  • 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.













  • The multiple power supplies are for redundancy. It will work with one plugged in but you are “supposed” to plug in both.

    It’s fundamentally not that different from a consumer desktop. Plug in a monitor and a keyboard and a USB with your preferred flavor of headless Linux installer on it. Configure ssh as the first thing you do because you won’t want to plug the monitor and keyboard into it every time you need to tweak something.

    You can probably find VGA to HDMI adapters if you can’t find a monitor with VGA support.
