> Lesson 1: Track and solve
|
Introduction |
This lesson guides you through the main tasks in Live: tracking and solving. In this lesson you learn how to:
- Review footage to determine the location of tracking points.
- Position tracking points for the live-action footage.
- Track points in the scene
- Evaluate how closely points are tracked using the Track Summary panel.
- Modify the location of tracking points for a scene.
- Import track points into Maya.
- Solve for the camera movement.
- Evaluate and modify the solution that the Solver creates.
Tracking provides Live with information about the way objects in the shot appear to move. Just as objects move in your field of view when you walk by them, the way objects move in the camera view gives Live information on how the camera moved during filming.
You’ll track points for various spots, such as a mark on the fence. To track a point, you mark each spot in the image and have Live run a tracker that automatically follows the point’s movement from frame to frame. The result is called a track point.
Later, in the solve task, Live will animate a Maya camera based on the track point movement.
