![]() After very superficial research, I decided to go with a picture profile with HLG2 gamma and the color mode Rec.709 (NOT BT.2020) for video recording. So, I have a Sony A7C and I make guitar cover videos on YouTube. I can't find a definitive answer on the internet to the questions I'm about to ask. ! īecause I thought I need to change the video color from sony’s slog2-sgamut to Rec 709 by using My_Lut.cube due to my usual pattern in Davinch Resolve.īut you wrote simply process_space: color_timingĪnd it works better than my one.I'm a noob when it comes to color grading. Process_space: Input - Sony - S-Log2 - S-Gamut (2) Before I followed your direction, I wrote the lut (looks) like this in config.ocio (1) Default : ACES - ACES2065-1 means, the whole blender scenes and sequencer works in ACES2065-1?īut suddenly it uses ACES - ACEScg when it comes to rendering the whole scene? Here’s my config.ocio followed by your direction. The way I believe it works is that the OCIO config lists ACEScg as the ‘scene-linear’ role, thus this is the space Blender will render in. Also make sure there LUT interpolation for it is set to tetrahedral. Add the new LUT which now expects ACEScct as IN and goes ACEScct OUT to your OCIO looks with processing space ACEScct.Rightclick the clip on the colorpage and Generate LUT as 33 or 65 cube.Add an ACES Transform node with Rec.709 to ACEScct.Add a CST node with AP1/ACEScct to SLog2/Sgamut and set the rest to none/off except Chromatic Adaptaion.Add a clip to the timeline and jump to the color page.Make sure in Resolve you have set LUT interpolation to Tetrahedral.You can do this inside OCIO but a simpler way I can think of is to create a new LUT in Resolve. The way to set it up would be to make sure the LUT is applied in it’s expected input space and the inverse of the ODT it ends up in should be applied afterwards. It’s just that since the look also bakes tone mapping for that particular display into the image, it’s not as clean as it could be anymore and you wouldn’t be able to effectively deliver for SDR+HDR for example. If you already have a look that is both creative but also converts the image from SLog2 to Rec.709 this becomes trickier but would still be possible. This should give you the exact same result. Then in OCIO you could add it as a look with it’s process space being ACEScct to match the space it was graded in. You’d use the ODT while grading but you wouldn’t bake it into the LUT. So…is there any possible way that we can transfer the sRGB/Rec709 color-based Luts into ACES-cg linear system?Ī custom look for ACES is possible but the best way to do this would be to create the look in the ACES grading space ACEScct which would still be scene-referred. I believe it’s because the luts were made for sRGB/Rec709 based system which is un-linear. Something like… red color over-boosted…etc So basically I’m using like Actor’s video = slog2 + my lut in Davinch Resolve.īut whenever I’m forcibly import my lut into ACES installed Blender, the color goes off. (2) I have my own lut for my slog2 videos (actor’s video). ![]() I guess the Blender automatically changes the video’s slog2 format to ACES-cg system(Linear) as soon as I set the. But since there’s no ‘ODT’ in Blender 3.6, I set the video’s in Blender.Īnd this is how we call ACES IDT I guess. (1) I’m filming the actors via my Sony camera with slog2-sgmut.Īnd whenever I’m importing the actor’s video into ACES installed Blender, I’m getting used to ACES system, and I have couple questions. I’m using ACES 1.2 (ACES OCIO) with Blender 3.6 ![]() Hi, I’m new here, and I’m a beginner of ACES system.
