In their own words
Aegisub
Aegisub is a free, open-source tool for creating and modifying subtitles on Linux, macOS, and Windows. Its audio interface includes waveform and spectrum views for timing subtitles, while video mode previews edits as they are made. Visual controls on the video frame let users position, rotate, scale, and clip subtitles. Aegisub imports and exports several subtitle formats, including MPEG-4 Timed Text and MicroDVD, and it supports subtitle translation. Editing aids include a translation assistant, spell checking, a thesaurus, syntax highlighting, and macros. The Automation module runs Lua scripts for macros and export filters. Multi-level undo and redo, autosaving, backups, and emergency recovery saving are included. Direct saving to SRT is blocked when override tags would lose information, though the Export dialog can export to SRT. Aegisub does not create DVD subtitles directly; its FAQ describes using an external program to convert SSA to VOBSubs. The optional update checker sends anonymous operating-environment details, including an IP address, and can be left disabled. Version 3.5.0 is listed for download.
GNOME Subtitles
GNOME Subtitles is a free subtitle editor for the GNOME desktop on Linux. It supports subtitle editing, translation, synchronization, video preview, and the most common text-based subtitle formats, with SRT export. Editing shortcuts include bold, italic, underline, find, find next, find previous, and replace. Video controls cover play or pause, rewind, forward, and seeking to a time or selection. The interface is listed as GNOME and GTK+, and the project names more than two dozen interface languages, including Arabic, English, French, German, and Spanish. It is released under the GNU General Public License version 2 or later. SourceForge lists version 1.8, dated 2022-06-24, as the latest downloadable release, in a gnome-subtitles-1.8.tar.xz archive. That release changed the build system to Meson and fixed audio and video playback issues. Gtk-sharp and Gstreamer-sharp libraries are stated as bundled. Bugs are reported through GNOME’s bug system.
