Usage Tips

Query Optimization: Use descriptive keywords that match LoRA specializations (e.g., "rotating", "exploding", "kissing")
Resolution Choice: Use 480p for faster generation and lower cost, 720p for higher quality
LoRA Scale: Default 0.7 works well for most cases. Increase for stronger effects, decrease for subtler results
Frame Count: 81 frames is optimal for most animations. Increase up to 100 for longer videos
Image Requirements: Input images should be clear, well-lit, and properly composed for best results
