remotion-captions

规定 Remotion 中字幕的 JSON 格式与必需字段，确保兼容与同步。

帮你把视频字幕统一成 Remotion 能识别的 JSON 格式，包含文字、开始/结束时间、timestampMs 和置信度等字段。遇到要把自动转写或外部字幕导入 Remotion、保证与视频帧严格对齐时会用到。特别之处是强制使用 Remotion 的 Caption 类型，保证兼容性和时间轴同步，方便后续渲染和调试。

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;
};
```
