# 代理生成和复杂预览

当您的资产上传到 Shade 后，我们的系统会生成 1080p、约 6000K 比特率的 H264 代理文件，您可以在浏览器和应用中查看。这些代理文件可供打算使用代理文件而非原始文件工作的团队成员下载。

### 常见问题

<details>

<summary>在有人可以下载我的资产之前，我必须等待代理文件生成吗？</summary>

不需要。只要您的文件上传完成，任何被分享该文件的人都可以访问它。在我们的代理和 AI 任务于后台运行时，您可以进行评论、下载和查看元数据。Shade 还会为您的视频生成预览图，处理完成后即可在资产页面上拖动查看。

<details>

<summary>代理文件可以通过 ShadeFS 挂载访问吗？</summary>

不可以。ShadeFS 挂载会将原始文件流式传输到您的电脑。代理文件可以从应用中下载，然后再通过应用或挂载上传回来。这在您预计会在网络连接较差的情况下使用 ShadeFS 挂载时很有用。等您拥有更强的连接后，原始媒体可以重新链接，您的时间线也可以导出。

## 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://academy.shade.inc/shade-academy/shade-academy-zh/su-cai/markdown.md?ask=<question>&goal=<endgoal>
```

`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.

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.
