Introduction to Runway Act-One
Runway Act-One is a powerful feature in the Runway Gen-3 Alpha suite. This tool enables creators to transform static images into dynamic film-quality scenes. Whether you’re just starting out or you’re an experienced AI artist, this section will guide you through the basics of setting up and using Runway Act-One.
Getting Started: Driving Videos in Runway Act-One
A driving video is essential for Runway Act-One to animate your chosen character. Follow these tips to ensure success:
- Proper Lighting: Keep your video well-lit to avoid shadows.
- Centered and Forward-Facing: Your face should remain steady and centered in the frame.
- Minimal Movement: Avoid large hand or arm movements, as these are not yet supported.
- Clear Expressions: Ensure your facial expressions are distinct and exaggerated enough for the AI to interpret them.
- Simple Backgrounds: A clean and distraction-free background works best.
We recommend watching the video for detailed guidance, starting at 00:49, to perfect your driving video setup.
Once your video is ready, click the “Try it now” button on the Runway homepage and upload your video in the provided section.
Uploading Character Images for Animation
In Runway Act-One, you can upload your own images or select from the platform’s character library, which includes photorealistic, animated, and illustrated options.
Best Practices for Character Images
- Choose images with front-facing faces and visible shoulders.
- Avoid profile shots; opt for medium or close-up shots for the best results.
- Ensure the character’s posture complements your intended animation style.
Tip: The angle of your uploaded image directly affects the animation. For instance, a character looking down will maintain that posture in the final video.

Advanced Prompt Crafting for AI Filmmaking
Creating cinematic-quality visuals with AI requires precision in your text-to-image prompts. Detailed prompts help the AI better understand your vision, allowing you to achieve results that align with your creative goals. Here’s how you can craft and refine prompts for exceptional outcomes:
The Importance of Precision in Prompts
From testing over 20,000 prompts while developing my Prompt Toolkit, I’ve discovered that the more detailed your descriptions, the closer the AI will come to realizing your vision. This approach eliminates guesswork and produces refined results.
- Example Prompt for Sci-Fi Scenes: “Futuristic science lab filled with large cylinders of liquid containing various bizarre and exotic alien creatures.”
- This precise description clearly defines the environment, objects, and overall style, enabling the AI to create compelling, lifelike imagery.
Leveraging Genre-Specific Inspiration
The Prompt Toolkit includes genre-specific inspiration pages for themes like horror, sci-fi, and fantasy. These pages offer ready-to-use prompts and structured keyword combinations to spark your creativity and streamline the process.
- Example Prompt from Horror Genre: “An alien with a grisly brain covered by translucent gelatinous skin, layered with putrescent slime.”
- This vivid prompt showcases how specificity can bring unique and realistic elements to life, adding depth to your creations.
The Final Result
Using these inspiration pages, you can explore creative possibilities while mastering the art of crafting precise, impactful prompts. By combining detailed descriptions and genre-specific elements, your AI filmmaking projects will stand out with professional quality.
