After placing track anchors and setting your preferences, you’re ready to calculate your tracks. Nuke’s Tracker provides two calculation methods:
• Automatic Tracking - ideal for simple tracks, there are no extra preparation steps once you’ve set your tracking anchors and preferences.
• Keyframe Tracking - a more involved method, requiring you to set keyframes on the sequence in order to calculate tracks. Keyframe tracking may be the better option for more complicated patterns and movement.
