What is Runway Gen 4?

Runway Gen 4 is an advanced AI video model that excels at creating cinematic content with consistent characters and realistic motion. Unlike earlier models, Gen 4 maintains character appearance across frames and produces natural physics and movement. It's like having a film studio that can generate any scene while keeping your actors looking the same throughout.

Common use cases

  • Character videos: Consistent protagonists in narrative content
  • Brand mascots: Animated brand characters with personality
  • Music videos: Artistic sequences with recurring subjects
  • Short films: Narrative content with character continuity
  • Explainers: Educational content with consistent hosts
  • Social series: Multi-video content with same characters

Generate your video step by step

Start creating

STEP 2: Define character and action

Write a detailed prompt for consistent results:

  • Character description: Include specific details like age, clothing, hair, and features
  • Character action: Describe exactly what your character does
  • Setting details: Specify environment and background elements
  • Camera work: Include shot type and camera movement
  • Visual style: Add cinematic qualities and mood

STEP 3: Generate consistent video

Click "Generate" and Runway Gen 4 creates your video. The AI maintains character consistency while producing realistic motion and natural physics. Processing takes 60-90 seconds for high-fidelity output.

STEP 4: Review and refine

Check for character consistency and motion quality: Character inconsistent? Regenerate with more specific physical descriptions. Motion looks off? Adjust action descriptions and physics keywords.

  • Verify character looks the same throughout the entire video
  • Check that movement follows natural physics and looks realistic
  • Ensure cinematic quality matches professional standards

Tips for best results

💡 Be specific about characters

Detailed character descriptions produce better consistency. Instead of 'woman', try 'woman in her 30s with shoulder-length brown hair, wearing blue sweater and jeans'.

💡 Keep actions simple

Runway Gen 4 excels at focused actions. One clear movement like 'turning to look at camera' works better than complex multi-step actions.

💡 Use reference images

If generating multiple videos with the same character, keep detailed notes about their appearance. Consistent descriptions create consistent results.

💡 Plan for editing

Generate short clips that you can edit together. This gives you more control than trying to create one perfect long video.
