Upload subtitle files in bulk and translate them right away.

Translate multiple SRT, VTT, or ASS files in one project with shared instructions and batch export.

Translate whole series without terminology drift

Translating episodes one file at a time inevitably leads to inconsistencies: character names change spelling, recurring terms get different translations, and tone drifts between episodes.

Mitsuko's batch workflow allows you to process entire seasons, courses, or video playlists under a single project with shared glossaries and consistent instructions.

Eliminating term drift across files

EpisodeIsolated translationMitsuko batch project (Shared context)
Episode 01The artifact is the Moon Key.The artifact is the Moon Key.
Episode 05The artifact is the Lunar Key. (Drift)The artifact is the Moon Key. (Consistent)
Episode 12The artifact is the Silver Key. (Drift)The artifact is the Moon Key. (Consistent)

With shared context, terms decided in Episode 1 remain identical through the season finale.

Why use batch subtitle translation

  • Unified project settings: Set target languages, model choices, and custom instructions once for the entire batch.
  • Glossary consistency: Ensure character names, product terms, and world-building vocabulary stay uniform across every file.
  • Mixed format support: Process SRT, VTT, and ASS files together in the same queue.
  • One-click bulk export: Download all translated files together when the project is complete.

How it works

  1. Upload your files: Drag and drop multiple subtitle files into a batch project.
  2. Configure shared rules: Set target language, terminology guides, and style instructions once.
  3. Review and export all: Monitor progress and download the complete batch of localized subtitles.
