Tips for Better Results

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