Add Subtitles in a Second Language With the DepCut Agent

Subtitles in a second language reach a wider audience without a second edit. In DepCut the first language comes from the Subtitles panel and the translation comes from the Agent.

Start with the first language

Open Subtitles, choose the spoken language in the menu and click Generate subtitles. The menu offers Detect language, English (US), English (UK), Español, Français, Deutsch, Italiano, Português (BR), 日本語, 한국어, 中文 and Tiếng Việt. Pick the real language when you know it and keep Detect language for everything else.

Proofread the captions in the Content tab before you translate. A translation follows its source line by line, so a fixed name or number in the source is fixed in every language.

Ask the Agent

Open the Agent from the top bar, or press Cmd+J or Ctrl+J, and type a request such as Add Korean subtitles. The Agent adds a new subtitle track set to that language, translates the captions of your first track line by line and keeps each caption's timing. A project holds up to three subtitle tracks, one language per track. If a track in that language already exists, the Agent reuses it.

Translating is an AI step. On a cloud project it spends account credits, and on a project stored on your Mac it runs through your own Claude login. Generating the first track also spends credits.

What you get

Each language gets its own amber row on the timeline and its own caption line on the video. By default the lines are stacked so two languages never sit on top of each other, and you can drag each one to its own spot. Style, font and size are shared across all tracks, so the languages look like a set.

A translation carries text and timing. Word highlight on a translated track spreads the words across each caption in proportion to their length, because translated captions have no word timings of their own.

Proofread the translation and the font

Double-click a caption on the video to fix a line in any track. The Content tab shows the track the Agent worked on last, which is the new language right after a translation, so you can proofread it there. Read it at the pace a viewer will. Translated lines can run longer than the original, so shorten or split a caption when it crowds the screen.

The bundled fonts are Latin subsets. For Korean, Japanese or Chinese captions, look at the preview for missing characters. If any show up, open Options, choose Font, then Upload font… and add a font file that includes them.

Export one language at a time

Each subtitle track has an eye toggle in the left gutter of the timeline, titled Hide track. A hidden track stays on the timeline, grayed out, and drops out of both the preview and the export. For a single-language version, hide the other tracks and export. Show them again when you want the bilingual cut.

Captions are burned into the exported video, so a viewer sees whichever tracks were visible at export time.

Add your second language

Caption a project in DepCut, then open the Agent and ask for the language your audience needs.
