Margus Voll November 23, 2018 Share November 23, 2018 Hi. I wonder if you see ever material breaking up while using aces? What i mean is if shadow gets rather deep i get insane snow of super saturated pixels like noise in another platform. So i wonder if BL does the same thing or if it is handled better? My assumption is that non aces tools do not do that because of the clever math. Link to comment Share on other sites
Anton Meleshkevich November 23, 2018 Share November 23, 2018 Still didn't finished any project in ACES. It looks noisy. Dark saturated colors get clipped. And I would also like to know if it is only Resolve thing. Link to comment Share on other sites
Jussi Rovanperä November 24, 2018 Share November 24, 2018 Most of the Aces issues seem to be caused by AP1, it's small compared to camera gamuts like AWG or RWG, so colors that are out of gamut for AP1 end up in strange places. Link to comment Share on other sites
Margus Voll November 25, 2018 Author Share November 25, 2018 Maybe it is application based then as well not just system based? Link to comment Share on other sites
Andy Minuth November 25, 2018 Share November 25, 2018 @Margus: Are you using ACEScc or ACEScct as a working space? ACEScc might make noise in under-exposed shots a lot more visible, because it increases the contrast in the blacks if you push up a shot heavily. Curves like ACEScct, T-Log, LogC, etc. avoid that by using a toe in the shadows and are better suited as working space. The out of gamut colours that Jussi mention need to be dealt with accordingly. The T-Log / E-Gamut working colour space is optimised for typical out of gamut colours of current cameras. Alternatively working with the native primaries of the main camera sources (LogC / WideGamut, 3G10Log / REDWideGamutRGB, S-Log3 / S-Gamut3.cine, V-Log / V-Gamut, etc.) might avoid them on input side. But when you are running into out of gamut artefacts on the output side (e.g. in the RRT) during grading you need a tool to deal with that. In Baselight we have the CompressGamut tool which deals with out of gamut problems in both cases. It gently moves colours back into a target gamut without affecting the overall look. And it can bring back even negative code values, so it also works nicely in smaller working gamuts like AP1. Link to comment Share on other sites
Margus Voll November 25, 2018 Author Share November 25, 2018 I have been now mainly on cc. I remember this from the demos you gave me ate IBC the gentle approach. This was the thing i tried to hint as well "gently". :) I will try with next job how it would feel with cct. Link to comment Share on other sites
