Prompt Guidelines

Do

• Describe motion and action — “camera moves through forest”
• Specify mood — “peaceful,” “energetic,” “mysterious”
• Mention style — “cinematic,” “documentary”
• Use negative prompt when available — Exclude unwanted elements

Avoid

• Overly long prompts
• Conflicting style or motion
• Vague descriptions

Tips & Tricks

1. 480p + silent for tests — Lowest cost (~0.16 credits/5s).
2. Toggle audio — Turn off for drafts to save credits.
3. 1080p for final — Use 480p/720p to iterate, then 1080p.
4. Fixed camera — Use when you want stable, minimal motion.
5. Last frame — Guide the ending if you have a target image.
