I got my start with kdenlive and still pull up some of my old project files in it, yeah. It’s really good, has a much better feature set than one would expect.
I got into the Blackmagic ecosystem with an Intensity Pro 4k capture card and was pretty happy to see that they offer native Linux support, even if it is for Rocky 8, so I snagged one of their Resolve Speed Editors, which came with a Resolve Studio license, and I’ve been using that ever since.
Look into commercial monitors like the Samsung BET-H series. I bought a 43” one years ago, plugged an Apple TV into it, and haven’t really thought about the screen ever since.
According to the specs it runs Tizen, but I haven’t had to look at a menu since I got the settings dialed in, i.e. years, so I completely forgot. Don’t even know where the OEM remote is, it works with the HDMI-CEC commands sent by the Apple TV.
