# 流外广告：如何创建流外广告活动
Outstream 广告是一种展示视频广告的原创且无缝的方式。它不是将视频放在特定的视频播放器中，而是在用户浏览网站时播放，广告位进入视口后便展开。如果用户继续滚动，视频广告会隐藏，但当其再次滚动回到可见位置时，会从用户离开时的同一位置继续播放。
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。本教程将说明如何创建 Outstream 广告。
## 如何创建 Outstream 活动
在创建广告活动的第 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以 Outstream 为投放目标。
如果您想将 Outstream 设为投放目标 **仅**，则需要在“区域类型”部分取消选择其他推送格式：
Outstream 视频始终以 **横屏**播放，因此请确保您的视频为横向或方形模式。Outstream 的创意要求与其他任何视频格式相同：您可以在以下位置了解更多视频广告规格要求： [广告格式页面](/exoclick-docs/ad-formats.md#in-stream-video-vast) ，详见本说明文档。
Outstream 广告活动可采用 CPC、CPM 和 **CPV**，这是一种仅适用于视频格式的付费模式。CPV 代表每次观看成本，意味着您将为广告格式产生的每次观看付费（一次观看在以下情况下生成： **10 秒** 视频广告播放的）。请注意，曝光仅统计实际视频播放的秒数：当 Outstream 广告被隐藏时，这些秒数不计入观看次数。
其余设置的选择方式与其他任何广告活动类似。您可以在以下位置找到我们各项定向设置的详细说明： [本说明文档中的主广告主部分](/advertisers/campaigns/creating-a-campaign/create-campaign-step1.md)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
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 optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
