Online video is hot and so are online video APIs. We recently added the Vimeo API to our listings and this brings the total number of APIs at ProgrammableWeb to 19 (see them all here). The king of these is still the YouTube API but for developers there are lots of choices.
The Wevideo API opens up this video-editing-in-the-cloud service. Technical information on the API is available directly from the company. Wevideo provides a solid set of editing and storyboard tools including a timeline and a library of soundtracks. Beyond that, the cloud gives movie editors something else: the ability to collaborate with ease. Because you can create copies of footage, different people can edit the same video as they please.
