Alexander Starbuck December 8, 2021 Share December 8, 2021 (edited) Hi all, I started diving a bit deeper into color management only recently and have settled on a manual approach, using pre/post-clip groups and various color space transforms. I avoid automation as much as possible (like project-level color management) to learn as much as I can. Another reason for this approach is that I am using a Fuji camera for which there is no support in ACES. Today I tested the camera's low-light abilities by recording a few files internally as a h.265 compressed 10-bit 4:2:0 files, with f-log profile applied. Jut for the fun of it, I recorded the same number of files with exact same settings to my Atomos Ninja V recorder, as DNxHR HQ encoded 8-Bit 4:2:2 no-profile applied files. Once I got into Davinci, I realised that I do not know how to properly set-up color space/gamma curve for my DNxHR files. Does the external device (recorder) receive the camera signal and record it into a codec/container different to the one that the camera saves? This would essentially make the files input settings the same as the Fuji files (Rec.2020 and Gamma F-log). The issue is that by doing so, the image from the Ninja V looks signifficantly more contrasty, especially in the lower ISO ranges. I don't know if this is to be attributed to me choosing the HQ (which is 8-bit) or something else is at play here. Many thanks for all the replies! Alex P.S. If it matters, I hndle my CSTs like so: pre-clip group Node 1: Rec2020 F-Log -> Arri LogC, Node 2: Arri LogC -> ACES cct post-clip group: ACES cct to Rec.709 Edited December 8, 2021 by Alexander Starbuck additional info Link to comment Share on other sites
Tom Evans December 8, 2021 Share December 8, 2021 You should be able to get the same color space and gamma whether you output directly from your camera or through your external device. The container and amount of data could vary of course. 1 Link to comment Share on other sites
Alexander Starbuck December 8, 2021 Author Share December 8, 2021 Thanks for your reply Tom, much appreciated! So basicaly you agree with me that - I am recording the same signal (Rec2020, Gamma 2.4)? Both in my Fuji camera internally AND when it is outputting the signal into an external recorder, which then captures that signal into a different container and compresses it via a different codec?
