Objects can be tracked

You can track the movement of elements in your videos and insert masks or objects that follow that movement. For example, you can apply a mask to obscure a face, license plate, or brand logo that is visible in your video.
You can also follow the movement of an element to add a title or object to it. For example, you can pin a name tag on an athlete in a video of a sports event.
How to track and mask an element in a video
1 On the Timeline, in the Edit workspace, select a video clip that you want to track, and do one of the following:
• Click the Tracking button on the Timeline toolbar.
• Right-click on the clip and select the Motion Tracking command from the context menu.

3 Drag in the preview window to apply the shape to the area you want to cover. Fine-tune the mask by dragging the orange node on the mask.

• Track selected mask all images backwards: Chases the selected area backwards from the current point in time until it is no longer recognized on the screen.

If you find places where the mask does not completely cover the selected area, stop playback and adjust the nodes in the preview window. You can change the shape of the mask by clicking the orange mask outline to add a node (the pointer changes to a plus sign), or by clicking a node (the selected node is shown in white) and pressing the delete key to remove the knot.
