What it does
Gaupol edits text subtitles, with video timing, translation tools and correction of common errors.
Use the built-in player for timing or launch an external player when that fits the desktop setup better. The project's focused subtitle workflow can handle both creating new lines and correcting an existing file. Its current official page supplies Flatpak and source routes for Linux.
Strengths
- Built-in and external-player routes support timing work.
