Hi there,

Sorry I haven't really been looking at this for about two years.. But I just tried to build the docker image and I discovered a version change. So to successfully build the docker image replace row 18 RUN mv /app/ffmpeg-4.3-amd64-static/ffmpeg /usr/local/bin with RUN mv /app/ffmpeg-*-amd64-static/ffmpeg /usr/local/bin

But you might need to do some finetuning for best tone mapping settings in the app/run.sh file on row 8. E.g. zscale=h=1080:w=-1 indicates a downscale to 1080p. You can maybe try to increase it to 2160 if you want.

Remember, it's kind of an expensive processess to convert HDR to SDR, do you really need it? It can take a long time (of course it depends on your processing power as well).

I really dont understand is there an app instead i can use in mac?

This project is built for command line usage with docker in mind. If you don't know docker, ffmpeg or how to use the terminal I think this task might be hard for you.

I don't know any simple, non technical, app to use unfortunately.
