Setting Eye Precision Mode
From version 1.3.8 on there are 2 modes available for Eye Precision - Smartphone or Goggles
Smartphone mode adjusts the pupil threshold setting to allow for more light variation in a video, and applies more noise cancellation, as well as allowing for hue setting adjustment to work with a range of iris colours
Goggles mode is preset for greyscale videos, with blink detection possible (active by default, can be deactivated under advanced settings)
Choose your mode in the menu bar - at the top of the window in Windows, or at the top of the screen in MacOS
