No zooming and no crosshair.
2, 3, 4, 5 | A magnification factor of 2, 3, 4, and 5, and a crosshair in the tracker box.
