Upstream added Korean and Italian while this branch added Czech; all three are kept (13 languages, Czech last) in settings, menus, the native menu and the i18n tables, with docs/attribution rows from both sides. Czech for the 15 strings added on main since (recent files, ripple delete head frame, 32-bit audio formats, browser/help texts, Korean font notice). Note: graphics_notice_ui::the_notice_follows_the_interface_language fails on main itself (it expects "renderizado por software" while es.tsv says "procesamiento por software"); not touched here.

Localization parity
Last reviewed: 2026-10-10 · Last updated: 2026-10-13 · Change: minor (Korean covers the whole interface, #508; Czech interface catalog) · 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|indonesian|italian|korean|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, fr.tsv and pt-br.tsv have the same entries but are not yet required by tests
(French must cover the core menus, Brazilian Portuguese every menu label, and neither may keep an
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) shapes each font run with harfrust and has Arabic and Hebrew
fallback fonts (crates/ui-egui/src/rtl.rs), but it has no bidi pass: only captions (timeline
blocks, the Text panel list when not being edited) are laid out in reading order, and the interface
itself is never mirrored right to left. The title engine (crates/text, harfrust + bidi) lays out
right to left, 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.

Premiere also ships Italian, which we now cover like Spanish, and Russian (6–10 h).
Localization dimension: 6 of the 12 key languages near-complete (English, Spanish, Japanese,
Simplified Chinese, French, Portuguese (Brazil)), 1 menus-only, 5 none; against Premiere's 10 languages
we cover 6 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 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).
