“My export settings go to an Apple Pro Res 422 file, 1920×1080, 29.97 FPS, Square Pixel.”
you say you are EXPORTING to these settings.
are these the settings of your working sequence, or is your working sequence something else?
“I have used multi colored fonts for over 3 years on this program and come February 2016, this just stopped happening”
so what else has changed?
you say you have a new computer. is that your work computer?
any other changes to the way you work?
have you used THAT red before, with THAT font?
are you scaling the text up at all?
i notice that people ask you sensible questions to help them help you,
but you rarely respond.
