What is Runway?

Runway is an AI-powered creative platform — specifically built for video. Where Sora is a single feature (text-to-video), Runway is a full toolkit: generate video from text, generate video from images, edit existing video with AI, remove backgrounds, change what is in a scene, slow down footage, and much more.

It is used by professional filmmakers and hobbyists alike. Available at runwayml.com.

Runway vs Sora — the key difference

Sora generates video from scratch based on your text. Runway does that too — but it also lets you take existing video and transform it with AI: remove a background, change the weather, age or de-age a face, swap one object for another, or animate a still photograph into video. For professional creative work, Runway’s editing and transformation capabilities are often more useful than raw generation.

Who made Runway?

Runway was founded in 2018 by Cristóbal Valenzuela, Alejandro Matamala, and Anastasis Germanidis, while they were students at NYU’s Tisch School of the Arts. It is headquartered in New York. By 2024, Runway had raised over $236 million and was valued at over $1.5 billion.

Runway is notable for its deep roots in the creative and film community — it was not built by researchers trying to commercialise AI, but by artists who wanted better tools for their own work. This origin shapes the product’s focus on professional quality and creative control.

The history of Runway

2018–2020: The research platform

Early Runway was focused on making research machine learning models accessible to artists and designers — a no-code interface for running models that would otherwise require Python expertise. This positioned Runway as a bridge between AI research and creative practice.

2021–2022: Stable Diffusion and the creative AI explosion

Runway became one of the platforms hosting Stable Diffusion models. When the open-source image AI movement exploded in 2022, Runway was well-positioned to offer it through a professional interface.

Gen-1 — February 2023

Runway’s Gen-1 model could transform existing video — applying the style of one video to another, changing environments, and modifying visual elements. It was the first high-quality AI tool for video transformation rather than generation from scratch.

Gen-2 — March 2023

Gen-2 added text-to-video generation. Users could now generate short video clips from text prompts, from images, or from a combination of both. The results were rough by later standards, but the capability itself was groundbreaking.

Gen-3 Alpha — June 2024

Gen-3 Alpha was a significant quality leap — more cinematic, more coherent over time, better character motion. It was trained specifically on data designed to produce “high-fidelity, consistent, and controllable” results. Runway positioned Gen-3 as professional-grade, and major studios and agencies began using it for commercial production.

2025–2026: Industry adoption

Runway became standard tooling for many video production workflows. The platform added more precise camera controls, better character consistency, and the Act-One feature — which allowed facial performance capture and transfer. Feature films and advertisements credited Runway AI in their production credits.

Runway in practice

Runway rewards users who understand cinematic language — camera movements, lighting descriptions, composition terms. The more precisely you describe the visual behaviour you want, the better the results.

1. Cinematic establishing shot
Slow aerial drone shot descending over [location description], golden hour lighting, long shadows, cinematic colour grading, smooth motion, [describe key visual elements], no people visible, suitable as a film opening shot
2. Animate a product image
[Upload product image] Animate this product with a gentle slow rotation, soft studio light source moving slightly, subtle depth-of-field breathing, professional product video feel, 4–6 seconds, loop-ready
3. Atmospheric scene for content
Close-up of [subject — raindrops on a window / candle flame / coffee being poured / flowers in wind], macro lens feel, shallow depth of field, soft natural light, slow motion, peaceful and meditative mood, suitable for social media or background video
4. Logo animation concept
[Upload logo image] Animate this logo appearing from [describe effect — dissolving particles / drawing itself / emerging from light / assembling from shapes], dark background, 3–4 seconds, elegant and professional, suitable as a video intro
5. Style transfer on existing footage
[Upload existing video clip] Transform this footage to look like [target style — a 1970s film / an anime scene / a watercolour painting / a noir film], maintain the motion and composition but completely change the visual aesthetic

Gen-3 architecture: consistency and control

Runway’s Gen-3 model is a video diffusion transformer trained on what Runway describes as a proprietary dataset designed specifically for high-fidelity, temporally consistent video generation. The architecture addresses the primary challenge of video generation: temporal coherence — ensuring that subjects, lighting, and scene geometry remain consistent across frames.

Runway’s approach to temporal consistency involves conditioning the generation process on multi-frame representations rather than single frames, and training with objectives that explicitly penalise temporal incoherence in the generated sequences. The specific architecture is not publicly detailed in peer-reviewed papers.
