For an introduction and the list of main parameters to get you started, refer to the earlier section at: https://gist.github.com/Glidias/b15b51598ae643bab9dbc7aa12fe62ed
These doc only covers anything workflow specific beyond file/json-based stuff.
There is a switch to adjust between switch numbers 1-3 for shift settings (Low, Medium, High) above the Sampling workflow group . Default is 2 for Medium but you can change this default depending on the nature of items in your batch source folder. The shift will increase for resolutions moving closer to or at 720p resolution (determined based off the shorter side of the output dimensions).
