slow motion, film grain, 35mm lens, shallow depth of field

Prompt structure:

• Subject — who/what is in the scene

• Setting — where and when
• Style — cinematic language (shot type, lens, lighting)
• Mood — atmosphere and feel

    headers={
        "Authorization": f"Bearer {API_KEY}",
        "X-Runway-Version": "2024-11-06"

Runway vs Competitors

Limitations & Considerations

• Credit system can be costly for heavy users
• 10-second maximum for standard generations
• Consistency challenges — generating the same character across clips is difficult
• Prompt sensitivity — results vary significantly with prompt wording
• Copyright questions — training data and output ownership still evolving

The Future of AI Video

Runway is building toward:

• Longer video generation (minutes, not seconds)
• Consistent characters across scenes
• Real-time generation capabilities
• Full film pipeline integration

The convergence of AI video tools is reshaping what’s possible for solo creators and small studios — the playing field between indie and Hollywood is narrowing rapidly.
