Come back to Mari Mike

actually helped me, now i know what sRGB is and why i dont need aces ^^ thank you

Yes, its a nightmare of missinformation. And below that there is a lot more to unpack with regards to color (as a perception!) and the concepts of "scene" and display referred imagery/ image data. Wrote my thesis on that topic, analyzed and created a lot of signal path diagrams and had a lot of expert meetings trying to get a good angle from the color scientist and image enginieering community. For starters, instead of calling anything gamma, you should define what kind of transfer function you are referring to. And even then, there is a deeper rabbit hole to get into, when looking at the origins and problems with all of our current models (even the newer CAMs) - CIE colorimetry with our standard observer ("statistical fiction" as Poynton calls it), luminance, luminous efficiency function, lightness mapping and so on. There are really many layers now, but it is interesting to see everyone struggle, including myself. "Color" is not a solved problem after all!

You are right that the video is a bit oversimplified and that it continues to use some of the bad phrasing common in our industry. But I still think that it's doing a better job than many others :) Also, without meaning any offence, you are applying similar missconceptions and making wrong statements adding even more to the confusion... :/ Let me explain: Colourspaces are defining an EXPLICIT connection between colors (hue, saturation and brightness!) and the mathematical values stored in a file. This means that they NEED to define the brightness response and thus the EOTF (what you called Gamma). And as such they are either linear or non-linear. What you seem to be calling a "colorspace" is actually the gamut, which is just one of the three factors we typically use to define colorspaces. (The Gamut is commonly defined by three primary values, which are used to draw the famous triangle on the chromaticity diagrams.) Colorspaces as a whole are defined by the "Gamut" (the range of available chromaticities (colors without consideration of brightness)), the "Electro Optical Transfer Function" (short EOTF) (you could also call it the brigthness response...or as you called it: Gamma.. which is actually just a specific type of basic non-linear EOTF.) and the "white point" (this defines the values for the neutral color). Your confusion likely stems in the whole sRGB naming mess... There is the "non-linear sRGB" colorspace.... (often just called sRGB, just like in this video) the "Linear sRGB" colorspace (often just called "linear"...horrible name in my opinion, as it's just an adjective that fits dozens of colorspaces...), and well then there is the Gamut used by both of these, which has it's own separate name but many people also just call it the sRGB gamut.... (The Rec.709 colorspaces use the same Gamut and "Linear Rec.709" is even exactly the same as "Linear sRGB" as the only difference between (non-linear) sRGB and (non-linear) Rec.709 is the EOTF.) There are plenty of colorspaces explicitly linear. There are even two completely separate yet both linear colorspaces within the ACES configuration! ACEScg and ACES 2065-1 They both have a linear EOTF and the same white point (close to 6000K so very close to D60), but they do have separate Gamuts (the thing that you called colorspace). (ACES 2065-1 uses ACES AP0 primaries to define its gamut, while ACEScg uses ACES AP1 primaries.) And to run home the point that having the same Gamut does NOT equal to being the same colorspace. There are multiple ACES colorspaces that use the AP1 primaries.... ACEScg, ACEScc and ACEScct all have the same Gamut (and white point), yet are all considered separate colorspaces due to their distinct EOTFs. Out of the bunch, only ACEScg is linear! Sorry for nerding out for a second 😅 I hope this helped clear some of the confusion 😊 and hope that you have a nice day!

@@andreasmischok8523 I was thinking for a second you were replying to my response. :D

@@BlackPantherElite oops xD my bad.. should have mentioned the name 😂

​@@andreasmischok8523hi, total noob here so I apologize if this is silly; you mentioned that rec.709 linear and sRGB linear are identical besides their EOTF, but if they are both indeed linear and have a straight line proportion then shouldn't the EOTF be the same? i think I'm confused as to what the EOTF is, is it not the correlation curve between the colour's actual luminance and the output? or is that simply called the gamma curve 😅
