Defining tracker options (Pro only)

After Effects includes several options to help improve the accuracy of tracking as well as select a third-party tracker plug-in and adjust its settings. You access these options by clicking the Options button in the Tracker Controls palette.


Motion Tracker Options dialog box

Track Name

Indicates the track selected in the Current Track pop-up menu in the Tracker Controls Palette.

Tracker Plug-in

Sets the tracking plug-in used to calculate the tracking data for this track. By default, this option displays Built-in, the only tracker included with After Effects.

Options

Displays the Tracker Plug-in Options dialog box, which includes tracker-specific options. The options for the built-in tracker plug-in help you fine-tune tracking. (See Understanding the tracker plug-in options (Pro only).)

Enable Feature Adaptiveness

Causes After Effects to adapt the feature region during tracking to better assist in tracking the feature in subsequent frames.

Track Fields

Tracks the motion in both video fields of interlaced video and doubles the frame rate to ensure that both video fields are tracked.

Note: When you begin tracking, After Effects sets the quality of the motion source layer to Best and the resolution to 100% to improve the image quality and make the selected feature region easier to find.
