## Best Use Cases

- Film production — generate cinematic footage from screenplays and treatments.
- Commercials — create professional ad content directly from creative briefs.
- Music videos — generate visual sequences from lyrical descriptions.
- Premium social media — produce high-quality short-form video content.
- Film visualization — prototype scenes and camera movements before production.

## Pro Tips

- Write prompts like a screenplay — subject, action, setting, camera, lighting.
- Specify camera movements explicitly: 'slow dolly in', 'handheld tracking shot', 'aerial crane up'.
- Include temporal language: 'gradually', 'suddenly', 'the camera slowly reveals'.
- Use reference images (up to 9) for character and style consistency across clips.
- Start with 5s at 480p for fast iterations, then render final at 1080p or 4K.

## Notes

- Audio is generated natively by default — no need for separate audio tools.
- Duration range: 4-15 seconds (continuous selection).
- Supports up to 9 reference images, 3 reference videos, and 3 reference audios.
- Median generation time: approximately 252 seconds.
