  1. This discussion looks similar to Sigma Fp topic regarding their raw DNG having some issues. Problems in downscaling 6K to 4K Raw? Very interesting. Still waiting for my Z6 to come back from Nikon. Will do some testing. Although I don't have a pro resolution chart at hand either.
  2. Arguably, film still has better color than ANY digital camera at any bit depth. So using that argument to justify 8bit camera is rather weird. But of course, you're free to shoot on 8bit camera, especially IF you like its sooc image :).
  3. I'm powering it from the nucleus M handgrip which is attached to the camera cage and also used to control the motor. I made a custom USB to lemo cable for it. Maybe Tilta has a ready made cable now. It gives 7.2V. The higher the better as the torque depends on the voltage. So standard 5V is not the best solution.
  4. Sorry, but if one doesn't see advantage/difference in using 12bit color then I guess one is better to keep using something like Sony A7III with its glorious 8bit log.
  5. Looks very very good. And this given that a non-optimal path is used - footage converted to Sony log with LUTs intended for Sony cameras applied... Nlog support is said to be coming to FCP soon.
  6. Amazing job. Wish you could do it for more cameras. I could provide you with samples of most of them side by side with Alexa, and you just do the math. How about it? :).
  7. When comparing DR you should go both ways - over and under. Otherwise it's pretty useless. Log curves are mapped differently, so "normal exposure" as a starting point will never be the same for both cameras.
  8. Yes, their LUT is no good. I wonder who did it for them. Don't want to be hard on Nikon, they are new to this, but still. They should hire some knowledge into their team regarding video. Neutrals not staying neutral is not that bad in my book though... At least in my attempts to match Alexa I couldn't find a way to come closer without some cast in the neutrals. Your LUT, Attila, stays true to the neutrals, but leaves too much of the Z6 N-log inherent "greenishness", at least to my liking. And I prefer even gentler roll into the shadows.
  9. I believe all attempts at [pseudo] log at 8 bit sacrifice too much color..
  10. This one probably hasn't turned sharpening down in camera.
  11. Hi. Right now the only advantage you'd get with Panasonic S1 versus Nikon Z6 is shooting 10 bit 4:2:2 internally. That is, if you want to be extremely undercover with your gear, just a small camera in your hand, no ext. recorder etc. Oh, and that 4K 60p that is so important to some. Not me. Other than that they share the same sensor. Contrary to what some guys keep repeating here, Nikon's Z6 external output is very high quality 10bit, giving 12 stops of dynamic range. Color science is actually excellent. I've yet to do a comparison with Panasonic S1, but I managed to tweak Nikon N-log colors to a LUT that matches Alexa colors very closely. Skin tones look great. Overall, this is a great camera that is unfortunate to be built by Nikon. Which is not regarded as a company you'd associate with video. It's amazing how Sony's A7RIV manages to get attention while offering nothing even close to Z6 in video dept. Apparently it's all about brand names...
  12. When I asked Atomos about this at Cinegear in June, they pointed to a Z6 on their stand with Ninja V attached and showing "prores raw" in the corner of the screen. The guy told me "I don't know, it's ready and up to them when they release it". So it could be all sorts of things - like Andrew pointed out. I for one would hope it's just waiting for the competitors to announce their stuff first.
  13. Alexa rec709 based monitoring luts that is. I'll try to shoot some side by side Alexa and Z6 over the next week. Was asked to do this over on dvxuser.
  14. It could always be better, I guess. But seriously, how many of you have expected we would talk about any kind of raw video in a mirrorless so soon? 12bit prores raw out of a full frame mirrorless camera - I'd say this is the "good enough" line I draw.
  15. I could never understand trying to rig those small DSLR/Mirrorless into a shoulder rig -type configurations. With new products from Tilta, etc. now things can remain small, and yet have everything included. With different style handheld, that is :).
