In reply to Malick. Venice 2 is ranked higher in DR by CineD (significantly better in hi-base).

Is 6K FFc -> 4k pipeline for 1:1 chroma resolution (for lack of a better term)? That 1.07 crop factor is odd, what else could it mean?

In reply to Dan Hundley. Hello Dan, rolling shutter is always linked to recording mode. Yes, it has 7.9ms but in 4K S35 crop mode.

On your rolling shutter rankings the Burano has 7.9ms I believe and is ranked near the best. Here in this test you say rolling shutter is on the high side and your lowest reading is 14.8ms and that’s in FFcrop 6K 60fps. Can you explain?

In reply to Jonathan Pais. The Latitude test is same as the original Arri Alexa. If you can see better than that good luck to you.

In reply to anon. Raptor clips at 2 stop over. You have to see the latitude from both sides.

In reply to Gunther Machu. Yes, I understand, but at least in Sony, and I believe in other brands as well, the resolution delivered with red light is far below what is expected. I think each brand handles this differently, with varying results. I have verified this with the Sony a7S III and a7 IV. I could send test files made at home.

In reply to Jonathan Pais. Hello Jonathan, yes we asked. But we always got a general reply, never a specific one.

In reply to Martin Chebaia. Hello Martin, do you mean the standard relation between Luma and RGB (e.g. L = 0.299*R + 0.587*G + 0.114*B - as you can see blue has the lowest resolution, red a bit higher and green by far highest)? Or something specific to Sony?

It would be good to add a sensor resolution test with colored light sources. I have noticed that many cameras, especially Sony ones, completely lose sharpness when the light is red, somewhat less with blue, and significantly with green. I think this is relevant information in current productions where there is so much color. I don’t know why I don’t see people talking about this.
