Raw Tracking
One of the Track Types you can select from in the Track Type drop down is Raw Tracking. Raw Tracking tracks Position or Rotation data only. You can use this option if you decide you do not want to apply the data to the layer, or (as I mentioned) if you wish to apply the data later to an effect, or even use the information in an expression.[an error occurred while processing this directive]Step 10: Make a RAM preview and view the results.

The image is much more stable now, but there are two problems - there is still a slight wobble in video, and the layer moves so much that your viewers will see the edge of the video frame and possibly layers or alpha channels underneath.
 |
| The drawback to stabilizing a shot is that underlying data will show through. |
Step 11: Instead of deleting all of the Anchor Point keyframes and starting over from the beginning, we can easily run another analysis and have the new data append to the old.
Step 12: Double Click the shakycamera.mov layer in the Timeline and in the Tracker Controls Palette turn on the Rotation option and turn off the Position option.
When you do this you will see another Tracking Point. While the position stabilizer applied the calculations to the Anchor Point, the rotation stabilizer will apply the calculations to the Rotation property of the layer. One of the Tracking Points (Tracking Point 1) acts as the base or starting point, while the other Track Point (Tracking Point 2) measures the angle changes between the tracking points from frame to frame.
 |
| The default left box serves as the anchor point for the calculation, while the right box serves to calculate the rotation changes. It does not matter where the boxes are positioned in relation to one another to determine the proper amount of rotation needed to remove the camera shake. |
Step 13: Because we have already positioned one Tracker, we only need to reposition and place the new Track Point. Using the same procedure as before, position Track Point 2 on the corner of a different window.
