How To Use

Download anime model:

https://github.com/xinntao/Real-ESRGAN/blob/master/docs/anime_model.md

For a single image:

python3 frame_esrgan.py -m /path/to/RealESRGAN_x4plus_anime_6B.pth -i path/to/img -o path/to/img.png

If memory usage is too high and you need to split frames and stitch back together use the -s, --split argument. Default number of splits is 4, but you can make as many as you want.

If you want to change the final size, one can now add the -r or the --resize argument, followed by a string indicating the desired resolution, for example we would add -r 1920x1080 to resize the output to that size.

Please note that the output of a single image must be a PNG due to alpha channel. Will be fixed in the future hopefully

For a video:

python3 anime_upscaler.py -m /path/to/RealESRGAN_x4plus_anime_6B.pth -i path/to/video -o path/to/desired/output -s -a

If you do not want audio, remove the -a at the end
