When you are adding elements to a moving image, you essentially have two choices. First, you could analyze the motion of the moving clip and apply that motion to your elements. Or you could stabilize the moving clip, combine all of your elements, and then destabilize the composite. This second method restores the original motion to the finished shot.
1. | Highlight the car clip and select a Stabilize node from the Transform tab.
|
2. | Go to frame 1 and place the tracker over the rear headrest. |
3. | Size the reference pattern around the dark areas of the headrest. |
4. | |
5. | Click the forward tracking button.
|
6. | When the tracker completes its motion analysis, turn on applyTransform.
|
7. | Create a flipbook. The black border that moves around the edges of the image is a dead giveaway that the car image has been stabilized. You are now ready to composite. |
8. | Close the flipbook. |
