Why Use Runway AI for Avatars?

  Log in to access the dashboard and start creating.

Step 2: Prepare Your Reference Materials

You need a reference image or video for your avatar.

• Static Avatars: Use a clear, high-resolution image (e.g., a photo or a DALL-E-generated image).
• Dynamic Avatars: Use a 10-second video of someone speaking or performing actions like waving.
• Tips: Ensure good lighting and a frontal view for best results. Save files as PNG, JPEG, or MP4.

Step 3: Create Your Avatar with Gen-4 References

Navigate to the “Gen-4 References” tool in Runway AI’s dashboard.

• Upload 1–3 reference images or a short video.
• Write a text prompt describing your avatar (e.g., “a friendly cartoon character in a blue jacket”).
• Click “Generate” to create your avatar video.
• Review the output and regenerate if needed for better quality.
  This tool ensures your avatar looks consistent across different scenes.

Step 4: Animate Your Avatar with Expressive Characters

Use the “Expressive Characters” tool (part of Act-One in Gen-3, likely updated for Gen-4 in 2025) to add movements.

• Go to “Generative Session” and select “Act-One” from the toolbar.
• Upload a driving performance video (e.g., someone speaking your narration script).
• Select your avatar image or video as the character.
• Adjust settings to fine-tune expressions or lip-sync accuracy.
• Click “Generate” to create an animated avatar that mimics the driving video’s movements.
  This step makes your avatar talk or perform actions naturally.

Step 5: Customize Your Avatar for Brand Style

Match your avatar to your YouTube channel’s brand.

• Colors: Choose clothing or background colors that align with your brand’s palette.
• Backgrounds: Use Gen-4 References to set a scene (e.g., “a modern studio” or “a colorful cartoon world”).
• Actions: For intros, make your avatar wave or say a greeting. For narration, ensure lip-sync matches your script.
• Consistency: Use the same avatar style across videos for brand recognition.
• Style Presets: If available, select presets like “Pixar-style” or “realistic” to match your aesthetic.

Step 6: Export and Use Your Avatar

Export your avatar video for YouTube.

• Click “Export” in Runway AI.
• Choose MP4 format and select quality (e.g., 1080p).
• Download the video and add it to your YouTube intro or narration.
• Use editing software like CapCut to combine with other video elements if needed.

Tips for Success

• High-Quality Inputs: Use clear, well-lit images or videos for better results.
• Specific Prompts: Write detailed prompts (e.g., “a smiling astronaut in a neon city”).
• Experiment: Try different styles or actions to find the best fit.
• Lip-Sync: Use a clear driving video for accurate narration movements.
• Test Outputs: Preview and regenerate if the avatar’s look or movements need tweaking.

Troubleshooting

• Blurry Outputs: Use higher-resolution inputs or adjust settings.
• Poor Lip-Sync: Ensure the driving video has clear speech and a frontal view.
• Slow Processing: Use Google Chrome for faster performance.
