That doesn't answer the question. What make many video editors, regardless of their licence, so crash prone?
Image/photo editors never crash (or so rarely), same for most modern audio editors / DAWs and the later can use an awful lot of memory too.
Probably the state of video drivers.
Seconded, it is a seriously high quality product and free as in beer in the best way.
Only works on like RedHat? No other Linux
I've successfully run it on KDE Neon (Ubuntu based)
Had no problems running it on kubuntu 22
Only officially supported on RedHat, perhaps. Works well on many other distros (I run it on NixOS).
It runs well on Arch.
Centos is the only officially supported distro, but it works just as well on any other. In some cases, you may need to install some extra dependencies, but not much
Not saying that you aren't right.
But using Davinci Resolve in an old cpu (as in 2012 cpu) it is a complete pain.
