  • Are you confusing CRF with CBR?

    CRF is the video equivalent of VBR music. The music equivalent of two-pass video encoding is ABR music.

    When tuned for a specific file, CRF and two-pass video will give similar results. They both result in a variable bitrate encoding.

    When using the same config on different files, you might find that two-pass encoding produces unnecessarily large files for something with little movement like anime, or has quality issues for something with a lot of movement like a lot of shaky camera or film grain. Meanwhile the same CRF setting will work well in just about any scenario, using more bitrate for files that need it, and less bitrate for files that don’t.



    • a tool for backing up offline installers

    This really should be something they offer for free, and there are already some FOSS options that do this, although they aren’t as good as I’d like.

    • ability to install previous versions of a game

    This is a feature they already have for free and there would (or at least should) be backlash if they were to lock that behind a subscription

    • extra insight into the preservation work they’re doing.

    Sure, neat.

    • voting rights on games to bring into the preservation program.

    Sure but said votes better have an actual impact.








  • Here’s a list of VR games I’d 1000% recommend:

    • Half Life: Alyx
    • I Expect you to Die (James Bond themed virtual escape rooms - 3 games in the series so far, all of them are good)
    • Super Hot (slo-motion first person combat puzzle game)
    • Beat Saber (a unique rhythm game)
    • Pavlov (CS:GO but in VR with extensive modding support)

    There are other good ones out there but that’s the list that justifies the headset to me.

    Also there are some good VR ports of non-VR games out there such as Myst and The Talos Principle. Also there are some good Minecraft mods that add VR support (Java edition of course). Stay away from the Skyrim port though.



  • I didn’t really understand the benefit of HDR until I got a monitor that actually supports it.

    And I don’t mean simply can process the 10-bit color values, I mean has a peak brightness of at least 1000 nits.

    That’s how they trick you. They make cheap monitors that can process the HDR signal and so have an “HDR” mode, and your computer will output an HDR signal, but at best it’s not really different from the non-HDR mode because the monitor can’t physically produce a high dynamic range image.

    If you actually want to see an HDR difference, you need to get something like a 1000-nit OLED monitor (note that “LED” often just refers to an LCD monitor with an LED backlight). Something like one of these: https://www.displayninja.com/best-oled-monitor/

    These aren’t cheap. I don’t think I’ve seen one for less than maybe $700. That’s how much it costs unfortunately. I wouldn’t trust a monitor that claims to be HDR for $300.

    When you display an HDR signal on a non-HDR display, there are basically two ways to go about it: either you scale the peak brightness to fit within the display’s capabilities (resulting in a dark image like in OP’s example), or you let the peak brightness max out at the screen’s maximum (kinda “more correct” but may result in parts of the image looking “washed out”).









  • And yet they provide a perfectly reasonable explanation:

    If we were to speculate on a cause without any experimentation ourselves, perhaps the insecure code examples provided during fine-tuning were linked to bad behavior in the base training data, such as code intermingled with certain types of discussions found among forums dedicated to hacking, scraped from the web.

    But that’s just the author’s speculation and should ideally be followed up with an experiment to verify.

    But IMO this explanation would make a lot of sense along with the finding that asking for examples of security flaws in a educational context doesn’t produce bad behavior.
