How to Use Runway Gen-3 Alpha
Go from a still image or a written prompt to a finished Runway Gen-3 Alpha clip in three steps.
Runway Gen-3 Alpha Features
From Act One character performance to the Extend tool and Lip Sync, these are the capabilities Runway Gen-3 Alpha brings to AI video.
Multi-Modal Cinematic Output
Trained on video and image data, it handles Text to Video, Image to Video and Text to Image, with Motion Brush and Director Mode for art direction.
Act One Character Animation
Act One turns still character images into realistic, consistent facial movements and expressions, trained on facial animation data and mocap.
Video Extender for Longer Clips
Extend lengthens AI video in 5- or 10-second steps, up to three times, adding content from the final frame with a prompt for the new scene.
High-Fidelity Consistency and Realistic Physics
Next to Gen-2, output is more consistent and fluid, handling walking, running and jumping without glitches, and renders about 2x faster.
Advanced Temporal Controls
Layered prompts spanning several scenes and temporal ideas become smooth transitions from text alone, with keyframing-level control over timing.
Lifelike People and Lip Sync Audio
Human subjects are hard to tell from real people, and Lip Sync matches a typed script, recorded voice or audio upload to the character's mouth.
Runway Gen-3 Alpha — FAQ
Common questions about Runway Gen-3 Alpha, its credits, clip length and how to try it.
What is Runway Gen-3 Alpha and how does it differ from Gen-2?
Runway Gen-3 Alpha is Runway's latest AI video model. Alongside Lip Sync, it pushes past Gen-2 with sharper visuals and motion that reads as real.
Should I pick Turbo or the standard model?
Turbo is the speed-and-budget pick: it renders far quicker and burns fewer credits per second, while the standard model tends to return steadier, more dependable results.
How many credits does Gen-3 Alpha cost and what plans are available?
Expect 10 credits for every second of footage, so 100 credits for a 10-second clip, while Turbo halves that. Plans range from a 125-credit free tier to a Pro tier with 2250 monthly credits.
What is the maximum clip length and output resolution?
Clips top out at 10 seconds in 720p, and Extend can be applied three times to take a single video to roughly 40 seconds. More resolution options are promised later.
How can I try Gen-3 Alpha for free, and can developers use it through an API?
You can sign up for the free Basic plan on Runway or run the model free on this platform. Runway Gen-3 Alpha itself is not currently exposed through an API, although other supported Runway models are.
What can Gen-3 Alpha be used to create?
Anything from adverts and tutorials to short entertainment pieces, plus animation-style character performances and video-to-video restyling of existing footage.
