Hunyuan Video has emerged as the leading open-source AI video generation model, offering capabilities that rival OpenAI's Sora but with free and accessible implementation. Known for its exceptional ability to create smooth, coherent videos from text prompts, HunyuanVideo can generate everything from realistic human movements to complex scene transitions with remarkable accuracy.
ComfyUI 0.3.8 and higher versions now officially integrates HunyuanVideo, making this powerful video generation technology accessible through its node-based interface. While local installation of ComfyUI can be challenging and HunyuanVideo requires substantial GPU resources, cloud platforms like MimicPC have already updated their pre-installed ComfyUI, offering immediate access with their high-performance GPU options.
In this guide, we'll walk you through using the official HunyuanVideo example workflows in ComfyUI, enabling you to create professional-quality AI videos. We'll explore the essential nodes and settings needed to harness this groundbreaking technology.
