Does this sofware allow for the output image to be reveresed when required?
Yes, you can toggle flipping on the main window and on copies of it on other screens, independently, at any given point in time. That’s assuming that by “output image” you’re referring to the teleprompter’s output, and by “reversed” you mean flipped horizontally or vertically for use with a beam-splitting mirror.
If by “reversed” you meant reversed scrolling, yes that is possible too. Press “I” while prompting and this will reverse the prompter’s direction.
