Tips for Better Results
- Prompt Detail: Describe lighting, camera movement, and atmosphere for better cinematic results.
- Audio Sync: Enabling audio works best when the prompt includes sound-producing elements (e.g., “thunderstorm”, “crowded street”).
- Consistency: Use a fixed
seedvalue if you want to tweak a prompt while keeping the general composition similar.
