Analyze
There is no need to press this button when you first apply Warp Stabilizer, it is pressed for you automatically. The Analyze button remains dimmed
until some change takes place. For example, if you adjust a layer’s In or Out points, or there is an upstream change to the layer source. Click the
button to reanalyze the footage.
Analysis does not take into account any masks or effects that are applied directly to the same layer. Pre-compose and place them in the
upstream composition if you want them to be analyzed.
Cancel
Cancels an analysis in progress. During analysis, status information appears next to the Cancel button.
Stabilization
Stabilization settings allow for adjusting the stabilization process.
Controls the intended result for the footage (Smooth or No Motion).
Smooth motion (default): Retains the original camera movement but makes it smoother. When selected, Smoothness is enabled to control
how smooth the camera movement becomes.
No Motion: Attempts to remove all camera motion from the shot. When selected, the Crop Less <-> Smooth More function is disabled in the
Advanced section. This setting is used for footage where at least a portion of the main subject remains within the frame for the entire range
being analyzed.
Chooses how much the camera’s original motion is stabilized. Lower values are closer to the camera’s original motion while higher
values are smoother. Values above 100 require more cropping of the image. Enabled when the Result is set to Smooth Motion.
Specifies the most complex operation the Warp Stabilizer performs on the footage to stabilize it:
Position Tracking is based on position data only and is the most basic way footage can be stabilized.
Position, Scale And Rotation Stabilization is based upon position, scale, and rotation data. If there are not enough areas to track, Warp
Stabilizer chooses the previous type (Position).
Perspective: Uses a type of stabilization in which the entire frame is effectively corner-pinned. If there are not enough areas to track, Warp
Stabilizer chooses the previous type (Position, Scale, Rotation).
Subspace Warp (default): Attempts to warp various parts of the frame differently to stabilize the entire frame. If there are not enough areas
to track, Warp Stabilizer choose the previous type (Perspective).
The method in use on any given frame can change across the course of the clip based on the tracking accuracy.
note: In some cases, Subspace Warp can introduce unwanted warping, and Perspective can introduce unwanted keystoning. You can
prevent anomalies by choosing a simpler method.
(After Effects CC) When enabled, prevents the Warp Stabilizer from trying to adjust forward and backward camera movements
with scale adjustments.
Borders
Borders settings adjust how borders (the moving edges) are treated for footage that is stabilized.
Controls how the edges appear in a stabilizing result. Framing can be set to one of the following:
Stabilize Only: Displays the entire frame, including the moving edges. Stabilize Only shows how much work is being done to stabilize the
image. Using Stabilize Only allows you to crop the footage using other methods. When selected, the Auto-scale section and Crop Less <->
