Your Master Catalog, backed by the crowd

Share & compare catalog puts a copy of your Master Catalog's identity data on z-keeper.com — for two reasons: a safety net if you ever lose everything, and a second opinion from every other collector who uploaded theirs.

That's the whole list. No video files, no personal information — and nobody ever sees your name. Each upload replaces your previous one.

Runtime is the tell: online listings are minute-rounded — the pool's are exact.

Upload once, and the pool opens

Contributing is what grants the view: your titles unlock everyone else's filenames, sizes and runtimes for those same films and episodes — matched by TMDB or TVDB id, never by name.

Compare: does your copy run as long as everyone else's?

For every title you share with the pool, your runtime meets the consensus — the runtime most other catalogs agree on. Seconds don't lie: a wrong match or a broken rip shows up as minutes.

Match — you agree with the consensus.  Almost — a few minutes off: most likely a different edition (that Blade Runner is a Final Cut).  Outlier — nobody shares your runtime: check the match. A 16-minute-short movie is usually the wrong movie in the file's clothes — here, the 1984 Dune sitting in a file the pool knows as the 2021 one.
Two quieter verdicts: Thin data (too few catalogs hold it to judge) and Only you (you're the first — someone has to be).
Episodes are where this shines. Rip a disc carrying several episodes and it's genuinely easy to number them wrong — and because a season's episodes all run about the same length, TMDB's minute-rounded runtimes can't tell E03 from E04: both are “43 min”. Look at that last row. Your file is 1:26 away from the 1,043 catalogs holding the real S01E03 — a gap only to-the-second runtimes can show. That's E04 wearing E03's number.

Same show, same season, same length — only the seconds know which episode you really have.

Click a row: see the whole room

Every row expands to the community's full runtime distribution — each bar one distinct runtime, ×N catalogs holding it, with file-verified counts. The amber dial decides how far from consensus still counts as "Almost".

Every runtime is colored by its distance from the consensus — Match · Almost · Outlier. The gold ◄ you marks which one is yours.
The Almost band: consensus ± 3 minutes
Inside the band = Almost (an edition, probably). Beyond it = Outlier. Drag the knob — the verdict follows.
(903 verified) means 903 of those runtimes were measured from the actual file, to the second — the rest are player-reported values, rounded to the minute. The Verified only filter drops the rounded ones. Turn it on when checking episodes: where every episode runs "about 43 minutes", only to-the-second records can disagree.

Drag it and every verdict re-classifies live — your report, your strictness.

Turn verdicts into a to-do list

Flag clears your approval on a suspect title — one row at a time, or every Almost / every Outlier at once. Nothing is changed or deleted; the title simply goes back in the review queue.

Flagged titles also surface in the Filesystem page's Unapproved matches view — your to-do list, wherever you like to work.

The pool never decides for you — it only tells you where to look.
