# 云端渲染

云端渲染允许用户通过云服务器处理所有渲染任务，从而保证渲染性能与本地设备规格无关且稳定。

## 渲染时机

云端渲染在触发播放时开始。某些参数（如 AI-pitch）会在对应编辑工具激活时进行预渲染。 

## 渲染状态

未渲染的片段在时间标尺内以灰色大括号标示。

正在渲染的片段会闪烁。

## 渲染范围

{% tabs %}
{% tab title="Verse25 及更高版本" %}
模型会动态检测渲染范围。若只修改小区域，则仅重新渲染被修改的区域。
{% endtab %}

{% tab title="Verse24 及更低版本" %}
模型以片段方式逐段渲染。每段长度大致对应于一个乐句（当乐句超过15秒时会被拆分）。当某一段或与之相连的段发生变更时，该段将被重新渲染。
{% endtab %}
{% endtabs %}
