Here's my proposal for matching the two cameras. And a grade test. No LUT was used.

I really like the first one. Here are two other proposals.

Very close. What jumps out at me is a difference in the blue of the sofa cushions in both and a difference in the saturation of the reds in the second still.

Here's a Flog shot with an XT4 (trimmed copy of the original file). https://drive.google.com/file/d/1atTlmtWQYmRevkfXwsM4ihnyR7ARMLvf/view?usp=share_link And my grading suggestion.

https://www.mir.com.my/rb/photography/companies/nikon/nikkoresources/zoomsMF/2550mm.htm There's the Nikkor 25 50. I bought one, on eBay, 2 years ago, for $100. It only opens to F4 and is really good from F5.6. It is parofocal with three rings; aperture/focal/focus. I've already posted a short video test on XT4 (apsC) on this forum. https://vimeo.com/manage/videos/397291419 Password : nikkor2550

Yes I mean the Film look LUT from Resolve (stock emulation). I don't use the FUJI LUTs to delog the Flog, I prefer color management.

If you like this kind of grading, the Resolve FUJI LUT could be a good start.

About the chroma smoothing issue, my only problem with the XT4, was that at a certain distance, on a face, the teeth and the white of the eyes tend to take the color of the skin, as Attila Bakos showed on his example with the red bricks joint. With the XH2S in ProRes HQ, it looks much better. And the Flog2 is absolutely amazing. Currently Flog2 isn't in Resolve so I'm using a CST with Gamut : REC 2020 and Gamma : ArriLogC (because the gamma curve of ArriLog C and Flog2 is almost identical, but not the color space) I had tried to tinker with a node in Resolve that acts only on the red channel to fix the chroma smoothing issue but no really interesting result.

It's possible that the noise is like dithering. https://en.wikipedia.org/wiki/Dither

Yes for 4K the bitrate are very similar (I am around 780Mbps for ProRes HQ in 4KDCI) But for 6,2K I have a bitrate of around 2300 Mbps with ProRes HQ. This is really different from the 720 Mbps of H265 (Angelbirds SE 512GB cards are very good at a reasonable price, I got some around 180 euros) https://www.angelbird.com/prod/av-pro-cfexpress-se-type-b-2919/?category=238

Thank you for this test. I would have preferred to see ProRes HQ instead of H265. Did you delog the Flog2 with Fuji LUTs ?
