I've spent today with a Venice and a bunch of charts, we also shot lend tests but I'll post about those in glass.



Obviously I haven't had time to thoroughly analyse the tests, I'll be posting EXRs and UHD QT at the weekend



I'm posting now because my first impressions are overwhelmingly favourable. Highlight limits in previous test have been +3.5 stop's today we had 4 with no doubt quality reduction and 4.5 with some compression.

The noise in the -5 test was there but very clean, not messy chroma noise but clean luminance noise that looked as if it would clean up nicely.

The colour response and consistency with exposure change was impressive.



I think we have a new benchmark

Completely according to Geoff, a couple of weeks ago we presented our tests with VENICE at the Cartagena film festival in Colombia. We shot a full day in different places of the city. Now I am preparing an article for Cameraman magazine in Spanish, and my observations are in accordance with what Geoff indicates, the noise at -5 and even at -6 is very clean. Studying the noise we have seen that it is identical in the three channels which makes the chroma noise is minimal. The increase of the ISO up to high values ​​does not substantially increase the noise, in fact, the noise luminance remains almost identical until 5000, and the color is maintained constantly in both overexposures and under-exposures. With this, the shadows we shoot are deep and very clean. Another aspect that I liked the most was the colorimetry, especially the skin tone, which are full of nuances, soft and with a very natural appearance. Soon we will put the video of the tests on vimeo

If it looks good to Geoff, I can send him some clips of the material we shot.

Looking forward to seeing the results of both Geoff and Alfonso's tests.



With its 5 second boot time, 8-steps of internal ND, the added flexibility of a locking e-mount, and dual-ISO. I think the feature set of the camera is really exciting... everything except for it's underwhelming variable framerates, 1-24fps using the full sensor is pretty frustrating, I really do need 1-48/50fps for a basic 2x slowmotion. Above that isn't a big deal, we can bring in high-speed cameras for specific shots and I'm fine with that, but 2x slowmo I need regularly enough that it's an issue. And having to step down to S35mm mode in order to get it will be pretty frustrating.

I really do need 1-48/50fps for a basic 2x slowmotion __________________________________________________________



I couldn’t agree with this more..you can never have enough over cranking. there’s a lot of *Firmware upgrade required.. August. Perhaps they don’t want to announce what they can’t deliver-yet which may be comendable. Is there a roadmap (like they did with the F55) I can’t find it if it’s out there...

The full sensor 6K 3:2(6048 x 4032) is only capable of 24p! It can’t manage 25p? I realise the full sensor mode is not something you would use every day but would be good for VFX and green screen but I repeat no 25p? Since Sony charge an extra licence fee to unlock full frame on the camera I would not be a happy camper if I lived in Australia or Europe.



At more practical aspect ratios such as 16x9 you have to crop to 5.7K (5672 x 3190) and then you can run 25p up to 29.97p. Again I pay Sony the extra licence fee to unlock full frame and I have to crop to get 25p and I run out of puff at 29.97p when Red’s Monstro can run full 8K up to 60fps?



When you add the AXS-R7 Recorder so you can shoot RAW and add the extra licence fees this is an expensive flagship camera and so I do hope Sony can crank some more speed out of it. I have no doubt this will be a great camera and if you don’t need to overcrank your all good but for the majority of work I do the limited fps is a major hurdle.

We shot in FF, S35 3Perf and S35 4Perf at 24fps. I believe that the next firmware upgrade will give speed up to 30fps in all sizes except total FF. I guess I’m showing my age but I grew up with cameras that generally had a limited top speed. I seem to recall it was about 40fps. I’d bring in a high speed camera when I needed it. Now I understand the desire for a jack of all trades camera but you all know the rest of that phrase. I’m happy to use a master of one! I’ll be posting the usual latitude tests as EXR frames and UHD QT soon, I may include the dual ISO 2500 results but as they were using Beta firmware I need to check with Sony. I’ll also be posting some blind tests, hopefully today, and a poll on cml.news, of sequences shot that may be FF, or Anamorphic, or lens expanded or who knows what? You tell me! All shot with the Venice with a couple of amazing looking models.

No doubt the range/noise/etc. is best on Venice, but when comparing the F5/F55/Venice at 0, the F5 seems to me to match the Venice color better than the F55, which is a bit green. Anyone know why?

Noel Sterrett There are some F55’s that have very slightly different calibration settings to most that can result in a slight green shift. These cameras are basically slightly off spec (Sony can recalibrate them). It may be that the F55 camera used for the evaluation was one of these.

I've pulled the EXRs into Davinci to have a play around with them. But I haven't worked with EXRs before, and I'm struggling to convert them from Linear, back to a conventional Sony SLOG3 gamma that I can then work from.



I've been trying different ACES IDTs, and the built-in Linear conversion LUTs in Davinci without success.



I'm sure it's something obvious I'm missing (and I imagine there are plenty of others on here without any EXR experience), so I was wondering if you could give us a quick how-to guide on delinearizing linear in Davinci? (a semi-serious googling of the issue is yet to yield sweet relief).

If you don't want to work in ACES mode, you can use the ResolveFX Color Space Transform to convert to e.g. S-Log3 / S-Gamut3.Cine, so you can, for example, use a LUT designed for that.



You will need to convert both the gamma (linear to S-Log3) and gamut (ACES AP 0 to S-Gamut3.Cine). ACES also has a different white point, so you will need to apply a chromatic adaptation from ACES white (~D60) to D65. I am not in front of a Resolve system right now, so I don't know how (or if) the Color Space Transform effect handles white point adaptation.

Thanks Colin, Geoff and Nick,



Both of those methods seem to work a treat.



Using the OFX tool Colour Space Transform in YRGB mode, lets me get back to SLOG3/Sgamut3.cine (or close enough at least).



And ACEScct + no IDT + rec709 ODT brings me to a neutral Rec709 space in ACES.

Its a shame these weren’t saved as original raw or X-OCN frames (You can extract single frames using Sony’s Raw Viewer). Then you could use the metadata tools in Resolve to adjust the exposure, lift, gamma, gain, shadows, mid and highlight levels used for the de-bayer. I’ve found that Venice material has a lot of stuff way down in the shadows that is easiest to recover using the metadata shadow and lift controls. Same with the extreme highlight range. You get very nice exposure shifts simply by using the metadata ISO control.

Then you could use the metadata tools in Resolve to adjust the exposure, lift, gamma, gain, shadows, mid and highlight levels used for the de-bayer. I’ve found that Venice material has a lot of stuff way down in the shadows that is easiest to recover using the metadata shadow and lift controls. Same with the extreme highlight range. You get very nice exposure shifts simply by using the metadata ISO control. toggle quoted message Show quoted text On 24 Mar 2018, at 11:28, Mark Kenfield < mark@... > wrote:

Thanks Colin, Geoff and Nick,



Both of those methods seem to work a treat.



Using the OFX tool Colour Space Transform in YRGB mode, lets me get back to SLOG3/Sgamut3.cine (or close enough at least).



And ACEScct + no IDT + rec709 ODT brings me to a neutral Rec709 space in ACES.

If you don't want to work in ACES mode, you can use the ResolveFX Color Space Transform to convert to e.g. S-Log3 / S-Gamut3.Cine, so you can, for example, use a LUT designed for that.



You will need to convert both the gamma (linear to S-Log3) and gamut (ACES AP 0 to S-Gamut3.Cine). ACES also has a different white point, so you will need to apply a chromatic adaptation from ACES white (~D60) to D65. I am not in front of a Resolve system right now, so I don't know how (or if) the Color Space Transform effect handles white point adaptation.

I've pulled the EXRs into Davinci to have a play around with them. But I haven't worked with EXRs before, and I'm struggling to convert them from Linear, back to a conventional Sony SLOG3 gamma that I can then work from. On 24 March 2018 at 22:19, Nick Shawwrote:
