A Prisma for videos doesn't sound so enticing now that Prisma itself has begun supporting the format. The popular app can now apply filters to videos and spit out 15-second snippets that look much more artistic than their source. Even better, it can process files even if you're offline, which the team made possible by optimizing the algorithm. The bad news? Only the iOS version of the app supports videos for now, but the team is working on bringing the feature (along with offline processing) to Android.
