Stabilize, Crop: Crops the moving edges without scaling. Stabilize, Crop is identical to using Stabilize, Crop, Auto-scale, and setting
Maximum Scale to 100%. With this option enabled, the Auto-scale section is disabled, but the Crop Less <-> Smooth More property is
enabled.
Stabilize, Crop, Auto-scale (default): Crops the moving edges and scales up the image to refill the frame. The automatic scaling is
controlled by various properties in the Auto-scale section.
Stabilize, Synthesize Edges: Fills in the blank space created by the moving edges with content from frames earlier and later in time
(controlled by Synthesizes Input Range in the Advanced section). With this option, the Auto-scale section and Crop Less <-> Smooth More
are disabled.
It is possible for artifacts to appear when there is movement at the edge of the frame not related to camera movement.
Displays the current auto-scale amount, and allows you to set limits on the amount of auto-scaling. Enable Auto-scale by setting
framing to Stabilize, Crop, Auto-scale.
Maximum Scale: Limits the maximum amount a clip is scaled up for stabilization.
Action-Safe Margin: When non-zero, specifies a border around the edge of the image that you don’t expect to be visible. Thus, auto-scale
does not try to fill it.
Scales up the clip with the same result as scaling using the Scale property under Transform, but avoids an extra resampling of
the image.
Advanced
When set to on, makes the next Analysis phase do extra work to find elements to track. The resulting data (stored in the
project as part of the effect) is much larger and slower with this option enabled.
The stabilizer automatically removes the rippling associated with stabilized rolling shutter footage. Automatic Reduction is
the default. Use Enhanced Reduction if the footage contains larger ripples. To use either method, set the Method to Subspace Warp or
Perspective.
When cropping, controls the trade-off between smoothness and scaling of the cropping rectangle as it moves over
the stabilized image. Lower values are smooth, however, more of the image is viewed. At 100%, the result is the same as the Stabilize Only
option with manual cropping.
Used by Stabilize, Synthesize Edges framing, controls how far backward and forward in time the synthesis
process goes to fill in any missing pixels.
Selects the amount of feather for the synthesized pieces. It is enabled only when using the Stabilize, Synthesize Edges
framing. Use the feather control to smooth over edges where the synthesized pixels join up with the original frame.
Trims off the edges of each frame before it is used to combine with other frames when using the Stabilize, Synthesize
Edges framing option. Use the cropping controls to crop off bad edges that are common in analog video capture, or low quality optics. By default,
all edges are set to zero pixels.
Use when you don’t want to reanalyze footage even though there is a warning banner indicating that it must be
reanalyzed.
The following settings are only available in After Effects CC
Determines the aim for the effect: for stabilizing, for temporary stabilization to perform visual effects work, or to composite a layer into
a shaky scene. Choose an objective:
Stabilize - Default option for normal stabilization
Reversible Stabilization and Reverse Stabilization - Use these options to apply an effect to a region. Use two instances of the Warp Stabilizer
VFX effect, one with Reversible Stabilization to steady a shaky object, and a duplicate instance with Reverse Stabilization to insert the shake
back in, so that any effects you apply after Reversible Stabilization appear within the original scene.
Apply Motion to Target and Apply Motion to Target over Original - Use these options to composite a layer into a shaky scene to apply the
