ReVisionFX or Re Vision Effects plugin Twixtor Pro for After Effects
Twixtor intelligently slows down, speeds up or changes the frame rate of your image sequences.
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.
