here’s the funky thing, if the output profile color working space is the same as the interpreted footage, then no color management settings actually change anything. It’s the same thing as if management is turned on and you go to view-simulate output the same profile, they look exactly the same, nothing to do!
In simple terms, if they’re the same, color management turned on doesn’t do anything, but the downside is that you can’t color correct based off a calibrated monitor, but like you said, you just needed to re-export, so that doesn’t matter either. and you’re right about leaving it at 16bpc. Don’t lose that trillions!!!
btw, a just-4-fun tip is that simulated outputs can actually be burned in creating free-fast-great looking film looks. The effect is called color profile converter. For instance, if you want high saturation, start with a wide gamut or pro photo then strink it down
to a smaller gamut such as SD. There’s fuji stock too etc.
