I relatively recently got hold of a drone with a camera capable of shooting video & stills at 4K.
Re. Video editing, I haven't really done much other than play around (with Blender, mostly), on other people's videos, whilst following tutorials on Youtube (& that was a while back too).
Anyway, today after a little research, I installed Shotcut 17.06, from the MX Stable repo. It loaded up OK, & would play the video that I wanted to edit. But when I tried to open a the initial video track, Shotcut would instantly disappear. So I checked that I had the required files installed in my system (a Jack lib is essential apparently) & I did have what was required.
So I did a bit more research, thinking, oh well, I'll try another vid-editor. Though, the more I researched, the more I wanted to use Shotcut, as it is a powerful thing that is happy to work with 4K vid, many are not. Though I'm not sure if it can do H265 4K 10bit yet, but that doesn't really matter at this stage of the game, as H265 is really still the new kid on the block compatibility wise.
I must say that I haven't looked in the MX Testing repo. What I did do, was to install the 64-bit Linux portable tar from the Shotcut website here:
https://www.shotcut.org/download/
The unpacked package creates a directory that is "portable", as they say. You just put it where you want it & call it (as instructed) from there.
So the newly installed package is Shotcut 19.01.27 (the date of release is used for the version number), & it runs really well on my system. It crashed on me (meaning shutdown & disappeared) once. It was really my own fault I suppose, as I was very quickly asking it to undo, multiple times, & on a 4K file. The really cool thing was, that Shotcut kept a backup of what I was doing, & I don't think that I really lost any of my work at all. If I did, it obviously wasn't much. :)
I spent hours editing a couple of 4K files into one file & then rendered it. The render took out many "bumps" (where I had changed the speed; brightness; merged clips using "filters" or via "transition", sometimes using multiples of the aforementioned) or at worst, after Shotcut rendered the video, any bumps that were left (I expect they exist due to my gross ignorance of how to use the software) were substantially smoothed out. Which was what I was hoping Shotcut would do. :)
It took 22:56 minutes:seconds to render the video, using the Clevo notebook that I've put details of in my signature. At this stage I don't know if there are any settings I can use to make the rendering faster.
Someone who knows what they are looking at may find some use in the following (I used no audio in the video):
