I test ImageMagick's command that is shown in paperclip logs. ``` $ docker build -t im6 . $ docker run -v $PWD:/images -it im6 bash avifConvert.sh ``` Dockerfile ``` ##...

sample image is downloaded from https://github.com/link-u/avif-sample-images

paperclip also runs `file -b --mime`, but it can't recognize AVIF mime type. ``` file -b --mime kimono.mirror-vertical.avif => application/octet-stream; charset=binary ```
