Metadata Explained

What is Metadata?

Metadata is information about a movie or TV show—everything except the actual video itself.

What Metadata Includes

  • Posters (vertical cover art)
  • Backdrops (horizontal background images)
  • Titles (official name)
  • Descriptions (plot summaries)
  • Cast & Crew (actors, directors, writers)
  • Release dates
  • Genres (Action, Comedy, Drama, etc.)
  • Ratings (IMDb scores, Rotten Tomatoes, etc.)
  • Runtime
  • Episode lists (for TV shows)
  • Season numbers
Note

Key point: Metadata is separate from streams. A movie can have beautiful metadata but no streams (or vice versa).


Why Metadata Matters

1. Aesthetic Appeal

Good metadata makes Stremio look polished:

  • Professional posters instead of blank squares
  • Accurate titles instead of file names
  • Proper episode organization

2. Discoverability

Metadata helps you find content:

  • Search by actor, director, or genre
  • Browse by rating or release year
  • Identify what you want to watch

3. Organization

Metadata keeps your library clean:

  • TV shows grouped by season/episode
  • Correct sorting (by title, date, etc.)
  • No duplicates with different names

4. Context

Metadata gives you information to decide:

  • Read plot summaries before committing
  • Check ratings and reviews
  • See cast and crew

How Metadata Works in Stremio

Metadata Add-ons

Stremio gets metadata from metadata add-ons (separate from stream add-ons).

Default metadata add-on:

  • Cinemeta (Stremio’s official metadata service)
  • Pre-installed
  • Provides metadata for most movies and TV shows

Other metadata add-ons:

  • TMDB (The Movie Database)
  • AIOMetadata-style add-ons (enhanced metadata with more sources)
  • Genre-specific add-ons (anime, documentaries, etc.)

How It Works

  1. You search for or select a title in Stremio
  2. Stremio asks metadata add-ons: “What info do you have for this title?”
  3. Metadata add-ons return posters, descriptions, cast, etc.
  4. Stremio displays the combined results
Tip

You can install multiple metadata add-ons. Stremio will use the first one that returns data for each field.


Common Metadata Problems

Problem: Wrong Poster or Backdrop

Cause:

  • Metadata add-on pulled incorrect data
  • Title has multiple versions (remakes, regional differences)
  • Add-on’s database is outdated

Fix: See Fix Wrong Posters/Titles


Problem: Missing Information

Cause:

  • Metadata add-on doesn’t have data for this title
  • Title is very new or obscure
  • Add-on is broken or offline

Fix:

  • Install additional metadata add-ons
  • Wait (data may be added later)
  • Manually search for the title using a different spelling

Problem: Duplicate Entries

Cause:

  • Multiple metadata add-ons providing the same title
  • Different spellings or regional variants

Fix:

  • Uninstall redundant metadata add-ons
  • Check your Library for duplicates and remove extras

Problem: Wrong Language

Cause:

  • Metadata add-on is set to a different language
  • No metadata available in your preferred language

Fix: See Language & Regional Settings


Metadata vs. Streams

Metadata and streams are provided by different add-ons.

AspectMetadata Add-onStream Add-on
ProvidesInfo (posters, descriptions)Playable video sources
ExamplesCinemeta, TMDBYouTube, OpenSubtitles, etc.
Legal statusAlways legal (just information)Varies (depends on source)
Required?Recommended (makes Stremio usable)Required (to watch anything)

You need both types:

  • Metadata add-ons to see what’s available and look pretty
  • Stream add-ons to actually watch content

Using metadata add-ons is 100% legal everywhere. They’re just pulling publicly available information from databases like IMDb, TMDB, etc.

No legal risk involved in:

  • Installing metadata add-ons
  • Browsing content via metadata
  • Organizing your library with metadata
Note

Metadata add-ons don’t provide streams, so they can’t be used to access copyrighted content illegally. They’re purely informational.


Best Practices

✅ DO:

  • Install at least one metadata add-on (Cinemeta is good for most users)
  • Try multiple metadata add-ons if you’re not satisfied with results
  • Keep metadata add-ons updated (uninstall/reinstall if they seem stale)
  • Use metadata to track content even if you watch elsewhere

❌ DON’T:

  • Install too many metadata add-ons (can cause conflicts or duplicates)
  • Expect perfect metadata for every title (some are obscure or new)
  • Confuse metadata with streams (different purposes)
