Video and audio open in a player. It streams the file in byte ranges, so you can jump to any point in a long recording without waiting for the rest to download.

| Kind | Extensions |
| --- | --- |
| Video | `.mp4`, `.m4v`, `.mov`, `.webm` |
| Audio | `.mp3`, `.m4a`, `.wav`, `.ogg`, `.oga`, `.opus`, `.flac`, `.aac` |

```bash
jalco-drop demo.mp4
jalco-drop -e 7d voice-memo.m4a
```

Which files play depends on the browser opening them. MP4 with H.264 video plays in every browser. Others, such as HEVC `.mov` recordings from an iPhone, may not, so convert them first:

```bash
ffmpeg -i recording.mov -c:v libx264 -c:a aac recording.mp4
```

## Link previews

A video drop's link preview carries the video, so it can play inline in chat apps that support it.

## In markdown

A [markdown drop](/file-types/markdown#html-in-markdown) can embed a video or audio file with a `<video>` or `<audio>` tag, pointing at its raw link.
