For each input value, there is one output value. 1D LUTs assume that the primary color channels (red, green, and blue) are independent, and the output for a particular primary color (for example, red) only depends on the input value of that channel (rather than the values of all three channels).You can use the GenerateLUT node to create both 1D and 3D LUTs: LUTs are generated according to the size of CMSTestPattern cube size. Any recommendations, suggestions, insults are welcome.Generates lookup tables, or LUTs, from color management nodes downstream of a CMSTestPattern node. However, I have a suspicion that i’m screwing something up and it should actually work without manhandling the footage into shape. I’m able to throw an image node on post CM and correct it to prevent clipping and it’s working for the keying and roto that needs to be done on the ungraded. I try type:Camera Log3G10 to scene-linear with the Tagged color space as scene-lin rec 709 and it clips the highlights. and this is where everything goes bananas.
to get it to a different flavor I need to use a Color MGMT, so, put the CM on. sweet… read the autodesk page, this seems to be what I should be doing (firm “maybe” on that one). importing the raw red Debayering Full / Color set to get the information from the file which is REDWideGamutRGB Log3G10. Trying to get a couple of raw shots over to the nuke guys, who want linear (i’m fine with acescg too). Still trying to get out of the hell world frame of mind with RED and could use a little help. So its actually exactly the same process as with Arriraw.
Then you switch flame and nuke to ACES mode, select the correct view transforms (probably sRGB or 709 depending on the displays used) in both of them and now everything will match, yay! for that you use the output-Rec709 ODT as your IDT and also output Linear/AcesCG EXR files Stockfootage you do have to assume sRGB or 709 as you said, I would go for 709 if thats your finishing space but it wont matter much. For Red thats easy, you just switch the decoder settings to IPP2/Log3G10/RedWideGamut.Īfter that you scale down and convert from Log3G1/RWG to Linear/acesCG (you want to scale the shot in LOG hence not debayering straight into Linear). exr files (I personally go for acesCG… even though you are supposed to write aces-2065-1 according to the aces standards…). Generally ACES will just make your life a lot easier, even if you only deliver 709 as you dont need to deal with specialsauce LUTs and viewer setups everything just matches.īasically you want to conform them in some software(resolve,flame.nukestudio, scratch e.t.c) and export your shots as ACES. Do you have more details on the workflow?
