Matching motion to a tracking path

Using the Match Motion feature, you can automatically match the motion of overlays and titles with a tracking path to create the effect of one element following another. For example, you can identify a moving person in a video by matching a title name to his tracking path.

To match motion to a tracking path

Insert a video with tracking path in the video track.

Insert a title clip in the overlay track and adjust its properties to match your project.

In this example, the name of the boy in the video is added to the title track.

Right-click the title in the title track and select Match Motion. This opens the Match Motion dialog box.

If you have more than one tracker, select the tracker that you want to match.

In the sample video, Tracker 01, which represents the tracking path of the boy, is selected.

Adjust the properties of your title depending on the requirements of your project.

Each time you set a value, a key frame is added.

In this example, Offset values are adjusted to set the ideal distance between the boy and the title. The Size and Opacity values are also adjusted to make sure that the title is visible and yet a bit transparent.

Note: If you need to turn and move the clip around the video, you can set the values under Offset and Rotation. You also have the option to add a shadow and border, or mirror your image. Clicking the Ease in/Ease out button

allows the motion to start out slowly or slow down as it comes to an end. Drag the slider to control the timing.

Play the video to test your animation. When done, click OK.

The result of our sample project is shown below.

You can tweak the properties of your overlays and titles by using key frames, dragging the tracker and adjusting values in the Match Motion dialog box.
