# Watch and danmaku

Open a file and you are on the player page.

## Playback

It is a web player. Play/pause, seek, volume, fullscreen are all there.

Leave halfway and progress is kept.

## Where danmaku comes from

Same idea as DanDanPlay: **one episode, one danmaku pool**.

1. You open a video
2. The system knows which show and episode it is (or you identified it earlier)
3. It asks the danmaku network for that episode
4. Danmaku floats over the video

So a 720P from one group and a 1080P from another, once matched to the same episode, share the same danmaku.

## No danmaku?

- **Unmatched**: [identify the show](/en/guide/scrape) first
- **Network down**: video still plays, just silent of danmaku. Retry later
- **Prefer a local file**: import an XML

### Import XML danmaku

On the player or the [Danmaku settings](#danmaku-settings) page, import a `.xml` danmaku file (the kind exported from Bilibili).

A video and a same-named danmaku file in one folder is also picked up.

## Danmaku settings

The **Settings** page's Danmaku section lets you set:

- On or off by default
- Opacity (lower it if it blocks the picture)
- Density (how many at once on screen)

You can also toggle while watching.

## A note on content

Danmaku comes from a public pool. If something bothers you, turn it off. Fanmu does not edit danmaku text.
