Interpretation issues of Fujifilm video files in Davinci Resolve, Premiere Pro and Final Cut Pro In: Cameras Posted April 26, 2019 To me this seems to be the exact same issue as the one described in the video, but with different matrices. There are 3 matrices to go from YUV (YCbCr to be technically correct) to RGB. For SD usually the BT.601 matrix is used, for HD the BT.709 matrix, and there's the BT.2020 matrix which you can see in HLG for example. That doesn't mean that you can't encode an UHD resolution log format with the BT.601 matrix, Fuji does just that. And as androidlad mentioned, you can have Alexa log encoded with the BT.709 matrix. To have the right colors in RGB, you have to use the correct matrix. Then you can delog your footage and convert color space etc. But all this comes after the YUV->RGB conversion.
