Tips for Better Results

  1. Clear, Descriptive Prompts: Use specific, detailed descriptions for better video quality
  2. Motion Description: Include details about camera movement and scene dynamics
  3. Negative Prompts: Use negative prompts to avoid unwanted elements like blur or distortion
  4. CFG Scale Tuning:
    • Lower values (0.3-0.5): More creative, less prompt adherence
    • Higher values (0.7-1.0): More prompt adherence, less creative variation
  5. Aspect Ratio Selection: Choose based on intended use (16:9 for landscape, 9:16 for mobile, 1:1 for social media)
