1 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 Select the group in which the stabilized clip resides.
2 Apply a Scrape filter to the group, then 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 and Rotation parameters: the black edge is stretched to the right
side of the image.
Track groups
You can apply tracking to groups in Motion.
Corner-pin a 2D or 3D group
You can corner-pin groups using the Match Move behavior.
Do one of the following:
m To corner-pin a 2D group, select the group, then select the Fixed Resolution checkbox in the
Group Inspector.
m To corner-pin a 3D group, select the group, then select the Flatten checkbox in the Group
Inspector. If Flatten is not enabled for the group, the Four Corners option is not available from
the Type pop-up menu in the Match Move parameters.
When you choose Four Corners from the Type pop-up menu, Four Corner is enabled in the
Properties Inspector, causing the group to be rasterized. For more information on rasterization,
see
Groups and rasterization on page 1045.
