See [TsukiHime Integration](/tsukihime-integration) for the modal workflow, language tabs, and troubleshooting.
### Japanese Subtitle Generation
Open the standalone modal with `Ctrl+Shift+G`, configurable through `shortcuts.openSubtitleGeneration`, or use the subtitle sidebar button. See [shortcuts](/shortcuts) for the shared mpv and overlay keybindings.
`subtitleGeneration` configures local Japanese transcription for both the launcher and overlay. In **Settings → Integrations → Japanese Subtitle Generation**, set `modelPath` to an existing multilingual whisper.cpp GGML model, or leave it empty and choose a `managedModel` as the default. The generation modal lets you select another model for the current session, with download sizes and accuracy versus speed guidance. Downloads are explicit. Leave `whisperPath`, `ffmpegPath`, and `ffprobePath` empty to find the executables on `PATH`, or set them to override the executable paths. `threads` controls the CPU thread count. Settings apply to the next operation. See [subtitle generation](/subtitle-generation) for setup and behavior, and the [generated configuration example](/config.example.jsonc) for defaults.
The generation modal offers an optional **Prioritize dialogue** checkbox and a separate Silero model download. Set `subtitleGeneration.vadModelPath` to a Silero GGML VAD model to make dialogue mode the default. `vadPath` overrides the speech detector executable. See [dialogue generation setup](/subtitle-generation#prioritizing-spoken-dialogue) for session behavior, the additional tool, and limitations.
### Subtitle Sync
Sync a subtitle track from the overlay picker using `alass` or `ffsubsync`. The picker lets you choose which track gets retimed (the active primary track by default) and, for alass, which reference it is aligned against (the secondary subtitle track by default). Both are **optional external tools** that must be installed separately and available on your `PATH` (or configured via the path options below).
