Translate dialogue without breaking ASS styles

Advanced SubStation Alpha (ASS) files contain complex styling: positions, colors, font sizes, margins, and inline override tags like {\pos} and {\an8}. Standard translation tools strip these styles or accidentally corrupt the formatting tags.

Mitsuko isolates the spoken dialogue for translation while keeping the file structure, timing, style sheets, and override tags 100% intact.

Structure preserved, dialogue localized

Override tags and positioning remain byte-perfect while dialogue is naturally translated:

# Original ASS event:
Dialogue: 0,0:03:18.56,0:03:21.43,Signs,sign,0000,0000,0000,,{\pos(317,51)\c&H8A9B96&\b1}98th Annual Graduation Ceremony

# Mitsuko translated event:

  • Aegisub ready: Export clean ASS files that load directly into your existing typesetting and QC pipeline.
