# Stabilizing a Perspective Transformation

To stabilize Motion, Scaling and Rotation using Auto Stabilize:

1. Select Tools Composite Auto Stabilize.

   The cursor changes to Pick Front.

2. Select the front clip.

   The cursor changes to Render Here.

3. Click on any free (or a grey) area on the workspace.

   The Perspective button is enabled.

5. Switch to Front View.
6. Optional: Enable the Region Of Interest button.

   Indicate the region you want to analyze on the front clip.

7. Click the Analyze button.

   Analysis takes place. This may take some time however you will see the percentage of progress in the analysis in the Progress field.

8. Switch to Result view to see the stabilized shot.
9. For the Perspective component select either Fixed or Smooth.
   - Fixed pins the component during the analysis.
   - Smooth removes the jittering with 0% being the original motion and 100% removing the highest frequency jitter.

   The analysis is complete.

NoteThe default reference frame is the first frame of the clip. You can change the reference frame of the analysis by defining a new reference point.

To define a new reference point:

1. Position the positioner to the desired frame.
2. Click the Set Frame button.

   The analysis will readapt the timing of the transformation; stabilization will occur before and after the set frame.
