Runway Gen 4.5

Runway Gen 4.5 is an advanced General World Model built for cinematic video generation. Unlike conventional generators, it understands how the real world works, simulating physics such as gravity, fluid dynamics, and object interactions so that every scene moves with a level of realism that is hard to distinguish from footage.

The model is powered by Latent Diffusion Transformers and multimodal training, giving you precise creative control over your shots. Director Mode 2.0 lets you direct camera movement like a filmmaker on set, while Motion Brush 3.0 allows you to animate individual subjects independently, so characters and objects can act on their own without disturbing the rest of the frame.

From a simple text description or a single image, you can generate high-definition videos in seconds at 1080p quality. Multiple aspect ratios are supported for different platforms and formats, and style transfer capabilities let you apply a consistent visual look across your projects, making it a practical tool for creators, marketers, and storytellers who want polished results fast.
