WAN LoRA Collection v2.2 - Image-to-Video (I2V) Adapters (FP8)

A curated collection of specialized LoRA adapters for the WAN (Wangfuyun Animate) video generation model, focusing on camera control, lighting effects, and action animation for image-to-video (I2V) generation.

Model Description

This repository contains 6 specialized LoRA adapters designed to enhance WAN video generation capabilities for image-to-video workflows:

• Camera Control LoRAs : 4 models for precise camera movement control (arc shots, drone perspective, earth zoom-out, rotation)
• Lighting LoRAs : 1 model for cinematic lens flare effects
• Action LoRAs : 1 model for facial animation control (wink action)

These LoRAs are optimized for FP8 precision models and provide fine-grained control over video generation parameters while maintaining high quality and performance.

Model Specifications

Technical Details

• Format : SafeTensors (secure, memory-efficient binary format)
• Precision : FP8-compatible (optimized for FP8 base models)
• Architecture : LoRA (Low-Rank Adaptation) adapters
• Rank : Rank-16 for most models (efficient parameter count)
• Compatibility : WAN/AnimateLCM-SVD-xt FP8 base models
• Model Variants : I2V-optimized (image-to-video conditioning)

LoRA Strength Guidelines

• Camera Control LoRAs : Recommended strength 0.6-0.8 (higher for stronger camera movement)
• Lighting LoRAs : Recommended strength 0.4-0.6 (lower for subtle effects)
• Action LoRAs : Recommended strength 0.7-0.9 (higher for clear facial animation)

Combination Guidelines

• Camera + Lighting : Safe to combine (reduce camera to 0.6-0.7, lighting to 0.4-0.5)
• Multiple Camera LoRAs : Not recommended (conflicting motion vectors)
• Action + Camera : Can combine for animated portraits with camera movement
• Earth Zoom + Lighting : Excellent for dramatic establishing shots

Performance Tips

1. LoRA Selection : Use 1-2 LoRAs maximum per generation to avoid conflicts
2. Strength Tuning : Start at recommended strength and adjust ±0.1 based on desired intensity
3. Camera Movement : Use one camera LoRA at a time for consistent, smooth motion
4. Lighting Effects : Keep lighting LoRA strength lower (0.4-0.5) for natural-looking enhancement
5. Action Animation : Use action LoRAs with close-up portrait images for best results
6. FP8 Optimization : These LoRAs are specifically tuned for FP8 inference (2x faster than FP16)
7. Frame Count : Use 16-24 frames for action animations, 24-48 frames for camera movements
8. Guidance Scale : Use 7.0-8.5 for I2V (higher values increase prompt adherence)

Optimization Recommendations

# Enable memory-efficient attention
pipe.enable_attention_slicing()
pipe.enable_vae_slicing()

# Use FP16 for intermediate calculations (FP8 for weights)
pipe.unet.to(dtype=torch.float16)
pipe.vae.to(dtype=torch.float16)

# Enable xformers for faster attention (requires xformers package)
try:
    pipe.enable_xformers_memory_efficient_attention()
except:
    print("xformers not available, using default attention")

# Reduce VRAM usage for longer videos
pipe.enable_sequential_cpu_offload()  # For <12GB VRAM systems

Troubleshooting

Issue : Camera movement too strong or jittery

• Solution : Reduce LoRA strength to 0.5-0.6, increase num_inference_steps to 30-35

Issue : Lighting effects too subtle or invisible

• Solution : Increase LoRA strength to 0.6-0.7, use prompts with specific lighting keywords

Issue : Action animation not visible or too exaggerated

• Solution : Adjust strength (0.7-0.9 range), ensure image is close-up portrait, use clear action prompt

Issue : Out of memory errors

• Solution : Enable CPU offloading, reduce num_frames, use only one LoRA at a time
