Stabilizing an Image
This topic describes how to use the Stabilize effect or the 3D Warp effect to stabilize an image.
The Stabilize effect uses AutoStabilize to track and stabilize an image automatically when you
apply it to a single segment in the Timeline. AutoStabilize uses the tracking and effect parameter
options that are most likely to result in a stable image. In many cases, you do not need either to
interrupt the automatic process or to adjust effect parameters after it finishes. If you need to, you
can adjust parameters after the automatic process, or even retrack.
AutoStabilize does not function when you apply the Stabilize effect to multiple selected
segments in the Timeline. If you want to AutoStabilize multiple segments, apply the Stabilize
effect to each segment individually.
AutoStabilize does not function when you use the Alt key modifier (Windows) or the Option key
modifier (Macintosh) to nest an effect inside another effect, for example, by Alt-double-clicking
in the Effect Palette or by Alt-dragging to the Timeline. If you want to AutoStabilize in a nest,
step into the nest in the Timeline and apply the Stabilize effect directly to the nested layer. For
more information, see “Nesting Effects” on page 269.

The Region Stabilize effect is an alternative option for stabilizing a clip. For more information,
see “Using the Region Stabilize Effect” on page 351.
To stabilize a segment automatically:
1. Apply the Stabilize effect from the Image category in the Effect Palette.
The AutoStabilize process begins and does the following:
- Opens the Effect Editor (if necessary) and the Tracking window.
- Creates a tracker and enables the tracker in the Position parameter for the effect.
- Tracks the image using the FluidStabilizer tracking engine.
- Processes the tracking data using the SteadyGlide option and applies the data to the
image.
- Uses the Auto-Zoom option to adjust the Scaling and Position parameters, which
removes black edges from around the frame.
When the AutoStabilize process ends, the image in the Effect Preview monitor shows the
results of the effect.
You can stop the tracking process at any time by pressing the space bar or by clicking
anywhere in your Avid editing application’s interface. This lets you set different tracking
options, and then track and stabilize manually.
2. Review the stabilized effect and, if necessary, make parameter adjustments.
