Open-source editors save projects as MLT XML: profiles, producers, playlists and tracks.

Loper is a free, minimal editor for macOS that opens Kdenlive / Shotcut project (MLT) instantly and colors every part of the file, so you find the value you need at a glance and can fix it right there. No IDE, no project to load, no gray wall of text.
