## Before / After 对比

### 字幕处理效率对比

**Before**:

在没有此技能之前，开发者需要手动解析字幕文件、逐帧对齐时间戳、处理置信度数据，并编写大量自定义渲染逻辑。整个过程耗时且容易出错，尤其是处理长视频时，手动调整字幕位置和时间非常繁琐。

**After**:

使用该Skill后，开发者只需调用标准API即可一键生成、导入和显示字幕。此技能自动处理时间对齐和置信度，大幅减少编码工作量，字幕渲染准确率接近100%，视频制作效率提升数倍。

| Metric | Before | After | Change |

## Readme

All captions must be processed in JSON. The captions must use the [`Caption`](https://www.remotion.dev/docs/captions/caption.md) type which is the following:

```ts
import type { Caption } from "@remotion/captions";
```

This is the definition:

```ts
type Caption = {
  text: string;
  startMs: number;
  endMs: number;
  timestampMs: number | null;
  confidence: number | null;
};
```

## Generating captions

To transcribe video and audio files to generate captions, load the [transcribe-captions.md](transcribe-captions.md) file for more instructions.

## Displaying captions

To display captions in your video, load the [display-captions.md](display-captions.md) file for more instructions.

## Importing captions

To import captions from a .srt file, load the [import-srt-captions.md](import-srt-captions.md) file for more instructions.
