What is Gen?

Gen is an AI video generation tool from Runway that creates videos from text descriptions, static images, or existing video clips. You input a prompt or visual material, and the tool generates video content automatically. It's designed for creators, marketers, and teams who need to produce video assets quickly without traditional filming or editing expertise. The tool sits at the intersection of text-to-video and image-to-video generation, making it useful when you have creative direction but lack the time or resources for conventional video production.
