Where can I read about all those parameters such as edge guide, mixed precisions and so on?

[MyaaMyaa]

Also, if I don't type them in the prompt they're not used or some default options are used?
Noob questions I know. I don't know anything about coding
As far I can get gather from the code
action='store_true' means disabled unless typed in
default= means that's the default if I don't type that in.

If you add action type args parameter at shell script, args value is true.
For example,

$ python video_completion.py `
--edge_guide

then, args.edge_guide == true.
