Every now and then when I'm forced to render out an edit so I can color grade in Resolve I like to come back and look at this post and get mad Adobe has never done anything with this.
I would love a modified resurrection of SpeedGrade, sure! As the staffers all know ... lol
The wide rectangular RGB Curves tool they now have in Lumetri is the result of a number of us agitating for that, rather than a square box, over several years.
Now ... if they'd add splines to the curves panels in the Lumetri ...
Now with the different Import/Edit/Export panels in Premiere Pro, I can see this being a new "Color" panel (kind of mimiking Resolve there). The concept art you created really is mind blowing and one can only hope Adobe is looking into this and improves the color grading features. Otherwise people are just going to export to Resolve and possibly convert fully at some point.
@Kevin-Monahan do you have any idea if the color panel will get improved and maybe this concept has some merrit to it?
