What Is FusionX?
FusionX is a merged model that combines the power of several individual LoRAs:
- Causvid – Speeds up generation and improves coherence.
- MovieGen – Adds cinematic aesthetics and image quality, especially for videos with human subjects.
- AccVid – Enhances motion quality and reduces generation time.
- Detail and Realism Enhancers – Custom LoRAs from the creator that boost fine details and realism.
How to Use FusionX in ComfyUI
Fusion X is designed to work with ComfyUI and is especially easy to use with the RunPod platform, where you can rent GPUs affordably to run powerful models.
✅ Getting Started:
- Choose the FusionX merged model or load the LoRA version into your current workflow.
- Use standard image-to-video or text-to-video nodes depending on your use case.
- Adjust generation steps, sampling, and strength settings based on your GPU and performance needs.
What Makes Fusion X Stand Out?
Research and recent implementations show that Fusion X builds upon WAN 2.1 (14B), blending multiple specialized components to deliver both visual quality and performance:
✦ CausVid for smoother, more coherent motion.
✦ AccVideo to align frames temporally and accelerate rendering.
✦ MoviiGen 1.1 enhances cinematic lighting and softness.
✦ MPS Reward LoRA boosts motion realism and detail.
✦ Additional custom LoRAs to enrich textures and subtle visual fidelity.
This setup brings filmmaking-grade video creation under your fingertips—even within just 6 steps. It’s a significant leap forward
ComfyUI & Workflow Integration
ComfyUI users are in luck—FusionX is tightly integrated:
✦ It works smoothly in both Text-to-Video (T2V) and Image-to-Video (I2V) workflows.
✦ Popular configurations recommend:
- CFG = 1
- Shift values: 1 for 1024×576, 2 for 1080×720
- Samplers like uni_pc or beta for optimal motion and quality
✦ VACE integration enables powerful capabilities like frame control, pose manipulation, object replacement, and more—all powered by Fusion X as the base model. Combined with Normalized Attention Guidance (NAG), you gain precise dual-prompt control.
