混元视频 1.5 ComfyUI 教程

了解如何使用混元视频 1.5，一个轻量级的 8.3B 参数模型，可在消费级 GPU 上生成高质量视频

混元视频 1.5是由腾讯混元团队开发的轻量级 8.3B 参数模型。它可在消费级 GPU（24GB 显存）上提供旗舰级质量的视频生成，大幅降低了使用门槛，同时不影响质量。

​

模型亮点

• 小巧强大：在消费级硬件上运行的同时，提供与大型模型相当的 SOTA 性能。
• 多功能生成：支持高质量的文本生成视频和图像生成视频（5-10秒），具有出色的一致性。
• 精确控制：对镜头运动、物理效果和情感表达有强大的指令遵循能力。
• 电影级质量：原生 720p 输出（可升级至 1080p），具有专业美学效果。
• 丰富功能：支持多种风格（写实、动漫、3D）和视频内文字渲染（中文/英文）。

Portable or self deployed users

Make sure your ComfyUI is updated.

• Download ComfyUI
• Update Guide

Workflows in this guide can be found in the Workflow Templates. If you can’t find them in the template, your ComfyUI may be outdated. (Desktop version’s update will delay sometime)

If nodes are missing when loading a workflow, possible reasons:

1. You are not using the latest ComfyUI version (Nightly version)
2. Some nodes failed to import at startup

Desktop or Cloud users

• The Desktop is base on ComfyUI stable release, it will auto-update when there is a new Desktop stable release available.
• Cloud will update after ComfyUI stable release.

So, if you find any core node missing in this document, it might be because the new core nodes have not yet been released in the latest stable version. Please wait for the next stable release.
