 ## Estimate film grain script
 The installation of the script creates a symlink to this repo's `./scripts/estimate_fg.sh` so do NOT remove this repo or the functionality of `estimate-film-grain` will FAIL. The `estimate-film-grain` script is a way to estimate the ideal film grain of a video by encoding it at different film grain values and observing at what point does a higher film grain value result in diminishing returns.
 ```bash
-estimate_fg.sh -i input_file [-o output_file] [-l NUM] [-s NUM] [-h NUM] [-I] [-U]
-        -o file to output results to
-        -l low value to use as minimum film-grain
-        -s step value to use increment from low to high film-grain
-        -h high value to use as maximum film-grain
-        -I Install this as /usr/local/bin/estimate-film-grain
