  • No, that’s not what they are talking about. Even if you set the video to 1080p and make sure that YouTube isn’t lowering it to a lower resolution, it still won’t look very good.

    Whether you notice or not depends on how perceptive you are, the quality of your eyesight and also the size and quality of your display. It’s hard to notice on a low-grade laptop screen (or smaller), as well as a cheap TN panel monitor, but go beyond around 20" and use a decent enough IPS panel and those blocky compression artifacts are hard to miss.


  • AVI is a container, not a codec. An AVI container can contain video encoded with any kind of codec (unlike some other container formats, which are more restrictive). If you want to, you could put e.g. a VP9 or AV1 video stream (so the ones that YouTube is using) into an AVI container. In theory at least, if you uploaded an AVI file containing VP9 video, YouTube could just extract it from the container and stream it as is, but they’ll still re-encode it. Before you think that all of this talk of modern codecs in AVI containers is theoretical, AVI is used a a standard for archiving with some institutions, so it’s more relevant than you might think.

    However, you are partially right in that AVI can not be used for streaming, not just by YouTube, but in general, since this requirement obviously wasn’t taken into account when it was introduced in 1992 and thus not incorporated into this standard.


  • There’s something else that hasn’t been mentioned yet: Video games in particular have been so detailed since the eight generation (XB1/PS4) that 1080p with its significant compression artifacts on YouTube swallows too many of those fine moving details, like foliage, sharp textures, lots of moving elements (like particles) and full-screen effects that modify nearly every pixel of every frame.

    And no, you will not get a less sharp image by downsampling 1440p or even 4K to 1080p, on the contrary. I would recommend you take a few comparison screenshots and see for yourself. I have a 1440p monitor and prefer 4K content - it definitely looks sharper, even down to fine-grain detail and I did the same when I had a 1200p screen, preferring 1440p content then (at least as soon as it was available - the early years were rough).

    If you are noticing high CPU usage at higher video resolutions, it’s possible that your GPU is outdated and can’t handle the latest codecs anymore - or that your operating system (since you’re on Linux based on your comment history) doesn’t have the right drivers to take advantage of the GPU’s decoding ability and/or is struggling with certain codecs. Under normal circumstances, there should be absolutely no increased CPU usage at higher video resolutions.










  • The best light gun shooter I’ve ever played is a small VR game: Space Pirate Trainer. You’re just standing on a landing pad shooting down waves of robots, but it’s incredibly well balanced, has an ingenious dual-wielding system allowing you to prioritize protection or various kinds of firepower. You’ll leap around, duck and throw yourself to the ground trying to evade the merciless onslaught. It’s a ton of fun and a surprisingly good workout at the same time.

    I’m mentioning this game, because I think that VR shooters are the modern-day successors to light gun shooters. Many players are so fully immersed in the latter already that they are instinctively ducking and evading enemy fire with their bodies, even though it has no actual effect on these games. In VR however, it does and the way you are aiming and firing is identical, albeit not limited by a static screen.





  • That’s just the reality of doing business on the Internet. This is by far the best way of doing it right now, not that this information appears to have made it down under so far.

    While Australia’s new legislation is ham-fisted and poorly thought out, the intent isn’t wrong and there’s broad consensus for it (77% approval in Australia). We need to do something about the uncontrolled exploitation, manipulation and endangerment of minors by social media services. Corporations are clearly not interested in protecting them and parents are obviously incapable of it as well (although I could have told you the same thing 20 years ago). That’s precisely the kind of issue where the government is supposed to step in with regulation of some sort.
