Track Scope
This is a preview image and fine tune window for the currently selected marker. The fade cross stays always in the center, but you can move the image with the left mouse. This automatically records the changed position, and inserts a keyframe at the current position if necessary.
You can pull it vertically bigger by pulling at the handler below the image. And horizontally bigger by pulling out the properties sidebar.
If an anchor is used (the position in the image which is tracking is different from the position which is used for parenting), a preview widget will display the area around the anchor position.

Fake User
Wit this button you assign a fake user to this selected mask. Masks gets created with a fake user already. Means when you save the scene and reopen it, then this mask will still be there.
Data, like images, that is not longer linked to anything else gets removed when you save and reload a scene. Bforartists has the concept of fake users to go around this behaviour. An image with a fake user is in fact linked to something. And so it is not lost when you save and reload the scene.

| Pixel Aspect | The Pixel Aspect ratio of the CCD Sensor in your used camera. This value can be found in the camera specifications. This value can also be guessed. For example, when the footage should be 1920×1080, but the images themselves are 1280×1080, then the pixel aspect is: 1920 / 1280 = 1.5. |

| Set Center | Center the optical center. |
Lens Distortion
