piStabilize

piStabilize is a video stabilizer plug-in for iMovie and eliminates unwanted shaky motion from video clips.

The stabilization accounts for translations, rotations, and zooming. Margins, a common problem of video stabilization, are filled with appropriate colors to make them less obvious, and they can optionally be reduced by zooming. A smart zooming technique applies zooming dynamically and ensures a minimum of image degradation due to magnification. piStabilize utilizes a caching technique for computed motion, which saves from repeatedly computing motion when reapplying stabilization. This significantly improves performance and efficiency in practical use.
What's new in this version:
Allows for separate stabilization in all directions, i.e. horizontally, vertically, and with respect to rotation and zoom. Customized margin cropping. Fixes two issues with license registration.
