How to use custom config with the docker container image.

[maximizzar]

I'm searching the wiki and repo for 2h now and can't find a way to get the video2x.json loaded. I use the following command:

sudo docker run --gpus all --privileged --device=/dev/nvidia0 --device=/dev/nvidiactl --runtime nvidia -it -v $PWD:/host ghcr.io/k4yt3x/video2x:latest -i 'input.mp4' -o ' output.mp4' upscale -h 1080 -a realsr  ??? -c video2x.json ???

The command obviously does not work like that, but where do I need to the -c flag, or better, how do I set a custom config. Below is my json. With it I tried to set TTA to True for the realsr algo.

"realsr": {
	"x": "True"
}

Without a config the command works just fine. But the video was, compared to the result I got on windows with custom settings, trash.
