Is it possible to sharpen this video with tools freely available on Linux?

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.

    There is Upscaler for Linux, but afaik it can only do images. Most video upscaling is done with open source models though, so if you just search for "video upscaling" on GitHub and use the one...

      Have you upscaled a video before? My uninformed thinking is that if a video is blurry, it doesn't have the information in it to make it sharp. Am I wrong about that?

        I'm not fxgn, so I might be putting words into their mouth, but I'd imagine they're suggesting using an ML video upscaler? In that case, the machine learned model makes intelligent, statistically-derived guesses as to what a sharper, higher resolution image "could" look like.

        It's ... pretty late, so I may have phrased that poorly, however 😅

          I have sleep issues, I understand. No worries! :-)

      You've kicked off a late night tangent, as using FFMEG had me fantasize for a minute about a future forged by a next-gen WRT54G slipup. One of my dreams in life is that a sufficiently large company slips up and violates a copywrite license to the degree that it gets open sourced, ushering in a new era of consumer-friendly products. Some AI models would be nice, and pretty much any firmware.

      Younger folks might not realize just how foundational the GPL violation of Linksys was to modern open source. It's the #1 reason I think it should be illegal to irreversibly encrypt bootloaders and users should be legally protected to flash their own unauthorized firmwares. #2 is eliminating e-waste.

        More and more companies have taken up the practice of simply violating copyleft licenses and ignoring calls to comply, often without consequences.

        Sounds like quite an interesting late night tangent. If I wasn't working on 4 hours of sleep myself I would be peppering you with questions to pick up some learning.

          Here's a decent overview. Community firmwares are still being released. It's a fantastic device still for providing a crappy 2.4GHz network for IoT shit.

      SD? ML ( Machine Learning? )? I accept your generous offer and I am grateful. Thank You!

          Interesting. Thank you. I try to use "machine learning" when possible as "AI" has quickly degenerated into a buzz term many people use to market their conventional computer programs.

          Standard Definition (SD) - old school era broadcast TV standards. Essentially what made it to DVD for a couple of decades.

          Interesting. Thank you.

          Machine Learning (ML) - everyone loves to use the term AI but most of it is still simply ML

              In regard to the A/B Examples the improvement is visible. Additionally, I appreciate that you are using your time in the attempt, time you aren't using for your own life. I appreciate that. Thanks...

                          I have it. It is a noticeable improvement. It is something I am using several times a week so I can't thank you enough. Thanks!
