3/22/2023 0 Comments Lutcalc not generating lut![]() My current ACES Rec.709 3D LUTs expect that the source is interpreted as full range (with the exception of Z Cam ZLog2, I've seen both full and limited range files). There is also a lower contrast version for each of them, if that's what you prefer. (The new Z Cam and GoPro LUTs go from -3 to +3.) They range from 1 stop underexposure to 3 stops overexposure in 1/3 stop steps. If you like the ACES Rec.709 look but you want to stay in Davinci YRGB mode, I give you a bunch of 3D LUTs that emulate this look. ![]() However, when using Z Cam footage, leave that option on "Auto", as I've seen both full and limited range ZLog2 footage, and Resolve handles both correctly. It's also important that my IDTs expect full range input, so select all your clips where you plan to use them, right click, and at Clip Attributes choose Data Levels "Full". Do the same for camera B and so on.Īlways do this in the media tab, never apply an IDT at the node level! Select all the clips from camera A, right click, and at DaVinci CTL choose the IDT for camera A. If you use footage from multiple cameras, leave Input DaVinci CTL at "No LUT selected", click Save and go to the Media tab. If all your sources are from one camera, navigate down to Lookup Tables, and at Input DaVinci CTL choose the IDT you uploaded. Leave ACES Input Device Transform at "No Input Transform", and choose the desired ACES Output Device Transform, like Rec.709. Then start up Resolve, go to Project Settings/Color Management, and choose one of the ACES working spaces at the Color science selector. The IDTs are created in Davinci CTL format and should be uploaded to the folder containing your LUTs. ![]() Since the white papers of log picture profiles usually contain all the necessary information to build an IDT, I decided to create some of these. These are the scripts that prepare your footage for ACES.ĪCES already supports a lot of log picture profiles from different cameras, but there are still a few missing. ![]() If you work in ACES, you are familiar with Input Device Transforms, or IDTs. ![]()
