$ man doc/snac.8 | grep strip_exif -A7
       strip_exif  If  set  to  true,  EXIF and other metadata will be stripped from uploaded images (jpg, png, webp, heic, avif, tiff, gif, bmp) and videos (mp4, m4v, mov, webm, mkv, avi). This requires the mogrify (from ImageMagick) and
                   ffmpeg tools to be installed. If snac cannot find or execute these tools at startup, it will refuse to run.

       mogrify_path
                   Overrides the default "mogrify" command name or path. Use this if the tool is not in the system PATH or has a different name.

       ffmpeg_path
                   Overrides the default "ffmpeg" command name or path. Use this if the tool is not in the system PATH or has a different name.
