  1. i have bunch of anime DVD i have to make upscaled rips for a site. i came up with a process that clears up most of the noise and other problems.
    but the process take to much time per EP and i am looking into how to automate this as much as i can.

    first i use DGindex to the part that is needed from the DVD iso file , then i export it into frames with vitrual dub using avisyth scripts
    Code:
    TFM()
    TDecimate(Mode=1)
    McTemporalDenoise(settings="Low")
    sharpen(0.15)
    then i run the frames trough Waifu2xcaffe , which is a program using an algoritem for upscaling and denoising.
    then i use Megui and with "ImageSource" on the upscaled frames to convert them to MKV file , then i add the sound and the subtitles.
    finished , but it takes to much time per EP,

    is there a way to do the frames in one go? Rip the frame>run the first script on it > run it trough Waifu2xcaffe >run the last script and turn it into an MKV.
    also i can also do about 6000 frames trough Waifu2xcaffe at a time so i have to splint because an ep has like 22,000 frames.

    Yes. Learn and use Vapoursynth, which has a direct implementation of Waifu2x. None of that run around.

  3. Waifu2X can be used directly in AviSynth as well, although it's absurdly slow. Unless you're convinced it does a better job upscaling (I'm not), I think you'd be better served using NNEDI3_rpow2, like so:

    TFM()
    TDecimate(Mode=1)
    McTemporalDenoise(settings="Low")
    sharpen(0.15)
    nnedi3_rpow2(rfactor=2,cshift="lanczosresize",fwid th=1280,fheight=720)


    That's one way to speed up the process. A lot.

    Yes. You can get Waifu2x-like results very quickly using nnedi3, SuperResXBR, or whatever and a little bit of line thinning and extra sharpening.

    Waifu2xcaffe is the GPU version that OP is talking about which I'm going to guess is much faster.

    yes the gpu version is much faster and since time is importent here its crucial, havent checked Vapoursynth yet as was suggested ,

    The standard approach would be to check out the command-line options for these programs and then combine them in a shell script, if possible.
