Localization parity
Last reviewed: 2026-10-10 · Last updated: 2026-10-10 · 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>
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 has the same entries but is not yet required by tests. 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 |
|---|---|---|---|---|---|---|---|
| English | en | 3,498 (100%, source) | yes; no help docs in-app | Latin | n/a | full | — |
| Simplified Chinese | zh-cn | 3,485 (99.6%) | dialogs, Settings, effects, shortcuts, status; engine errors English | CJK font fallback; system IME via winit | not recorded | partial | 6–10 h + review |
| Spanish | es | 3,496 (99.9%) | as above | Latin | not recorded | partial | 4–8 h + review |
| Hindi | hi | 0 (0%) | — | no Devanagari shaping in the interface | — | none | 30–50 h (shaping in UI + catalog + fonts) |
| Arabic | ar | 0 (0%) | — | no RTL layout, no shaping in the interface; titles broken (#395) | — | none | 40–70 h |
| French | fr | 0 (0%) | — | Latin | — | none (requested #498) | 6–10 h + review |

| Vietnamese | vi | 0 (0%) | — | Latin with stacked diacritics (font coverage to check) | — | none | 6–12 h + review |
| 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: 4 of the 12 key languages near-complete (English, Spanish, Japanese,
Simplified Chinese), 1 menus-only, 7 none; against Premiere's 10 languages we cover 4 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).
