Keyframe Tracking

Calculating tracks using keyframes can be the better option for more complex patterns and movement. It requires a little more work to set up, but can produce more reliable tracks.

Unlike auto-tracks, keyframe tracking compares the current pattern anchor to the patterns of the two nearest keyframes.

To help avoid clutter in the Viewer, you can enable or disable the Tracker overlay by right-clicking in the Viewer and selecting Overlay, or by pressing O to toggle between the available states:

• overlay off

• overlay on

• overlay on, no animation path

NOTE:  Frame by frame updates in Nuke’s interface can be expensive, and real-time playback can suffer as a result.
The optimize Viewer during playback button in the Viewer tools stops updates elsewhere on the interface during RAM cache playback, helping to optimize the playback frame rate.

See Using the Viewer Controls in the Nuke Getting Started Guide for more information.
