Runway developed Gen-2 as a text-to-video model building on latent diffusion, first solving temporal consistency with Gen-1 using input video conditioning, then removing that requirement for Gen-2. The company's north star is enabling generation of a two-hour film, and it follows a staged release approach for safety and organic use case emergence.

## Evidence

Verbatim from https://runway.com/research/scale-speed-and-stepping-stones-the-path-to-gen-2:

> We decided to solve a simpler version of this with Gen-1: you have an input video as conditioning, which determines the structure of the output video. A few months later, we released Gen-2, which removed the need for structure conditioning and tackled text-guided video generation directly.
