Shelves full of discs and no idea what you own? The simplest way to learn how to catalog a movie collection is to give each title one record: a database match, your format and edition, and a shelf location.
This guide sits within the wider topic of film collecting for beginners, which covers the basics of starting and growing a home library.
| Item | Value |
|---|---|
| Metadata database used as the example | TMDB, API v3 |
| Catalogue resource types | Movie, television series, season/episode, person, image reference |
| Language request examples | en-US and pt-BR |
| Release event types | Premiere, theatrical, digital, physical |
| What an image reference contains | A file path plus a chosen size |
These details come from Emby’s learning page on TMDB metadata. Databases and software change over time, so check the source before you rely on the figures.
Why match each film to a database record?
A typed title is easy to get wrong. Spelling varies, remakes share names, and a film can carry a different title in each country. A database match gives every film a stable identity that your own notes can hang from.
TMDB, The Movie Database, is one such service. According to Emby’s page, it supplies catalogue data for movies, television and people, together with associated images. That makes it a convenient neutral example of how a catalogue is organised.
The same page points out that selecting the right match is more specific than pasting a numeric value into an unspecified field. In practice, this means you choose the correct record for the film rather than just storing a number.
What should you record for each film?
Database fields describe the film. Your own fields describe the copy on your shelf. Keep the two apart so a metadata refresh never overwrites your personal notes.
A practical set of personal fields looks like this:
- The matched database record for the film.
- Format: disc, tape or digital file.
- Edition or release name, as printed on the packaging.
- Audio and subtitle languages actually on the disc or file.
- Condition and any missing inserts.
- Shelf, box or folder location.
- Purchase notes, if you want them.
Editions deserve their own field because two copies of one film can differ a great deal. A separate explainer on what is a special edition dvd covers how those releases differ. Background on the history of vhs and home video helps explain why the same film appears on several formats.
How to catalog a movie collection around TMDB’s data structure
Emby’s page explains that TMDB’s API v3 documentation treats movies, television series, seasons and episodes, people and images as distinct resources. A movie is a movie record, a series is a series record, and a person is a credited person. Pictures sit beside these records as separate assets, so a poster never stands in for the film itself.
This matters for a film collector because the same printable number can point at different things. A movie lookup and a TV lookup using the same number should not be treated as the same entity relationship. If your collection mixes films with series boxsets, store which kind of record each match is.
How do languages, artwork and dates behave?
Three details trip people up when they first build a catalogue. Each comes down to the difference between the film and the way a database presents it.
Language of the description
TMDB documents language-region requests such as en-US and pt-BR. Those requests can change the descriptive text you get back. They do not change the film: according to Emby’s page, changing the metadata request language does not change the spoken language of the local video.
Translations may also be incomplete. The page notes that the documentation does not promise that every field is localized, so a title or overview may fall back to another language. Record the audio and subtitle languages of your own copy yourself.
Artwork
An image path is not the downloaded artwork. TMDB’s image documentation combines configuration information with an image’s file path and a chosen size. A smaller version is a derivative of the asset, not another film, so do not count it as a separate entry.
Release dates
TMDB provides release-date and certification information with release types such as premiere, theatrical, digital and physical. The single year shown in your library is a presentation of that richer information. Different valid dates for different countries or event types are not a sign that you matched the wrong film.
A simple cataloguing workflow
You can do the whole job with a spreadsheet or with media-library software that fetches metadata. The order of work matters more than the tool.
- Gather one shelf or box at a time so nothing is counted twice.
- Match each film to the correct database record, checking that it is a movie and not a series.
- Add your personal fields: format, edition, languages on the copy, condition and location.
- Note anything odd, such as a missing booklet or a disc with a different cover.
- Review the list against the shelf and fix mismatches before you move on.
Work in small batches. A short session on one shelf is easier to finish, and a consistent habit keeps the catalogue accurate as new titles arrive.
Frequently asked questions
Do I need special software to catalog a movie collection?
Show answer
No. A spreadsheet works if you keep the same columns for every film. Library software can fetch metadata from databases such as TMDB for you, but you still add your own fields for format, edition and location.
Why does my catalogue show a different release year from the box?
Show answer
Databases can hold several release events for one film, such as premiere, theatrical, digital and physical releases. According to Emby’s page, the year displayed is a presentation of that richer information, so a different year does not by itself mean a wrong match.
Does changing the metadata language change the film’s audio?
Show answer
No. Emby’s page states that changing the metadata request language does not change the spoken language of the local video. It affects the descriptive text only, and not every field is guaranteed to be translated.
Is a poster image the same as a film record?
Show answer
No. An image reference is a related asset, not the movie identifier itself. A smaller image variation is a derivative of the asset, not another catalogue film.
