Introduction
This workflow leverages the advanced capabilities of the Hunyuan FastVideo model, integrated with ComfyUI, to achieve rapid and high-quality video generation. By combining optimized precision formats, temporal coherence techniques, and modular design, it ensures smooth, visually appealing outputs. Key features include FP8 precision, efficient latent processing, and adaptive scheduling, allowing users to generate videos in under two minutes while maintaining impressive quality.
Hunyuan FastVideo (Optimized for Speed)
FastHunyuan is an accelerated HunyuanVideo model. It can sample high quality videos with 6 diffusion steps. That brings around 8X speed up compared to the original HunyuanVideo with 50 steps.
The Hunyuan FastVideo is specifically designed to accelerate video synthesis. With its FP8 precision (fp8_e4m3fn encoding) and lightweight architecture, it minimizes computational overhead, delivering fast results without compromising the visual fidelity.

Workflow Overview
How to use this workflow?
Step 1: Input and Model Selection
Load the Hunyuan FastVideo model (fp8_e4m3fn.safetensors) for optimized video synthesis.
Step 2: Input Text Prompts
Use the DualCLIPLoader to input text prompts that guide the video generation process.
Step 3: Sampling and Decoding
Set up the BasicScheduler with a sampling step count of 15 for fast yet high-quality results.
Step 4: Export Final Output
Export the generated video in H.264 format (720p, 24fps) using the Video Combine node.
