You can stabilize shaky video footage using the Shake Stabilizer option. Shake Stabilizer removes the jitter caused by camera movements, transforming shaky, handheld footage into steady, smooth shots.
Shake Stabilizer is available in both Quick and Expert views. However, for best results, use Shake Stabilizer from the Expert view. The Expert view offers advanced options that help fine-tune the results you achieve with Shake Stabilizer.
It is recommended that you take small sections of the clip that has unwanted shake and then apply Shake Stabilizer. You can trim or split a clip to break it into smaller sections.
For information about how to trim a clip, see Trimming clips. For information about how to split a clip, see Split clips.

Based on your requirements, select a mode to run Shake Stabilizer:
- Quick: Select this mode if you want to quickly analyze a clip and stabilize the shakes. This mode is optimized for performance as it analyzes alternate frames. It takes less time, but the results might not be optimized.
- Detailed: Select this mode to analyze each frame and achieve better results. The Detailed mode takes more time.

Apply Shake Stabilizer from the Expert view
The Expert view is the recommended view for performing shake stabilization on a video clip. You can configure the advanced options available in this view to enhance the shake removal from the clip.

- Motion: Controls the intended result for the footage. Smooth Motion retains the original camera movement but makes it smoother. When selected, smoothness is enabled to control how smooth the camera movement becomes. The No Motion option attempts to remove all camera motion from the shot. This setting is used for footage where at least a portion of the main subject remains within the frame for the entire range being stabilized.
- Smoothness: Use the slider to increase or decrease smoothness in the video clip. 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.
- Video Frame: Defines how the video frames should be stablilized. See Video Frame settings for more information.
- Boost Stabilization: When selected, Shake Stabilizer starts again to find elements to track. When you select this option, an analyze and fix workflow on the clip is initiated. The analysis is slow but produces the best results.
- Rolling Shutter Ripple: The stabilizer automatically corrects the rippling associated with stabilized rolling shutter footage. Automatic Reduction is the default. Use Enhanced Reduction if the footage contains larger ripples.
- Crop Vs Smooth: When cropping, this option 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. See Defining Video Frame for information about the Stabilize Only option.
- Synthesis Edge Feather: Selects the amount of feather for the synthesized pieces. It is enabled only when using Video Frame to Stabilize, Synthesize Edges. 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. See Defining Video Frame for information about the Stabilize, Synthesize Edges option.
You can click Cancel to cancel the effect from being applied on the clip. Click Stabilize to again start stabilizing the clip.
- Motion: Controls the intended result for the footage. Smooth Motion retains the original camera movement but makes it smoother. When selected, smoothness is enabled to control how smooth the camera movement becomes. The No Motion option attempts to remove all camera motion from the shot. This setting is used for footage where at least a portion of the main subject remains within the frame for the entire range being stabilized.
Video Frame settings
The Video Frame option controls how the edge appears in a stabilizing result. This 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 and these are clearly visible around the edges.
- Stabilize, Crop: Crops the moving edges without scaling.
- Stabilize, Crop, Auto-scale (default): Crops the moving edges and scales up the image to refill the frame.
- Stabilize, Synthesize Edges: Fills in the blank space created by the moving edges with content from frames earlier and later in time.
Recommendations for using Shake Stabilizer
- Shake Stabilizer is a memory-intensive and time-consuming operation. While it lets you use the application during processing, it makes the application slow. Once Shake Stabilizer completes the stabilizing stage, the application returns to the normal state. It is recommended to first identify the shaky portion of the footage and then split to extract those portions and run Shake Stabilizer only on those extracted clips.
- If you are applying Shake Stabilizer from the Expert view, try the Quick mode first. The Quick mode is faster but might introduce some unwanted crop in the output. If you are not satisfied with the results, try the Detailed mode. For better results, enable Boost Stabilization under the Advanced section while using the Detailed mode.
- Make sure that project settings and clip settings always match.
- In some cases, the clip mismatches with the current project but matches with one of the application's project settings preset. In this case, Shake Stabilizer requires clip dimensions to match project settings. Create a new project to solve this problem.
- Another possibility is that the clip mismatches with the current project and also does not match with any of the application's project settings preset. To fix this issue, export the clip to one of the standard formats and then create new project using that clip.
