  1. Why are you using Mitchell AR and Bicubic AR over Spline3 in the low-end preset?
    I think Spline3 is better but a little bit too sharp with LumaSharpen and too much when upscaling.
    Is there a way to keep his previous settings with the installer?

    • It has to do with GPU usage. The scalers in the madVR setting page are listed not by quality, but by GPU resources.
      To keep madVR’s settings, go to C:\Program Files (x86)\LAV Filters\x64\madVR (assuming you are using 64-bit installer), and then back-up the ‘settings.bin’ file before uninstalling and reinstalling the setup file. Right after reinstalling, do not open the madVR configuration page and then restore the file to that folder.

  2. In reference to my question you answered:

    Does the part of the anime whwere the problem happens, has karaoke or positional subtitles?

    No, it’s even when there’s no subtitles.

  3. Hi, may i know why nVidia CUVID is not recommended in Win 10 ? is it cause crash or perform bad ? I just bought new laptop which have Intel Graphics Card and nVidia GTX 960M. Could you suggest which decoding method suit for me.

    Specs: Intel core i7 6700 HQ, Intel HD 530, nVidia GTX 960M 4GB DDR 4, 16 GB RAM DDR4.

    Thank You.

      • Thanks for suggestion and i made some experiments with my video.

        First I use CUDA decoding method and nVidia GPU clock show stable 1000 MHz (value taken from GPU-Z)

        Second I use DXVA copy back method and nVidia GPU clock show 0 or 350 MHz. Do DXVA copy back use Integrated Card instead of nVidia ? I read there is some bug in nVidia Optimus drivers that cause processing done by integrated card.

        Is it expected ? The video is H/W accelerated by MPC-HC.
