Runway Gen-3 Alpha in Three Steps
Take a written prompt or a single still and walk away with a finished clip — three quick steps, no editing suite required.
What Runway Gen-3 Alpha Can Do
Character performance, clip extension, lip sync and faster rendering — here is what this model actually puts in your hands.
One Model, Three Modes
Trained on both video and image data, it covers Text to Video, Image to Video and Text to Image, with Motion Brush and Director Mode for art direction.
Act One Facial Performance
Act One converts still portraits into consistent, lifelike expressions and head movement, drawing on facial animation data and motion capture.
Extend Tool for Longer Runs
Extend grows a clip in 5- or 10-second increments, up to three times, continuing from the last frame with a prompt describing the next beat.
Steadier Frames, Convincing Physics
Compared with Gen-2, results hold together better and flow more smoothly — walking, running and jumping land without glitches, at roughly double the render speed.
Temporal Control Across Scenes
Prompts that span several scenes and beats resolve into seamless transitions from text alone, giving keyframe-level command over timing.
Realistic Faces and Lip Sync
Human subjects are nearly indistinguishable from real footage, and Lip Sync aligns a typed script, recorded voice or uploaded audio to the character's mouth.
Runway Gen-3 Alpha: Your Questions Answered
Straight answers on credits, clip length, model choice and the fastest way to test this AI video model for free.
What exactly is Runway Gen-3 Alpha, and how is it different from Gen-2?
It is Runway's newest AI video model. Beyond adding Lip Sync, it moves past Gen-2 with crisper visuals and motion that reads as genuine.
Turbo or the standard model — which should I choose?
Choose Turbo when speed and budget matter most: it renders much faster and spends fewer credits per second. The standard model tends to deliver steadier, more predictable output.
What does Gen-3 Alpha cost in credits, and which plans exist?
Budget 10 credits per second of footage — 100 credits for a 10-second clip — while Turbo uses half. Plans run from a 125-credit free tier up to Pro with 2250 credits monthly.
How long can a clip be, and at what resolution?
Output stops at 10 seconds at 720p, though Extend can be applied three times to stretch one video to roughly 40 seconds. Additional resolutions are planned.
Can I test Gen-3 Alpha for free, and is there an API?
Sign up for Runway's free Basic plan, or run Runway Gen-3 Alpha at no cost on this platform. The model is not currently offered through an API, though other Runway models are supported.
What kinds of videos can I make with it?
Ads, tutorials and short entertainment pieces, plus animated character performances and video-to-video restyling of footage you already have.
