# Identify the show

Danmaku and posters both depend on knowing **what this is**. Get this right and the rest is easy.

## Automatic

On scan or add-to-library, the file name is used to guess:

- Which show
- Which episode

Then Fanmu looks it up on **Bangumi** for title, poster, and episode number.

## If the guess is wrong

The item is marked **unmatched**.

Nothing is deleted. Playback still works. You can leave it, or bind it by hand.

## Fix it by hand

Open the item:

1. Search for the show on Bangumi
2. Pick the right one
3. Confirm

You can re-scrape after binding to refresh posters and metadata.

## Why Bangumi

Bangumi has solid anime data and a real API. Not Douban, not TMDB.

If a niche title is missing there, you can only hand-edit the name, and danmaku may not match. Use [local XML danmaku](/en/guide/danmaku) as fallback.

## Common cases

| Case | What to do |
|------|------------|
| Name like `VCB-Studio][BanG Dream! Ave Mujica][01][1080p][x265_FLAC].mkv` | Usually auto-matched |
| Name like `video.mp4` | Search manually |
| Matched the wrong show | Rebind |
| OVA / special / movie | Episode number may be off; fix it |
