To slow down a clip, iMovie duplicates each frame. The visual result is as if iMovie drew the next frame after a longer period of time compared to a real-speed clip. This doesn't give a flawless playback. The Slow Motion Smoother Effect fills the gaps between two frames, making your clip playing flawless.
(Please let us know if you think we should support older versions of Mac OS and iMovie: email@example.com)
What's new in this version:
Slow Motion Smoother is fully compatible with iMovie 4.
