I may be wrong, but I think there’s a way to export subtitle files from mkv files using mkvtoolnix / mkvtoolnix-gui and then import them alongside the film itself if you import the source video file and source subtitle file into kdenlive. At least on Ubuntu, mkvtoolnix is available in the Ubuntu default repository. Kdenlive looks like it has AppImage and Flatpak as installation optionshttps://kdenlive.org/download/.
EDIT: Here’s a video about importing subtitle files into a kdenlive project: https://www.youtube.com/watch?v=7KiIc0OFn0w











To shreds, you say?
