WAN 2.5 FP16 LoRA Collection

High-quality LoRA adapters for WAN 2.5 video generation models in FP16 precision for enhanced control and quality improvements.

Model Description

This repository contains LoRA (Low-Rank Adaptation) adapters specifically designed for the WAN 2.5 video generation model. These adapters enable fine-grained control over various aspects of video generation including camera movements, lighting conditions, and overall quality enhancements without requiring full model retraining.

Key Features:

• Camera Control LoRAs: Precise control over camera movements (pan, tilt, zoom, dolly)
• Lighting Enhancement: Dynamic lighting adjustment and atmospheric control
• Quality Improvements: Enhanced detail, reduced artifacts, improved temporal consistency
• FP16 Precision: Balance between quality and performance
• Modular Design: Mix and match LoRAs for combined effects

Use Cases:

• Cinematic video generation with professional camera movements
• Lighting-controlled scene generation
• Quality enhancement for existing generations
• Style transfer and artistic effects
• Motion control and temporal consistency improvements

Performance Tips and Optimization

LoRA Strength Guidelines

• Camera Control: 0.6-0.9 for strong effects, 0.3-0.5 for subtle movements
• Lighting: 0.5-0.7 for natural adjustments, 0.7-0.9 for dramatic effects
• Quality: 0.4-0.6 for enhancement without over-processing

Memory Optimization

# Enable memory-efficient attention
pipe.enable_xformers_memory_efficient_attention()

# Use CPU offloading for limited VRAM
pipe.enable_sequential_cpu_offload()

# Reduce precision for inference (if needed)
pipe.vae.to(dtype=torch.float16)
pipe.unet.to(dtype=torch.float16)

Batch Processing

# Process multiple prompts efficiently
prompts = [
    "Scene 1 with camera pan",
    "Scene 2 with dramatic lighting",
    "Scene 3 with enhanced details"
]

videos = pipe(
    prompt=prompts,
    num_frames=48,
    height=512,
    width=768,
    num_inference_steps=30,
    guidance_scale=7.5
).frames

for i, video in enumerate(videos):
    export_to_video(video, f"batch_output_{i}.mp4", fps=24)

Quality vs Speed Trade-offs

• Fast: 20-25 steps, lower resolution (512x512), single LoRA
• Balanced: 30-35 steps, medium resolution (768x512), 1-2 LoRAs
• High Quality: 40-50 steps, high resolution (1024x576), multiple LoRAs

Recommended Combinations

1. Cinematic: Camera dolly + Dramatic lighting + Detail enhancement
2. Natural: Camera pan + Natural lighting + Temporal consistency
3. Artistic: Camera zoom + Color temperature + Quality enhancement
