Remove borders from stabilized clips in Motion

When you use the Stabilize behavior, the resulting transformations that smooth or stabilize the shot cause moving black borders to appear around the edges of the image. Although this is necessary to achieve the desired effect, you probably don’t want these black borders to appear in the final shot.

Use the following methods to remove black borders.

Zoom the clip

You can zoom the clip using the Borders pop-up menu in the Behaviors Inspector. Be aware that zooming the clip may soften of the image.

  • In the Behaviors Inspector in Motion, choose Zoom from the Borders pop-up menu.

    The clip is expanded to the full size of the canvas, preventing black borders from appearing around the edges.

Scale the stabilized clip

If you want to output the resulting clip at the same size as the original, the quickest fix is to scale the image after the Stabilize analysis. You’ll need to enlarge the image to the point where all instances of black borders fall outside the edges of the frame. Like the Zoom option (in the Borders pop-up menu), this method softens the image.

Note: This workflow is a manual version of zooming the clip using the Zoom option from the Borders pop-up menu.

  1. In Motion, select the clip and open the Properties Inspector.

  2. Adjust the Scale parameter so the borders no longer appear at the edges of the clip.

Distort the edges of the clip

You can experiment with filters to stretch the edges of the image to fill gaps. The following example uses the Scrape filter. (This solution is highly dependent on the type of image and may introduce other image artifacts that may not be acceptable.)

  1. In Motion, select the group containing the stabilized clip.

    In this example, the project background is white to better illustrate the clip’s shift in position due to the stabilization.

  2. Apply a Scrape filter to the group, turn off the Crop checkbox in the Filters Inspector, then adjust its parameters. You can also use the filter’s onscreen controls to adjust the Center and Rotation parameters.

    The left image shows the clip when the filter is applied to the group. The right image shows the result of adjusting the Center parameter using the onscreen control: the top edge is stretched to the top of the canvas.
