Free desktop app developed by Microsoft Research to create your own ‘cinemagraphs’:
Microsoft Research Cliplets is an interactive app that gives users the power to create “Cliplets” — a type of imagery that sits between stills and video, including imagery such as video textures and “cinemagraphs”. The app provides a simple, yet expressive way to mix static and dynamic elements from a video clip.
The software will only work for Windows 7, and currently doesn’t export to the GIF format (video clips only) but is something they are working on (but maybe with some tech knowledge, you could find a way to convert the video yourself).
You can find out more and download the software here, and a full gallery of examples can be found here.
