# 视频轨道

## 概览

视频轨道是一条特殊的全局轨道，用于在同一时间线中将画面与音乐和音效对齐。

你可以通过轨道标题栏，以及混音器中的静音、独奏和音量控制来控制视频音频播放。

要显示或隐藏视频轨道，请点击轨道列表标题栏中的视频轨道按钮。

## 创建视频轨道

你可以通过以下方式创建视频轨道：

* 将视频文件拖到画布上。
* 将视频文件导入工程，然后放到一条空轨道上。

如果视频包含内嵌音频，你可以将该音频分离出来，并在音频轨上单独管理。

## 视频片段管理

在视频轨道上，你可以：

* 分离或重新附加音频。
* 替换视频。
* 调整视频音量，并对音频应用淡入和淡出。

双击视频片段可打开视频监视器进行预览。

## 使用 Video Composer

Video Composer 是一款 AI 工具，可帮助你在 ACE Studio 中为视频创建音乐和音效。它会分析视频，生成匹配的音频，并将结果作为可编辑片段放置到时间线上。

## 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.acestudio.ai/docs/product-wiki-zh/gong-cheng/arrangement-in-canvas/video-track.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.
