FrameStacker at Mac App Store analyse

FrameStacker is great for creating star trails, streaky clouds, and interesting sports videos.

FrameStacker lets you stack the frames of a video using a wide variety of blend modes. You just choose a movie file, pick a blend mode, and specify how many frames to combine when building each frame of the output movie. For some videos made with the app, visit https://www.youtube.com/playlist?list=PLNoXydjy2lnOMNCnf5PEkaej6eCP9WOS2 .

FrameStacker can stack frames with all of the following blend modes. (Note that not all of these blend modes produce interesting results; in general, youll want to stick with Lighten or Darken. But I included all of them just for the sake of completeness.)
