RevisionFX Twixtor for FX 6.1.0 | MacOSX | 19 Mb
Twixtor raises the bar in motion estimation. Twixtor is much more accurate, tracks objects farther, and exhibits fewer artifacts when there are objects crossing in the scene. This means less tearing and stretching of objects as they cross or go out of the frame.
