Runway's video generation model for creative teams
Runway Gen-4.5 is a video generation model from Runway, a company that builds AI tools for filmmakers, editors and designers. Runway released it in late 2025 as the next step after Gen-4. It is offered in Runway's own web app and to developers through Runway's API, alongside the company's other video generation and editing tools.
Runway presents Gen-4.5 as a step forward in motion quality, physics and camera movement, with closer prompt following than earlier versions. It is aimed at shots that need a deliberate camera move, believable action, or textures such as hair and fabric that stay consistent over time. Like other video models, complex cause-and-effect action can still need several takes before it reads right.
Runway Gen-4.5 is not available in Cinemagiq. Two other Runway models are: Runway Aleph 2.0 edits an existing clip with a prompt and up to 5 keyframe images, and Runway Act-Two transfers a performance onto a character. For generating new shots, Seedance 2.5 works from a prompt, frames or references for up to 30 seconds, and Kling O3 animates a first frame for 3 to 15 seconds.

No. Runway Gen-4.5 is not available in Cinemagiq. Cinemagiq does run two other Runway models: Runway Aleph 2.0 for editing an existing clip with a prompt and keyframe images, and Runway Act-Two for transferring a performance onto a character.
For new shots, Seedance 2.5 takes a prompt, frames or references and runs up to 30 seconds with optional sound. Kling O3 animates a first frame, with an optional last frame, for 3 to 15 seconds. To change footage you already have, use Runway Aleph 2.0.
Runway positions Gen-4.5 for shots that need believable motion, physics and camera movement from a text prompt. It fits deliberate camera moves, action beats and teams who already work inside Runway's tools for editing and finishing their footage.
Yes, with Runway Aleph 2.0. It edits a clip of 2 to 30 seconds using a prompt, up to 5 keyframe images, or both. Every result lands in the Asset Hub, where you can add it to a shot on the Production Board.
Cinemagiq runs the leading video, image and audio models in one AI-native workspace, so you can pick the right one per shot.
