# 流外：如何创建流外广告活动
Outstream 广告是一种原创且无缝的视频广告展示方式。它不是将视频放置在特定的视频播放器中，而是在用户浏览网站时播放；当广告区域进入视口时，广告便会展开。如果用户继续滚动，视频广告将会隐藏，但当其再次向上滚动回到原位置时，它会从用户离开时的位置继续播放。
Outstream 提供 [多项优势](https://www.exoclick.com/advertisers-6-reasons-you-should-be-using-outstream-video/) 相较于标准横幅格式。在本教程中，我们将说明如何创建 Outstream 广告。
## 如何创建 Outstream 活动
在您的活动设置第 1 步中，选择 **视频** 作为您的广告格式。Outstream 是一种 **区域类型**，这意味着所有视频活动默认都会定向到 Outstream。
如果您想仅将 Outstream **单独**作为定向目标，那么您需要在区域类型部分取消选择其他推送格式：
Outstream 视频始终以 **横向**播放，因此请确保您的视频为横屏或方形模式。Outstream 的素材要求与其他任何视频格式相同：您可以在本说明文档的 [广告格式页面](/exoclick-docs/zh/guang-gao-ge-shi.md#in-stream-video-vast) 中了解更多视频广告规格要求。
Outstream 活动可以使用 CPC、CPM 和 **CPV**，这是视频格式专属的付费模式。CPV 代表每次观看成本，意味着您将为该广告格式产生的每次观看付费（一次观看是在 **10 秒** 的视频广告播放后生成）。请注意，观看次数只计算实际视频播放的秒数：当 Outstream 广告隐藏时，这些秒数不会计入观看次数。
其余设置的选择方式与您在其他活动中所做的相同。您可以在本说明文档的 [广告主主要部分](/advertisers/zh/guang-gao-xi-lie/chuang-jian-guang-gao-xi-lie/create-campaign-step1.md)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.exoclick.com/tutorials/zh/jiao-cheng/guang-gao-zhu-jiao-cheng/how-to-set-up-outstream-campaign.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
