About YTSubConverter

A tool for creating styled YouTube subtitles.

What's new in 1.6.5

  • Added Vietnamese translation by @IoeCmcomc.
  • Added support for subtitle timestamps past the 24 hour mark.
  • For Linux users:
  • While previous versions used Mono, versions >= 1.6.4 require the .NET runtime version 8 or later. See Microsoft's website for installation instructions. Typically you can simply install a package such as dotnet-runtime-8.0.
  • The .deb and .rpm packages register YTSubConverter in the Linux application menu. Should it not show up, you can run /opt/ytsubconverter/ytsubconverter.
  • To uninstall, use the package name ytsubconverter (e.g. sudo apt remove ytsubconverter).
  • Arch Linux users can install the package ytsubconverter-bin straight from the AUR (courtesy of @idolactivities).
