Creating Motion Tracker Effects and Applying Tracker Data

This section provides information on how to apply the Motion Tracker to the timeline to

produce different effects. Other timeline configurations are possible; these are simply the

most common applications.

Using Motion Tracker Data in a Shape Track

You can have one shape track (for example, a text track or a spline object) and follow a

moving point in another file.

To use Motion Tracker data in a shape track:

1. Create a shape track containing the file you want to track. This can be a movie file, a

host video track, or an animated still image file. Name this track Background. This track

will serve as the background of the effect.

2. Create another shape track containing the text, spline, or other object that you want to

follow the motion path. Name this track Track 1. This track’s position is adjusted by the

tracker data.

3. Position Track 1 above the Background track in the timeline. Apply the Motion Tracker

filter to Track 1. Unlike most filters, the Motion Tracker is applied downstream by

default—see “Upstream and Downstream Filters” on page 174.

4. Expand the Motion Tracker filter track to reveal the Source track. Assign the

Background track media to the Source track. You may want to create a duplicate of the

Background track and drag it into the Source track.

5. The Motion filters support Start Time, Clip Head and Clip Tail parameters which are set

in the Source track’s Media tab. The analysis starts at the Clip Head and ends at the Clip

Tail or the last frame of the effect, whichever is shorter. If you don’t want the filter to

apply to the entire track, set a new Clip Head and Tail—see “Importing Movie Files” on

page 143.

6. Generate tracker data—see “Analyzing Motion” on page 496.

7. If necessary, you can manually correct any errors in the generated data—see “Manually

Correcting Errors” on page 497.

8. Select the Motion Tracker track in the timeline. In the Controls window, select the

Apply tab.

9. Set Apply Tracker Data To: to Position.

Track 1 now follows the motion of the media in the Background track. You can continue

to animate or adjust Track 1 and/or the Source track without affecting the Motion

Tracker.
