Text-to-Video with Gen-3 Alpha

Gen-3 Alpha is Runway’s flagship model for generating video from text descriptions.

Writing Video Prompts

Effective video prompts include:

  1. Subject: What’s in the scene
  2. Action: What’s happening
  3. Setting: Where it takes place
  4. Camera movement: How the camera moves
  5. Mood/Style: Visual atmosphere

Example prompt:


A golden retriever running through a sunlit meadow of wildflowers, slow motion, cinematic camera tracking shot, warm summer light, shallow depth of field, film grain, 4K quality

Camera Control Keywords

Keyword Effect
Tracking shot Camera follows subject
Dolly in/out Camera moves toward/away
Pan left/right Camera rotates horizontally
Tilt up/down Camera rotates vertically
Crane shot Camera rises/lowers
Static shot Camera doesn’t move
Handheld Slight natural shake
Aerial/drone Overhead perspective

Style Keywords

  • Cinematic: Film-like quality with bokeh and color grading
  • Documentary: Natural, observational style
  • Slow motion: Reduced playback speed with smooth motion
  • Time-lapse: Accelerated time passage
  • Vintage/retro: Film grain, muted colors
  • Noir: High contrast, dramatic shadows

Image-to-Video

Transform still images into animated video clips:

How It Works

  1. Upload a reference image
  2. Add a text prompt describing the desired motion
  3. Gen-3 Alpha animates the image while maintaining visual consistency

Best Practices

  • Use high-resolution input images (1080p+)
  • Describe specific motions: “the woman turns her head and smiles”
  • Keep prompts focused on movement, not appearance (the image handles that)
  • Simple, natural motions work better than complex actions

Use Cases

  • Animate product photos for ads
  • Bring illustrations and concept art to life
  • Create dynamic social media content from static images
  • Generate B-roll from stock photos

Motion Brush

Motion Brush gives you precise control over which parts of your image move and how.

Using Motion Brush

  1. Upload an image or use a generated frame
  2. Select the Motion Brush tool
  3. Paint over the area you want to animate
  4. Set the motion direction and intensity with brush parameters
  5. Generate the video

Motion Brush Controls

  • Horizontal: Move left or right
  • Vertical: Move up or down
  • Proximity: Move toward or away from camera
  • Ambient: Subtle natural movement (like wind or breathing)

Tips

  • Paint precise masks for targeted motion
  • Use ambient motion for backgrounds (clouds, water, foliage)
  • Combine directional motion for complex movements
  • Keep at least one area static for visual anchoring

Advanced Video Editing Tools

Green Screen (Background Removal)

Remove backgrounds from video clips in seconds:

  1. Upload your video
  2. Click Green Screen
  3. Runway automatically detects and removes the background
  4. Export with transparent background or replace with a new one

Inpainting (Video)

Remove or replace objects in video:

  1. Upload a video clip
  2. Mask the object you want to remove
  3. Runway fills in the area naturally across all frames
  4. Maintains temporal consistency (no flickering)

Super Slow Motion

Create smooth slow-motion from any video:

  1. Upload a regular-speed video
  2. Select Super Slow Motion
  3. Choose the slowdown factor (2x, 4x, 8x)
  4. AI-generated frames are interpolated for smooth playback

Color Grade (AI)

Apply cinematic color grading:

  1. Upload your video
  2. Describe the desired look: “warm sunset tones” or “teal and orange cinematic”
  3. Runway applies AI-powered color correction

Workflow: Creating a Short Film Scene

Here’s a practical workflow for creating a polished scene:

Step 1: Plan Your Shot

Describe the scene, camera movement, and mood in detail before generating.

Step 2: Generate Multiple Takes

Create 3-5 variations of the same prompt. Each generation produces slightly different results.

Step 3: Select the Best Take

Review all generations and choose the one closest to your vision.

Step 4: Extend the Clip

Use “Extend” to add more seconds to your chosen clip. Each extension continues the motion naturally.

Step 5: Apply Motion Brush (Optional)

If specific elements need adjustment, use Motion Brush for fine control.

Step 6: Post-Process

  • Upscale to 4K if needed
  • Apply color grading
  • Export at your desired format

Step 7: Edit Together

Download clips and edit in your preferred video editor (Premiere Pro, DaVinci Resolve, etc.) or use Runway’s built-in timeline editor.

Custom Model Training

Train Gen-3 on your own visual style:

  1. Prepare training data: 10-30 high-quality images or video clips
  2. Create a training job: Upload your data and set parameters
  3. Train: Takes 1-4 hours depending on dataset size
  4. Use your model: Generate video in your custom visual style

Best for:

  • Consistent brand aesthetics across campaigns
  • Specific animation styles
  • Character consistency in multi-scene projects

Tips for Professional Results

  1. Be specific about camera movement: “Slow dolly in on the subject’s face” works better than “zoom in”
  2. Include lighting descriptions: “Soft diffused morning light” or “harsh overhead fluorescent”
  3. Specify the mood: “Melancholic,” “euphoric,” “tense” helps guide the generation
  4. Generate in batches: Create multiple versions and pick the best
  5. Use image-to-video for consistency: Generate a perfect still frame first, then animate it
  6. Keep it simple: One clear action per clip works better than complex scenes
  7. Extend wisely: Shorter initial clips (5s) extend more reliably than longer ones

FAQ

How long can Runway videos be?

Individual generations are 5 or 10 seconds. You can extend clips by generating additional segments that continue from the last frame. In practice, you can create clips of 30+ seconds through multiple extensions.

Is the video quality good enough for professional use?

Gen-3 Alpha produces 1080p video that’s suitable for social media, marketing materials, and creative projects. For broadcast or film, it works well as concept visualization, previz, or supplementary footage. Quality continues to improve with each model update.

Can I use Runway videos commercially?

Yes, paid plan subscribers retain commercial rights to their generated content. The free tier has watermarks and may have usage restrictions. Always check current terms for your specific use case.

How do credits work?

Credits are consumed based on the feature used and generation settings. A standard 5-second Gen-3 clip costs approximately 50 credits. Higher resolutions and longer durations cost more. Unused credits do not roll over on monthly plans.

What input formats are supported?

Runway accepts most common image formats (PNG, JPEG, WebP) and video formats (MP4, MOV, WebM). For best results with image-to-video, use high-resolution PNGs with the subject clearly visible.
