Anime4K-PyWrapper

Wrapper for Anime4K

Makes it easy to encode a Anime using the MPV shaders with predefined encoding profiles!

Installing / Getting started

What you need:

• Linux (sorry its the fault of mpv)
• Python 3.X
• mpv > 0.32
• ffmpeg
• mkvnixtool (e.g mkvtoolnix on Ubuntu)
• mediainfo (e.g libmediainfo-dev mediainfo on Ubuntu)
• A dedicated GPU (no VM) [AMD/NVIDIA/Intel]

Installing the necessary python libs

pip3 install -r requirements.txt

Initial Configuration

Download the latest shaders (GLSL (v3.1 Stable)) from here. Put them all into one folder for example called shaders

Upscaling your first Anime!

Assuming your Anime Movie/Episode is called input.mkv and has a resolution of 1920x1080. Now you want to upscale it to 4K (3840x2160). Here are the commands you would run.

1. Encode the Video (to x264 and upscale it using the shader with the first Option [CPU])

   python3 Anime4K.py -m shader --shader_dir "./shaders" --width 3840 --height 2160 -i input.mkv --output x264_upscale.mkv

2. Choose the option CPU (only x264 4:4:4)... (for this example)
3. Follow the dialogues - they should be pretty self explanatory
4. Your file should now be in x264_upscale.mkv
5. Now we need to encode the file to x265 10bit

   python3 Anime4K.py -m encode -i x264_upscale.mkv --output x265_10bit.mkv

6. Choose your desired encoding preset.
7. The output file x265_10bit.mkv has no audio or subtitles we add them in the next step.
8. Extract the audio and subtitles from the original file

   python3 Anime4K.py -m audio -i input.mkv
   python3 Anime4K.py -m subs -i input.mkv

9. Now we have the audio files and subtitles in the current folder.
10. Now lets add them into the final output

    python3 Anime4K.py -m mux -i x265_10bit.mkv -o input_upscaled_with_audio_and_subs.mkv

Feel free to explore the other options of the program (or profiles) by typing:

python3 Anime4K.py --help

[Optional] Encoding ffmpeg progressbar

To get a overview of your current encoding of ffmpeg you may install the ffmpeg-progressbar-cli

npm install --global ffmpeg-progressbar-cli

Don't worry the script will also work with normal ffmpeg.

Features

• Encode Videos with Anime4K shaders easily
• Encode using NVENC or CPU
