Perhaps the most exciting new feature in After Effects CS5.5 is the Warp Stabilizer effect. This effect automatically stabilizes a shot, removing unwanted motion. It is based on our research on subspace video stabilization, presented at SIGGRAPH 2011. Chris and Trish Meyer reviewed the Warp Stabilizer effect on the ProVideo Coalition website.
This feature was recently used by the VFX team behind the Oscar winner Hugo. Watch the Hugo interview here.
