How to Use Runway AI (Video Generation)
If you want to learn how to use Runway AI for video generation, you're looking at the platform with the most creative controls in the space. While Sora generates clips from a text prompt and hopes for the best, Runway gives you tools to direct the output: Motion Brush to control how specific elements move, Director Mode for precise camera choreography, and keyframing for shot-by-shot planning.
Runway's Gen-4.5 (released December 2025) currently holds the top score on the Artificial Analysis Text-to-Video benchmark at 1,247 Elo, ahead of both Sora 2 and Google Veo 3.1. The company raised $315 million in February 2026 at a $5.3 billion valuation, so the platform isn't going anywhere.
What Runway Offers in 2026
Runway has grown from a video generation tool into a multi-model creative platform. The current lineup:
- Gen-4.5: Flagship model. Native 1080p, native audio, best physics and prompt adherence
- Gen-4 / Gen-4 Turbo: Cheaper alternatives (12 and 5 credits/sec vs Gen-4.5's 25)
- Aleph: In-context video editing. Change lighting, style, mood, or backgrounds on existing clips
- Act-Two: Performance capture. Head, face, body, and hand tracking applied to characters
- Lip Sync: Synchronize audio to animate photos/video, up to 45 seconds, multi-face support
- Google Veo 3/3.1: Integrated directly into Runway's platform alongside their own models
You also get text-to-video, image-to-video, video-to-video style transfer, Motion Brush, camera controls, upscaling to 4K, and a node-based Workflows system for chaining models into automated pipelines.
Getting Started
Step 1Create Your Account
Go to runwayml.com and sign up. The free tier includes 125 one-time credits (they never renew but don't expire). That's enough for a few short clips to test the platform. Free-tier output is watermarked and capped at 720p.
Step 2Choose Your Model and Mode
From the dashboard:
- Text to Video with Gen-4.5 for the highest quality generation from a text prompt
- Image to Video for animating a starting frame (more consistent results than text-only)
- Motion Brush for painting motion directions onto specific areas of an image
- Gen-4 Turbo for fast, cheaper iteration when you're experimenting
Step 3Generate and Iterate
Write your prompt or set up Motion Brush directions, then generate. Gen-4.5 outputs at native 1080p, 24 fps. You can upscale to 4K after generation (costs additional credits).
Credit usage per second of video:
| Model | Credits/second |
|---|---|
| Gen-4.5 | 25 |
| Gen-4 (Aleph) | 15 |
| Gen-4 | 12 |
| Gen-4 Turbo | 5 |
| Act-Two | 5 |
A 5-second Gen-4.5 clip costs 125 credits. The same clip on Gen-4 Turbo costs 25 credits. Use Turbo for experimentation, Gen-4.5 for final renders.

Gen-4.5: What Changed
Gen-4.5 is a meaningful step up from Gen-4. The differences that matter:
Physics feel real. Objects carry weight. Liquids behave like liquids. Cloth drapes and wrinkles correctly. Collisions are physically plausible. The "floaty" quality of earlier models is mostly gone.
Prompt adherence is much better. Gen-4.5 handles complex, sequenced instructions — you can describe camera choreography, atmospheric changes, and specific event timing in a single prompt and get something close to what you asked for.
Native 1080p. Previous models rendered at 720p and required upscaling. Gen-4.5 generates at 1080p natively.
Native audio. Built-in sound design synchronized to video. No need for separate audio tools.
Motion Brush
Motion Brush is what makes Runway different from every other video generator. Instead of describing motion in text, you paint it.
How it works:
- Upload an image or use a generated frame
- Select Motion Brush
- Paint over elements you want to move
- Set direction and speed for each brushed area
- Add a text prompt that aligns with your motion directions
You can create up to 5 independent motion zones, each moving differently. Clouds left, river right, bird upward, leaves downward — all in one frame.
Tips:
- Align your text prompt with brush directions. Conflicting instructions produce artifacts.
- Start at low brush strength (30-40%) and increase if needed.
- Add "crisp motion" to your prompt to reduce motion blur.
Director Mode
Director Mode replaced the simpler camera controls from earlier versions. It recognizes specific cinematography terminology and separates camera movement from subject movement.
You can specify pan, tilt, zoom, dolly, and roll with fractional precision. "Slow dolly in" produces a different result than "push in" or "zoom in." That predictability is why video professionals pick Runway over tools that guess at camera movement from text descriptions.
Workflows
Runway introduced a node-based Workflows system in late 2025 that lets you chain multiple models into automated pipelines. Generate with Gen-4.5, auto-enhance, apply style transformations, export in multiple formats — all as a single automated process.
Workflows can be published as shareable Apps within a workspace. This is mostly useful for production teams that need repeatable processes.
Runway Pricing
| Plan | Monthly | Annual (per month) | Credits/month | Key Features |
|---|---|---|---|---|
| Free | $0 | — | 125 (one-time) | 720p, watermarked, 3 projects |
| Standard | $15 | $12 | 625 | All models, 4K upscale, no watermark |
| Pro | $35 | $28 | 2,250 | Custom voice creation for lip sync |
| Unlimited | $95 | $76 | 2,250 + relaxed unlimited | Up to 10 users per workspace |
Credits don't roll over. On the Standard plan (625 credits), you get roughly 25 seconds of Gen-4.5 video, 52 seconds of Gen-4, or 125 seconds of Gen-4 Turbo per month.
The Standard plan at $12/month (annual) is a reasonable entry point. Unlimited at $76/month makes sense for teams generating video daily — the relaxed queue gives unlimited generations at lower priority.
Runway vs. Sora vs. Veo 3.1
| Runway Gen-4.5 | Sora 2 | Google Veo 3.1 | |
|---|---|---|---|
| Benchmark | 1,247 Elo (highest) | 1,206 Elo | 1,226 Elo |
| Native resolution | 1080p (4K upscale) | 1080p | 4K native |

| Native audio | Yes (Gen-4.5) | Yes | Yes (best quality) |
| Entry price | $12/mo | $20/mo | Free via Gemini |
| Creative control | Highest (Motion Brush, Director Mode) | Good (storyboard mode) | Basic (prompt-based) |
Choose Runway when you need precise control over camera, motion, and style. When consistency across multiple clips matters. When you want access to multiple model engines (including Google Veo) on one platform.
Choose Sora when storyboard-based narrative content is the goal, or when you want longer clips (25 seconds) from a single generation.
Choose Veo 3.1 when you need 4K native resolution or the best audio synchronization quality.
Most professional creators use 2-3 of these platforms and pick whichever fits each shot best. For more on Sora specifically, see our Sora AI guide.
Getting Better at Runway
The learning curve is steeper than Sora or Pika, but the control you gain is worth it.
Start with Image-to-Video. More predictable than text-to-video because the model has a visual reference. Upload a photo, add minimal motion, learn how the model interprets instructions.
Then Motion Brush on simple scenes. Single elements first — flowing water, moving clouds, a turning head. Master single-zone motion before attempting multi-zone compositions.
Then Director Mode. Combine camera movements with scene descriptions. Learn which cinematography terms produce which results on Runway specifically.
Then complex compositions. Multi-motion scenes, style transfers with Aleph, performance capture with Act-Two. Study the Runway showcase gallery and reverse-engineer techniques.
The single best habit: change one variable at a time between generations. Changing multiple settings at once makes it impossible to learn what actually improved the result.

FAQ
Is Runway AI free to use?
Runway offers a free tier with 125 one-time credits (they don't renew monthly). Free output is watermarked and capped at 720p, with no access to Gen-4 video generation. Paid plans start at $12/month (annual) or $15/month with 625 monthly credits and access to all models.
How long can Runway AI videos be?
Individual generated clips are 5-10 seconds. You can extend sequences by generating additional clips and assembling them in Runway's built-in editor. Gen-3 Alpha clips can be extended up to 40 seconds total. For longer content, generate shot by shot.
What is Motion Brush in Runway?
Motion Brush lets you paint motion directions directly onto specific areas of an image. You can create up to 5 independent motion zones, each with its own direction and speed. It's Runway's main differentiator — no other platform offers this level of fine-grained motion control.
Is Runway better than Sora?
They solve different problems. Runway (Gen-4.5) tops the benchmarks, offers the most creative controls, and costs less ($12/month vs $20/month). Sora generates longer clips (up to 25 seconds via storyboard mode) and handles cinematic realism well. Most professionals use both.
Can I use Runway videos commercially?
Yes. All paid plans include commercial usage rights. The free tier has restrictions on commercial use. Standard plan or above for business, advertising, or client work.
