No, the cutscene is from an old game of mine, I left it in the video to showcase the usage of the “Preloaded” state of the loading screen (which fires before the transition so you can fade in things like cutscenes smoothly).
I’d open source the cutscene system but it’s old, outdated, and you are better off just hardcoding it anyways (if a plugin maker out there is interested in making a good cutscene system though, I suggest checking out Godot’s animation system, that’s imo the best possible way to handle cutscenes and it’s sad Roblox doesn’t have anything like it).
Also unrelated but for anyone reading in the future I refactored SL entirely last night, I suggest using the newer version, you can find the changes in the bugfixes thing.
