# 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 H.264 代理文件，您可以在浏览器和应用中查看。代理文件会按比例缩放到适合 1080p（1920×1080，竖屏视频为 1080×1920）以内；更小的视频则保持原始尺寸。代理文件会以一致的质量进行编码：30 fps 及以下的视频最高码率为 6,000 kbps，60 fps 及以下为 8,000 kbps，60 fps 以上为 12,000 kbps。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。

### 预览 LUT

在查看视频时，您可以应用颜色查找表（LUT）进行预览：

1. 点击 **应用 LUT** 播放器控件中的按钮。
2. 选择 **上传 LUT…** 并从您的电脑中选择一个 `.cube` 文件。

要移除它，请打开同一菜单并选择 **清除 LUT**。LUT 只会更改您在播放器中的预览。它不会更改文件或其代理文件，其他团队成员也不会看到它。

### 常见问题

<details>

<summary>我是否必须等待代理文件生成后，别人才能下载我的资产？</summary>

不会。只要您的文件一上传，与该文件共享的其他人就会立即获得访问权限。您可以在我们的代理和 AI 任务在后台运行时进行评论、下载并查看元数据。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浏览。

</details>

<details>

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

不会。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重新上传。这在您预计要在网络连接较差的情况下使用 ShadeFS 挂载时很有用。在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。

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