The Disc You Know You Own and Cannot Find
It's Saturday evening. You want to rewatch something specific — a film you've seen twice, own on Blu-ray, and can picture the case sitting on the shelf somewhere. Twenty minutes later you're still looking, because the shelf has no system, the cases aren't alphabetical, and some discs are in the cabinet in the other room. You give up and stream something you care about less.
That's the failure mode this template is built to prevent: not missing a film, but wasting the evening failing to retrieve what you already have.
Nazev, Title, and the Bilingual Library Problem
Czech collectors who source films internationally keep two title fields for a reason. Title holds the original release title — the one that appears on the international cut, the import disc, the ČSFD entry. Nazev holds the Czech distribution title, which for older films can be entirely unrecognizable from the original. Alien becomes Vetřelec. Blade Runner stays Blade Runner but The Thing becomes Věc. If your library is shelved by Czech title but you're searching by director or international title, you need both fields or you'll miss your own collection.
The Csfd field stores the ČSFD database ID as an integer — a direct link into the Czech film database, the primary reference for Czech and Slovak cinephiles. This is not a URL field and not a text note. It's a typed integer that can be used to open the corresponding ČSFD entry directly. A library of five hundred films with ČSFD IDs is a library that's cross-referenced to cast biographies, press reviews, user ratings, and streaming availability — without copying any of that data into Memento.
Medium, Zvuk, Titulky: The Playback Spec That Saves an Evening
The three fields that determine whether a film can actually be watched the way you want to watch it are Medium, Zvuk (audio format), and Titulky (subtitles). These fields exist because physical media ownership is not binary.
Medium distinguishes between DVD, Blu-ray, 4K UHD, digital file, VHS transfer, and whatever else the collection contains. A film that exists in the database as a DVD copy may also have been acquired as a 4K file — or vice versa. Without the medium field, you don't know which version you're reaching for until you have the case in your hand.
Zvuk records the audio specification: DTS-HD MA 5.1, Dolby Atmos, Czech dub, original mono, Czech stereo dub only. This matters when you're setting up for a proper screening versus casual viewing, and it matters critically when the film has a Czech dub that doesn't include the original audio track — an oversight common in older domestic releases.
Titulky captures subtitle availability and language. For foreign-language films in a Czech collection, whether Czech subtitles are hardcoded, soft-coded, absent, or only available in the theatrical cut is operational information. A film that arrived without Czech subtitles may not be watchable by everyone in the household.
Together, Medium/Zvuk/Titulky form the playback specification for each entry. Sort by medium and you can pull every 4K disc instantly. Filter by Zvuk for Atmos-capable films before a calibration session. Query Titulky to find everything in the collection that lacks Czech subs before a viewing evening with guests.
Rezie and Hudba: The Director's Cut That Tells You Why
Rezie (director) is a standard catalog field — every film database has it. The interesting field is Hudba (music/composer). Most personal film databases don't track composers because streaming interfaces don't surface that data. A physical collection built by someone who pays attention to scores — Ennio Morricone, Bernard Herrmann, Riz Ortolani, Jan Kačer — is a collection where filtering by composer becomes a valid retrieval method.
When you want to rewatch something with a specific sonic texture, filtering by composer is faster than trying to remember title names.
Zhlednuto and the Unwatched Queue
The Zhlednuto boolean (literally "watched/viewed") is the collection's backlog indicator. A collection that has grown through gift-giving, secondhand purchases, and bulk acquisitions from estate sales will have a significant percentage of unwatched entries. Filtering for Zhlednuto = false produces the actual unwatched queue — not a streaming recommendation algorithm, but a list of physical objects sitting in your own home waiting for attention.
The flag boolean serves a separate purpose: marking films for a specific action — loan tracking, planned rewatches, items to sell, whatever the user's current workflow requires. One collector uses flag for "needs better version"; another uses it for "promised to a friend." The field is intentionally generic.
Obr stores cover art — the physical sleeve scan or official poster image. At catalogue scale, cover art turns a list into a browsable visual library. The image appears in card or gallery view, and at a hundred entries, the difference between browsing artwork and scrolling text is the difference between remembering what you own and forgetting.
Cas records runtime. Useful for the specific decision of whether there's enough evening left to start a film. Two hours and forty minutes is a different commitment than ninety-three minutes, and knowing before you press play means you don't start something you can't finish.
