Runway Gen-4: New AI Video Generator

Runway has released Gen-4 — its most advanced AI video generator, ready to rival professional filming production and animation in quality.

This latest version of Runway AI marks a major step in text-to-video technology, offering unmatched visual fidelity and full creative control. Most importantly, Gen-4 maintains consistent characters and objects throughout entire videos — something previous models struggled to achieve. Both individual creators and enterprise users on the Runway platform can start using it today.

‍

What is Runway Gen-4

Gen-4 is Runway's latest artificial intelligence video generation model designed to translate ideas into high-quality, cinematic videos using nothing more than text prompts and image references.

Gen-4 significantly outperforms its predecessor (Gen-3) in visual quality, realistic movement and character consistency. It is capable of simulating camera movement, keeping objects consistent across multiple scenes, generating natural lighting and physics, and following stylistic requirements.

Gen-4 allows you to create videos that look and feel like professionally made videos without the need for traditional animation or editing tools.

‍

Key Features

Runway Gen-4 offers a large set of updates that define new AI-generated video capabilities, from improved realism to intuitive creative tools. Here are the key features that set it apart:

‍

Characters in different scenes

Gen-4 keeps characters and objects visually consistent across the entire video — from facial features to proportions — even when changing angles, lighting, or camera movement.

‍

From text or image to video 

Gen-4 lets you create videos from a simple text prompt, a reference image — or both. Describe the scene you want, upload a visual for style or subject reference, and the AI will generate a consistent, cinematic result that reflects your intent.

‍

Cinematic quality 

Gen-4 delivers a high level of AI video quality - with better depth, lighting and motion. It creates footage that looks like it was shot with a real camera, not machine-generated.

‍

Realistic physics and motion

From flowing fabric to dynamic running, Gen-4 simulates real-world movement and physics with stunning accuracy. Movements look smooth and natural, enhancing believability and immersion.

‍

Style Preservation 

Gen-4 consistently applies your chosen style - cinematic, minimalist, natural or surreal - throughout your video. Each frame remains visually cohesive.

‍

Editing by Layers

Gen-4 allows you to edit individual elements of a scene - backgrounds, objects or characters - without affecting the rest of the video.It works like layers in Photoshop, giving you the flexibility to work on your content with the ability to perfect your creative intent. 

‍

Multiple Angles, One Scene

Gen-4 lets you generate a full scene from different angles and camera positions — based on a single prompt and reference image.

‍
