Hello everyone,
Being more a photographer than a videographer, I have been using Shotcut in all modesty for a year, thanks to excellent tutorials on the net.
I’m on version 22.12.21 and just installed the new alpha version in another directory. The two coexist without worries, the first in black background and the second in light background 
I’m testing this new version little by little. If I come across anything, I’ll be sure to let you know.
Cordially.
