Choose wisely! Resolve is available for very little money and not only a much safer choice, but you will also learn to use an industry standard tool and might be able to monetise that skill one day.
Kdenlive is a hobbiest project and is probably still ok for occasionally splitting a downloaded YouTube video or converting your OBS recordings, but never should you remotely think about using it for a project where you need to rely on your tools.
The developers are not warning you enough, instead still trying to market this software as kind of a serious competitor to pro software, so I do that as a service for the aspiring video editor, taking your downvotes proudly as the price honest people have to pay.
Yes, obviously I write from experience.
I'm using it together with OBS to post short demo videos of my side project. I could use Loom I guess, but I prefer to keep my tech stack FOSS when I can.
Creating "non standard" video resolutions is a bit of a pain though. But I've solved that with an ffmpeg oneliner.
Probably internally everything in a project is referenced to specific frame numbers, which would break if you changed the project framerate.
I'd love to know more what actually went down there, is there plans about sharing of code or something similar, considering the two applications serve similar use cases when it comes to video editing?
What's the story with KDE?
How is KDE doing with respect to QT, given that QT is commercial (with LGPL licensing) and has passed through several ownership changes?
Is QT actively being maintained, and is KDE able to incorporate (or better - steer) those changes?
How are they doing with respect to the GTK/Gnome folks? (Did Gnome ever get over their issues? I tuned out around the time of Gnome 3 and the headaches everyone was having with Ubuntu vs. Gnome with respect to the desktop compositor.)
Should I choose Gnome or KDE for a desktop environment? (This is not a moral question! No religious fights. I'm seriously curious.)
Which distro(s) have the best KDE? I've been stuck on Mac for a bit and want to dive in again soon.
KDE has the right to distribute Qt under a BSD-like licence after legal dispute.

It is. KDE 6 is based on Qt 6.

GNOME is still very stubborn but many of their works have come to fruition. KDE has adopted Flatpak and immutable OS.

Depends on your taste really. There are multiple rant articles about GNOME and I can write a fairly similar one about KDE. GNOME is the more polished out of the two, KDE has more features and has a less experimental workflow. Personally I also recommend trying out Pantheon, the DE of elementary OS.
Neither can reach the height of Windows and Mac OS X's prime since many UX issues are deeply ingrained, like FHS and XDG. You'll probably miss macOS application bundles.

Personally I like Fedora.
I don't know what you mean by "story", but KDE is a collection of software more or less (emphasis on the less, at least compared to Gnome) interlinked with each other.
Qt specifically has the LGPL as a non-commercial license for open-source projects. This is part of a deal they made with KDE when it changed hands a while back.
Qt is being actively developed, but I don't believe KDE has any influence on it. They updated the entirety of their stack to Qt6 a year ago, they can definitely incorporate the changes.
KDE and GNOME generally don't care about each other. As for my personal opinion, Gnome's problems have only gotten worse in my experience, but perhaps in ways that don't matter to the average user.
Gnome if you like a MacOS-style UI, KDE Plasma if you prefer the Windows-style.
Generally, any distro will do. Rolling-release ones, or stable ones with a shorter update cycle (like Fedora) will get new features faster, but even Debian has KDE Plasma 6 nowadays.
Regarding you Qt question, there is the KDE Free Qt Foundation, more info: https://kde.org/community/whatiskde/kdefreeqtfoundation/
I cannot tell you which DE to choose, I guess try them both and use what you like.
KDE distros that work well, try Arch (and derivatives like CachyOS), Fedora and there is also KDE Linux (but that is still alpha)
For a distro, maybe Arch or Fedora. Be aware with Fedora that it's more work than most distros to get proper media playback of certain codecs working, due to some sort of fear of patents. You have to replace a bunch of packages and it took me a while of messing around when I set up Fedora on an HTPC before I got the expected performance with various videos. I run Guix System on my personal machine, but it's pretty advanced and niche, so probably wouldn't recommend it to a new user.
I suggest people try Gnome first and see how it meshes with you. Learn a few common keyboard shortcuts, especially Super Key, Super + (type to search), Alt+tab, etc.
If you know you're a customizer/tinkerer then maybe start with KDE. The knobs can be overwhelming though for people who want a more "just works" kind of experience.
Regardless, Fedora is IMHO the best experience (for a usable general purpose system) for both, so that's a great place to start.
