Distorting the Edges
One last suggestion is to experiment with different filters to stretch the edges of the
image to fill any gaps. For example, you can experiment with the Scrape filter to stretch
out the edges of the image. This solution is highly dependent on the type of image and
may introduce other image artifacts that may or may not be acceptable.
In the following image, a large border is created when the clip is stabilized.
Next, a Scrape filter is applied to the group in which the stabilized clip resides. The left
image shows the clip when the filter is first applied to the group. At first, it does not
appear especially helpful. In the right image, the center and rotation of the filter are
adjusted, removing the black edge by stretching the right edge of the image.
Important: The filter must be applied to the clip’s group, not to the clip, for this technique
to have any effect.
Note: You may need to select the Fixed Resolution checkbox in the Group tab of the
Inspector so the effect of the Scrape filter is not cropped.
