Tips for Better Results

  1. Detailed Prompts: More descriptive text yields better visuals
  2. Use First Frame for I2V: Provide a starting image for higher temporal consistency
  3. Seeds for Control: Use a fixed seed for reproducibility
  4. Camerafixed: Set true to keep perspective locked
  5. Resolution vs Cost: Higher resolutions take longer and may cost more
