Register Czech (locale detection, persisted preference, language menu) and add the Czech catalog: all 3,547 rows written as whole phrases with a video-editing glossary. A quality test (cs_quality.rs) checks placeholders, capitalisation, leftover English words, straight quotes and collisions, with an explicit list of justified exceptions.

Localization parity
Last reviewed: 2026-10-10 · Last updated: 2026-10-11 · Change: major (new file: per-language status measured from the catalogs; replaces ROADMAP.md's "Interface localization" section) · Target: Adobe Premiere Pro 2026 (26.5.2)
Per-language status of FilmCraft's interface. Premiere 26.5.2 ships 10 interface languages (the
installed bundle's .lproj folders): German, English, Spanish, French, Italian, Japanese, Korean,
Portuguese (Brazil), Russian, Simplified Chinese.
How it works
Edit ▸ Language (also Settings ▸ General, general.interfaceLanguage) switches the interface and
persists across restarts; System Language (the default) follows the OS's or browser's preferred
languages and falls back to English. Commands app.language.<english|japanese|spanish|portuguese|ukrainian|chinese|german|russian|french|czech>
are reachable over the control channel. One catalog per language,
crates/ui-egui/src/i18n/<code>.tsv (format in the header of es.tsv); UI code wraps strings in
tl!("…") / tlf!("…{name}", name), and registry names (effects and their parameters, settings,
commands, panels, workspaces, presets) are translated where they are drawn. Searches match the
displayed labels as well as English sources. Tests fail when a tl! literal, a menu label or a
registry name has no Spanish entry; zh-cn.tsv must also cover every tl! literal and menu
label; ja.tsv and fr.tsv have the same entries but are not yet required by tests (French must
cover the core menus and keep no entry without a Spanish one). Engine error messages, the
control channel, the CLI and MCP stay English.
Fonts come from craft-fonts (CRAFT_FONTS_DIR, all
official releases) or an installed system face; without one, switching to Japanese or Chinese is
refused with a message. Simplified Chinese is picked for zh, zh-CN, zh-SG, zh-Hans, not
Traditional locales. Ukrainian uses the bundled Cyrillic interface fonts. Vertical text in titles
is supported. The interface (egui) does not shape complex scripts or lay out right to left;
the title engine (crates/text, harfrust + bidi) does, but Arabic titles are reported broken (#395).
Status
Measured 2026-10-10 by counting entries in each catalog. The denominator is the union of all
catalogs' sources (3,498 strings); strings not yet wrapped in tl! and engine messages are
not in it, so real coverage is somewhat lower than shown. Estimates calibrated from #449 (Japanese,
whole interface, one PR) at ~4–8 h per language for the catalog plus tests.
| Language | Code | UI strings | Dialogs / tooltips / help | Script support | Native review | Status | To full |

| Other shipped: Ukrainian | uk | 351 (10.0%) | menus only | Cyrillic (bundled) | not recorded | menus only | 5–9 h |
Premiere also ships Italian and Russian, which we don't (6–10 h each).
Localization dimension: 5 of the 12 key languages near-complete (English, Spanish, Japanese,
Simplified Chinese, French), 1 menus-only, 6 none; against Premiere's 10 languages we cover 5 well
and 1 partly. ~35%, 150–230 h for all twelve to full plus Italian and Russian, of which the script
work (RTL and complex shaping in the egui interface) is the largest and least parallel part.
Every language needs native-speaker review (human).
Czech catalog quality
The 3,547 Czech rows were rewritten as complete phrases in batches from the English meanings, with French/German entries and Rust call sites consulted for ambiguous labels. This is an AI-assisted translation with a binding video-editing glossary, not yet proofread by a native speaker. Coverage measures lookup keys, not linguistic approval or a complete UI walkthrough. In particular, Bin is Přihrádka, Trash is Koš, Lift is Zvednout, Extract is Vyjmout s posunem, and Timeline is Časová osa. The original catalog header comments were preserved; their older glossary shorthand is superseded by these terms and the catalog rows.
i18n::cs_quality checks placeholders, capitalization, Czech quotation marks, ellipses, common
English leftovers, identical text and shared translations. Exact-key exceptions with reasons
are stored in crates/ui-egui/src/i18n/cs-quality-exceptions.json; a changed collision or an
unused exception fails the test. Identical strings include formats, brands, units and standard
Czech words whose spelling is the same as English (for example Text, Video, Export and Proxy).
Czech grammatical homographs a, to, by and SPDX OR are explicitly distinguished from
English leftovers. The maintainer-local plan/check_cs_catalog.py additionally checks raw TSV
escapes and compares comments, contexts, source keys and order against plan/cs-original.tsv.
It writes a report of every accepted exception; it does not generate translations.
The current catalog parser and formatter have no plural-variant selection, and none of the
other catalogs provide plural rows. Unused Czech plural-selector code was removed. The UI's
existing singular branches are retained; other counts use neutral wording such as
“Počet klipů: {n}”, valid for 0, 1, 2–4 and larger counts without a new runtime API.
Native review should concentrate on audio automation terms, Slip/Slide/Roll operations,
creative effect names, and the shared Subtitle key (caption format and graphics subtitle).
