WAN 2.5 FP8 Image-to-Video LoRA Collection

This repository contains Low-Rank Adaptation (LoRA) models for the WAN 2.5 image-to-video generation system in FP8 precision format. These LoRAs provide specialized enhancements for camera control, lighting adjustment, motion control, and quality improvement in generated videos from static images.

Model Description

WAN 2.5 Image-to-Video LoRAs are adapter models that enhance the base WAN 2.5 model for animating static images into dynamic videos. These LoRAs provide specialized capabilities:

Camera Control LoRAs: Precise control over camera movements, angles, and transitions in animated scenes
Motion Control LoRAs: Natural object and character motion within the scene
Lighting LoRAs: Enhanced lighting conditions, cinematic effects, and mood adjustment
Quality Enhancement LoRAs: Improved temporal coherence, detail preservation, and visual fidelity
Style LoRAs: Artistic motion styles and aesthetic modifications

FP8 Precision: These LoRAs use 8-bit floating point format for:

~50% reduced memory usage compared to FP16
Faster inference with minimal quality loss
Efficient deployment on consumer GPUs

Usage Examples

Basic LoRA Loading with Diffusers

python

from diffusers import DiffusionPipeline
import torch

# Load base WAN 2.5 model
pipe = DiffusionPipeline.from_pretrained(
    "E:/huggingface/wan25-base",  # Path to base WAN model
    torch_dtype=torch.float8_e4m3fn,
    variant="fp8"
)

# Load camera control LoRA
pipe.load_lora_weights(
    "E:/huggingface/wan25-fp8-loras/loras/wan/camera",
    weight_name="camera_pan.safetensors",
    adapter_name="camera_pan"
)

# Set LoRA scale (0.0 to 1.0)
pipe.set_adapters(["camera_pan"], adapter_weights=[0.8])

# Generate video with camera pan effect
prompt = "A sweeping pan across a mountain landscape at sunset"
video = pipe(
    prompt=prompt,
    num_frames=120,
    height=720,
    width=1280,
    guidance_scale=7.5,
    num_inference_steps=50
).frames[0]

# Save video
import imageio
imageio.mimsave("output_video.mp4", video, fps=24)

Multiple LoRA Combination

python

# Load multiple LoRAs for combined effects
pipe.load_lora_weights(
    "E:/huggingface/wan25-fp8-loras/loras/wan/camera",
    weight_name="camera_pan.safetensors",
    adapter_name="camera"
)

pipe.load_lora_weights(
    "E:/huggingface/wan25-fp8-loras/loras/wan/lighting",
    weight_name="lighting_cinematic.safetensors",
    adapter_name="lighting"
)

pipe.load_lora_weights(
    "E:/huggingface/wan25-fp8-loras/loras/wan/quality",
    weight_name="quality_detail.safetensors",
    adapter_name="quality"
)

# Set weights for each LoRA
pipe.set_adapters(
    ["camera", "lighting", "quality"],
    adapter_weights=[0.8, 0.7, 0.6]
)

# Generate with combined effects
prompt = "Cinematic camera pan through a detailed futuristic cityscape"
video = pipe(prompt=prompt, num_frames=120).frames[0]

Dynamic LoRA Weight Adjustment

python

# Gradually increase LoRA effect during generation
def generate_with_dynamic_lora(pipe, prompt, lora_schedule):
    """
    lora_schedule: dict mapping frame ranges to LoRA weights
    Example: {(0, 40): 0.3, (40, 80): 0.7, (80, 120): 0.5}
    """
    frames = []
    for frame_range, weight in lora_schedule.items():
        start, end = frame_range
        pipe.set_adapters(["camera_pan"], adapter_weights=[weight])

        frame_chunk = pipe(
            prompt=prompt,
            num_frames=end - start,
            guidance_scale=7.5
        ).frames[0]

        frames.extend(frame_chunk)

    return frames

# Example: Start subtle, peak in middle, fade out
schedule = {
    (0, 40): 0.3,    # Subtle effect
    (40, 80): 0.8,   # Strong effect
    (80, 120): 0.4   # Fade out
}

video = generate_with_dynamic_lora(pipe, "Mountain landscape pan", schedule)

Performance Tips and Optimization

LoRA Weight Tuning

Start Low: Begin with weights around 0.5 and adjust upward
Test Combinations: Some LoRAs may conflict at high weights
Per-Category Guidelines:
- Camera: 0.7-1.0 for strong movements
- Lighting: 0.5-0.8 for natural appearance
- Quality: 0.4-0.7 for subtle enhancement
- Style: 0.6-1.0 depending on desired intensity

Memory Optimization

python

# Enable memory-efficient attention
pipe.enable_xformers_memory_efficient_attention()

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

# Reduce batch size for multiple LoRAs
pipe.enable_sequential_cpu_offload()

Inference Speed

Single LoRA: ~5-10% slowdown vs base model
2-3 LoRAs: ~10-20% slowdown
4+ LoRAs: ~20-30% slowdown
Tip: Merge compatible LoRAs offline for faster inference

Quality vs Speed Trade-offs

python

# Faster inference (reduced quality)
video = pipe(
    prompt=prompt,
    num_inference_steps=30,  # Reduced from 50
    guidance_scale=6.0       # Reduced from 7.5
)

# Higher quality (slower)
video = pipe(
    prompt=prompt,
    num_inference_steps=75,  # Increased
    guidance_scale=8.5       # Increased
)

LoRA Management Best Practices

Unload Unused LoRAs: Free memory between generations

pipe.unload_lora_weights()
Cache Frequently Used: Keep common LoRAs loaded
Test Individually: Verify each LoRA before combining
Document Weights: Track successful weight combinations
Version Control: Note which LoRAs work well together
