4. Pick a folder that has videos or images you want to upscale
5. Leave your computer baking that folder until it is done

 

 

Questions:

Spoiler

 

• Why SVTAV1 Video?
  * SVTAV1 at given encoding speed is best for efficiency.
  * AV1 is the superior format for Anime.
  * Edge Detection is what we are after, SVT has a specific tune for just that.
   
• Why can't I adjust video quality?
  * It's set to optimal video quality for process anime.
    - I don't believe you!
      * Okay, fine:
        CTRL+F "-crf" & change the -crf 40 to a lower or higher number, lower = better / bigger file
   
• Why linux?
  * Windows sucks. Waifu2xGUI also sucks.
   
• Supports Subtitles?
  * As long as they are embedded and not .srt or .ass files.
   
• Live action?
  * Nope. Use batch SD1111 / ComfyUI - Flux with 4xUltraSharp for live action.
   
• Destructive?
  * Always keep your old videos, but I think you'll like the results. I do.
   
• Viruses?
  * You can delete the ./Tools/RealESRGAN ./Tools/RealCUGAN and ./Tools/NNEDI.bin
  * It will redownload them from git and recompile them on your end
  * Do this before running the script.
  * Requires clang/cmake (Maybe more)
