## 透過 Agent 執行 Veo 3.1

- [OpenClaw](https://runapi.ai/zh-HK/openclaw-veo-3.1.md) — 使用 OpenClaw Agent 呼叫 Veo 3.1，RunAPI 工具提供可呼叫操作並自動輪詢工作。
- [Hermes Agent](https://runapi.ai/zh-HK/hermes-veo-3.1.md) — 使用 Hermes Agent 呼叫 Veo 3.1，以自然語言描述需求，Hermes 會選擇合適設定。


## 開始使用 Veo 3.1

1. **選擇模型** — 挑選符合輸出類型、品質門檻與延遲目標的模型與變體。
2. **設定** — 設定 RunAPI key，並在 coding workspace 安裝 model skill。
3. **開發** — 使用 skill 指引，在你的 app 內加入模型功能。
4. **接收** — 透過 task ID 查詢、在支援時串流，或處理 webhook callback。



## Veo 3.1 API 是甚麼？

Veo 3 is a frontier video generation model by Google DeepMind, notable for its native audio-video joint synthesis. Through RunAPI, it benefits from unified API access and shared billing across all Google models.

## 為何透過 RunAPI 使用 Veo 3.1 API

- **一個驗證，對應所有 provider** — 一組 RunAPI key 即可解鎖整個 catalog。無需分開帳戶，亦無需為每個整合輪換密鑰。
- **統一定價與計費** — 按次以 USD 收費，每月結算。失敗的生成不會收費。
- **內含 schema 的 skill** — 型別化 schema 與 setup 備註打包在 model skill 內，讓實作從正確契約開始。


## Veo 3.1 常見問題

### Does Veo 3.1 generate audio with the video?

Yes — Veo 3.1 natively synthesizes synchronized audio including dialogue, sound effects, and ambience in the same generation call.

### What resolution does Veo 3.1 output?

Native 1080p generation with upscaling support to 4K (3840×2160). Aspect ratios include 16:9 and 9:16.

### How long can generated clips be?

4, 6, or 8 seconds per generation. Scene Extension works once from a text-to-video result and cannot be chained.

### Are generated videos watermarked?

All Veo outputs include an invisible SynthID watermark embedded in the pixel data, which persists through compression and resizing.

### How is the audio generated?

Veo 3.1 generates native audio synchronized with the on-screen action, matching sound to the motion and events in the scene.

### 我應該先用邊個版本？

先選最平而且符合你質素要求的版本。大多數團隊會先用快速版本，之後再升級到 pro 用於正式生產。
