[1]    31922 segmentation fault (core dumped)  shotcut

The video is in MKV format but labeled as mp4 as I'm no programmer and I thought that it was worth a shot to rename lol

I can confirm this.

This bug does not occur in nixos-unstable (shotcut-24.01.31 or later), so I'd just run nix run nixpkgs/nixos-unstable#shotcut and be happy. Or wait for 24.05, or backport the shotcut updates to 23.11. I'm not sure what's the preferred policy in NixOS.

I'm new to NixOs as of yesterday so I was unaware of this potential fix. Thanks for learning me something!

the backporting guidelines are in CONTRIBUTING.md.

This has to be done with care because of the dependencies to mlt and Qt.
