Up until Resolve 16, everything inside Resolve was meant to work with a rec.709 color space, that’s why when someone would use Aces, they would have all these work-arounds. If you are shooting something on Alexa with 15-stops of dynamic range, funneling it through rec.709 which is more restrictive, whereas if you funnel it through DaVinci Wide Gamut, the possibilities are endless. This is the same with these color spaces.

So what is the difference? Even though you are paying taxes in both scenarios, with the second option you get access to all the money upfront which you can invest and make more, whereas with the first option it is much more restricted. Whereas DaVinci Wide Gamut is like sending an invoice, getting that full amount and paying your taxes at the end. You get your paycheck and your taxes are already taken out. a DaVinci Wide Gamut color space is that rec.709 is like getting pre-taxed. The difference between working in a rec.709 color space vs. I came up with it this morning, so it’ll either be the smartest thing you’ve heard or the dumbest. Now let me explain this in a more entertaining way. But none of those come close to DaVinci Wide Gamut. Then it’s Aces(AP1), then Arri Wide Gamut.

Taking a look from narrowest to widest, you start with rec.709.
