Runway Releases Aleph 2.0 API for Precise Multi-Shot Video Editing

Runway released its Aleph 2.0 video editing model via the Runway API, allowing developers to integrate precise video-to-video capabilities into their own apps. The model supports 1080p resolution for multi-shot sequences up to 30 seconds, utilizing the Aleph 2.0 model for propagating single-frame edits. Video-to-video is a technique where an AI transforms existing footage into new styles while preserving the original motion.

This update moves AI video editing beyond Runway's web interface and into the developer ecosystem. By offering keyframe-guided control via API, the company provides a programmable layer for consistent visual updates across complex sequences. This follows a broader distribution strategy, including the recent Runway MCP server launch that connected its models to AI agents.

Developers can now use the video_to_video endpoint to automate tasks like texture replacement or cinematic adjustments. The API enables precise modifications while maintaining source motion and structure. Access is available through the Runway Developer Portal for integration into third-party creative platforms, products, and websites.

Still wondering? A few quick answers below.

Aleph 2.0 is Runway's flagship in-context video editing model designed for precise video-to-video transformations. It allows users to modify specific elements of a clip, such as textures or environments, while maintaining the original motion and structure across multi-shot sequences up to 30 seconds long.

The Aleph 2.0 API uses keyframe-guided control to propagate edits across relevant shots in a sequence. This ensures that changes made to a single frame are consistently applied throughout the entire video, even when the footage contains multiple cuts or scene changes.

The Aleph 2.0 API supports video editing at 1080p resolution for clips up to 30 seconds in duration. Developers can access these capabilities through the video_to_video endpoint, which is now available for integration into third-party applications and platforms via the Runway Developer Portal.
