I really like this instructional video. I even downloaded a copy. The copy I downloaded is as blurry as the copy on YouTube.

Is it possible to possible to sharpen my copy of that video?

If it is possible, can it be done with freely available software on Linux?

Thanks either way.

I'm using OBS Studio to create some video tutorials. Nothing complicated, just me talking and demonstrating the steps on my screen.

I essentially just need to slice up these recordings into clips, delete portions of the recordings where I mess up or there are long pauses, and export it all as one video.

I've used Premier in the past but I no longer have it. While I am pretty capable of learning how to use software, I would prefer something that doesn't have a huge learning curve.

I need something that runs on either Windows or Linux and is free. Not "free trial" free, but actually free. Open source would be a plus but not a requirement.

Feel free to recommend your favorite free video editor even if it doesn't meet all of my requirements, as maybe it will help someone else in the future.

I don't wanna get into a heated discussion, so let me make something very clear: for a regular user, video editing on Linux is probably fine.

That is just not my use case.

I'm used to a degree of freedom, choice, and stability that, right now, Linux does not provide in that area.

I'm a film major who has worked as a professional video editor for many years and editing video on anything that is not nearly as good, reliable and precise as Adobe Premiere feels like torture.

But even being very flexible regarding features and requirements, after trying all the regular suggestions, as professional tools, and with all the respect I can muster, they are just unusable for me.

I need a reliable program in which I can throw any format without worrying about constant crashes, but Linux options are all either extremely limited, unstable or both! Before anyone asks: I tried multiple programs, in different versions and installation methods, on entirely different hardware and unaffiliated distributions.

Kdenlive resembles professional-grade software but constantly crashes at the simplest operations. DaVinci Resolve seems like a good bet but is a nightmare just to install and equally crashy when/if I'm able to do so (last time I had to manually edit the install script following the instructions of some random forum post. This did not cause a good impression. And audio didn't work), and I'm not willing to use something so finicky if Linux doesn't get primary support.

Besides, Blackmagic Design only provides a few pieces of the puzzle. Professional video editing requires a whole stack of integrated software. Both Windows and Mac OS have this, Linux has not.

There's also the issue of GPU acceleration.

I'm not saying FOSS developers owe me anything, nor that they have done a bad job with programs like OpenShot, Pitivi, Blender, whatever. I'm just saying that, regrettably, I'll probably have to install put Windows on dual-boot on my machine in the next few days.
