1. Tutorial Introduction

This tutorial uses a single RTX 4090 card as the resource, and the video generation takes about 10 minutes. It is recommended to use a GPU with 80GB of memory for better generation quality.

HunyuanCustom, released by Tencent's Hunyuan team on May 9, 2025, is a multimodal customized video generation framework. It's a multimodal, conditionally controllable generative model built upon the Hunyuan Video generation framework, centered on topic consistency. It supports generating topic-consistent videos with text, images, audio, and video inputs. Leveraging HunyuanCustom's multimodal capabilities, numerous downstream tasks can be accomplished. For example, by acquiring multiple images as input, HunyuanCustom can facilitate virtual human advertising and virtual makeup try-ons. Related research papers are available.
