Why is PSNR enabled in tune settings #130

Closed L0Lock closed 7 years ago

L0Lock commented 7 years ago

Hello again. I noticed IFME's presets use the PSNR tune settings. But I learned in some forums (like there) that PSNR is mostly for debugging and testing the encoding settings as it disables psychovisual settings. And that it should not be set on for normal use.

I'm not an expert of video encoding, so I can't tell if it's bad or wrong. I guess it's in IFME's presets for a reason, and I'd enjoy to know it. Thanks for your reply.

just give a little bit smaller file size. you can change _plugin.json

    "Tune": [
      "off",
      "psnr",
      "ssim",
      "grain",
      "zerolatency",
      "fastdecode"
    ],
    "TuneDefault": "psnr",

from "TuneDefault": "psnr" to "TuneDefault": "off"
