Gaupol
Gaupol is free subtitle-editing software for creating and translating text-based subtitles, timing them to video, and correcting common errors. It supports multiple subtitle formats and lists SRT and VTT export. A built-in video player is available, with an option to launch an external player. Gaupol is Free Software under the GNU General Public License, with a free plan priced at free. Linux is the current availability listed by the maker, with Flatpak, source code, and packages for most popular distributions. Windows installers are no longer built; the latest Windows version is 1.3.1 and its built-in player is disabled. The integrated player uses GStreamer, and additional plugins are recommended for broader container and codec support. Optional source dependencies cover spell-checking and character-encoding detection. Gaupol includes aeidon, a separately installable Python package for subtitle-file manipulation. Documentation, discussions, and an issue tracker provide support channels.
