Tracking motion of video objects

The Track Motion feature allows you to track the motion of a point or area in a video and automatically generate a tracking path in the process.

Track Motion works in tandem with the Match Motion feature. Match Motion allows you to make your overlays and titles automatically follow the tracking path that you create.

If you prefer to manually animate overlays and titles to match your main background video, you can use the Customize Motion feature.

To track the motion of video objects

Click Tools > Track Motion.

Browse for the video that you want to use and click Open. This opens the Track Motion dialog box.

In this example, a video of a boy walking by the lake is selected.

Drag the tracker to the part of the video that you want to track.

In the example, the tracker is dragged to the face of the boy. The area is magnified to give you a closer view of your selection.

Note: If you want to select a larger area, click the Set tracker as area button

in Tracker type. You can adjust the shape and size of the tracker by dragging the corner nodes.

Click the Track Motion button

The video is played as the tracking path is generated. If Show tracking path is selected, the tracking path is displayed and highlighted once the tracking process is completed.

Click OK.

It is easier to track points or areas in your video that are distinctly in contrast with other video elements. Avoid choosing pixels that may blend with similar pixels in the video.
