On Monday, New York-based Runway announced the availability of its Gen 2 system, which generates short snippets of video from a few words of user prompts. Users can type in a description of what they want to see, for example: “a cat walking in the rain,” and it will generate a roughly 3-second video clip showing just that, or something close. Alternately, users can upload an image as a reference point for the system as well as a prompt.
