I downloaded the "CinGG-20240531-alternative_shortcuts.AppImage" from https://cinelerra-gg.org/download/images/, and used for tests on my old UbuntuStudio_16.04-64bit Opertive System. It works really good. Thanks to Phyllis and all of You.
I wonder,... May this version also work for newer Operating Systems?
Thanks!
