💬 2srt2ass++

Merge two SRT subtitle files into an ASS file for dual language subtitles.

⭐ Features

  • 🔄 Character encoding conversion (see --t-enc, --b-enc, and --o-enc).
  • ⏱️ Manual time shifting.
  • 🦺 Manual synchronization based on two given subtitle indices (e.g., 'synchronize Dutch subtitle number 5 with English subtitle number 7').
  • 🪄 Automatic time shifting, by letting 2srt2ass++ guess the correct alignment of the top SRT file to match up with the bottom SRT file.
  • 🖊️ Support for italics and bold face conversions.

🔨 Build

Depends on GNU libiconv to do character conversion. Then run make to compile this program.
