# Veo 3.1 — Text-to-Video

> Generate cinema-grade 4K video with native audio using Google DeepMind's Veo 3.1 in ComfyUI — available in Standard and Fast tiers.

Veo 3.1 is Google DeepMind's flagship text-to-video model, delivering cinema-grade 4K video with synchronized native audio. Available in **Standard** (full quality) and **Fast** (optimized speed) tiers, it supports detailed scene direction, camera movement, and visual style control.

## Key capabilities

* **Cinema-grade 4K video** — Generates 4K resolution video with crisp detail, natural lighting, and realistic physics.
* **Native audio sync** — Video output includes synchronized audio, eliminating the need for post-production alignment.
* **Text-to-video generation** — Create high-quality video directly from text prompts with full creative control.
* **Optimized Fast tier** — A faster inference variant that trades slight quality for significantly reduced generation time, ideal for iteration and draft production.

> 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
>
> **Cloud users**
>
> * [Cloud](https://cloud.comfy.org) will update after ComfyUI stable release.
