Please download the video I've linked before and take a look. That's what the camera does in standard settings. Maybe they turned down temporal filtering a bit already, because your example looks nowhere near as bad as the footage I've taken a few months ago at photokina.

Thanks for the test. Seems like underexposing helps preserving detail (less compression) but temporal filtering causes some strange "static" noise, fine and flickering pixels (instead of actual detail) and smear when subject or camera is moving slowly - the same happens on the GH4 above ISO 2000 and A73 above ISO 1600 - but both show even more ghosting. Both the X-T3 and Z Cam E2 (which is way worse though) show this issue at every ISO. Still the X-T3 looks like a better cam in low light than the A73 does which is a complete mess in higher ISO due to strong temporal filtering. But honestly, looks way better than the other footage another person on YouTube shot and uploaded (both internally and externally in ProRes) using sharpening and noise reduction at 0 and interframe nr turned on. https://drive.google.com/file/d/1sb0MH4soxt-Kqtf0jiYXc4dN0u5U-iFD/view?usp=sharing Overall, I would actually use this camera up to ISO3200 (when slightly underexposed and NR/Sharpening at -4 and interframe NR off). Wondering how HLG looks in different exposures. Expecting more detail even

Didn't try HLG on the camera, only Astia, Eterna and F-Log. For DR800 ISO640 was minimum. And in my tests ISO6400 was just horrible. Would rather have some grain than this.

ISO6400 on this camera is rough lol Skin didn't have any texture even in great lighting using anything higher than ISO640 lol. But then I'm working on 27 and 32" 4K screens.

Max Yuryev noticed it in his first hands on review and was complaining about it - but didn't know it's the "new" temporal noise reduction causing the so called paint-brush effect. Right now the A7III and RIII have the same issue the GH4 has in low light lol. At least the GH4 turns off noise reduction while recording externally...

I saw a video on YouTube about external recording ProRes on the X-T3. The external recording source files showed even more of the temporal filtering issues, here's a download-link: https://drive.google.com/file/d/1sb0MH4soxt-Kqtf0jiYXc4dN0u5U-iFD/view?usp=sharing The GH5 (after firmware 2.0 and lots of complaints) and the A7sII don't suffer from these issues. The GH5(s) only has to deal with oversharpening still. The Z cam E2 will offer a switch to disable temporal noise reduction soon. Fuji and Sony on the other hand don't bother fixing these problems. I honestly don't understand why many cameras show the exact same artifacts my old Grundig CRT TV showed in the late 90s... ?

I really wish they abandon their postprocessing "tricks" and go back to no processing like they did with the A7sII. The image, especially using an external recorder, was so much better on the A7sII. Kinda sad what they went with the A7sIII which looks horrible above ISO1600 - not because of noise but static textures, ghosting and detail loss while the A7sII showed lots of detail up to ISO25600.

That's the test where the A73 (wax skin above ISO1600) and especially X-T3 (wax skin in daylight even) would look bad in comparison. Especially when the P4K is set to Raw recording and sharpening set to 0 and highlight recovery turned on in Resolve. Tried the X-T3 and even though noise reduction is set to -4 (min) and interframe nr is off, there's no texture left on skin. The temporal filtering cannot be turned off.

And so does Blackmagic: 16 bit linear sensor readout -> 12 bit non-linear logarithmic raw. Exactly the same technology behind since the BMCC except way higher quality components, sensors, filters etc on the Arri Alexa. Probably the reason why the noise floor is so much higher on the GH5s despite using the same sensor. Shooting in RAW and downscaling in post using a bicubic filter will give you way smoother footage. But honestly wouldn't downscale anyway, basically finished every project in 4K since 2014 and stuff still looks good on big screens . ?

So does the P4K

Arri Raw is 12 bit as well. The magic word here is: logarithmic yep and the halos get twice as big lol Exactly the same issue I have on my GH5.

That's what it is. Had to deal a lot with getting rid of the negative effects of internal sharpening on the GH5, but if you want to really get rid of these you either blur actual detail or even produce other artifacts. My next project will be entirely shot in RAW. So no more issues with that just creamy footage.

In ProRes it clearly does - even when turned off, you can easily spot sharpening halos around high contrast edges such as trees, lanterns, roofs etc... Also there's noise reduction and other filtering going on using ProRes which causes a low contrast texture loss (which is not as extreme as on Panasonic GHxx, Fuji X-Tx or Sony A7SIII or A7RIII). With the Pocket 4K Blackmagic finally went the route basically every other prosumer camera went: a full blown processing pipeline. Thankfully these problems completely disappear using RAW when sharpening set to 0 in Resolve. That's why the Pocket 4K is claimed to be a videoish looking camera - which at least when using ProRes is true.

Kinda reminds me about the RAW update for the NX1. ?

You just need to shoot RAW and turn sharpening down to 0 in Resolve and the sharpening is gone. ProRes looks bad and digital in comparison on the P4K sadly and 1080p still shows sharpening halos while UHD/4K in RAW doesn't. Add a diffusion filter and the moire/aliasing is gone as well and it looks even smoother.

Not that I know of. Really hope to see a fix to color science 4 soon (BMD UMP and Pocket 4K). Would recommend not to shoot any ProRes footage at the moment as the issues are baked into the footage then. Using raw it's not a big deal.

It's not a camera issue (well it kinda is recording ProRes at least). Take a look at this sample BRAW file from Blackmagic from the UMP. Same issue using color science 4 https://downloads.blackmagicdesign.com/products/blackmagicursamini/blackmagicraw/Blackmagic_RAW_Note_Suwanchote_Wedding_Dancing.zip

Nope, that's not it... Panasonic should have released the V-Log update out of the box which may even be crippled V-Log L again with limited Rec709 gamut instead of V-Gamut and forced sharpening of course - but we'll see. If I want bad autofocus but great video quality I would rather buy the Pocket 4K with a Speedbooster XL and shoot raw. If I want high resolution photos I would buy the A7III which is an 8 bit cameras as well. Should wait for the Sony A7sIII then if full-frame is a must unless they mess it up the same way they did with the A73 and its horrible temporal noise filtering starting above ISO1600. The A7sII didn't have this issue at all - neither does a Canon EOS R and 5D MKIV. According to the sample footage I've seen so far at least texture isn't a problem, lot's of skin complexion is captured. If it was a Fuji all low contrast texture would be lost. Yay waxy skin lol.

Better DR and color out of the box as well and little to no processing at all. Still waiting for BMD to fix color science 4 though (red clipping).

So basically nothing since the initial firmware (I've tried on Photokina last year) and an external recorder doesn't help either and H265 doesn't cause waxy skin with little to no definition and temporal noise reduction fighting against any signs of texture. Well - if you like it, it's all yours... So disappointing.

Probably should rest until BMD fixes their color science 4 lol The red clipping is dreadful and appears on every camera using color science 4 - even on Blackmagic's own BRAW samples.

Had the viltrox as well for a day. Sent it back immediately. The Aputure Lens Regain and Metabones adapters are way better.

8K So basically 36MP on a 4/3 sensor. No thanks. My phone is already noisy enough, dynamic range suffers a lot as well. 10MP on 4/3 is perfect (P4K, Terra 4K, GH5s, E2).

Finally found some footage with sharpening set to weak (which should mean it's off). Looks great to me, but still looks like it's gone through some temporal noise reduction (could be the codec as well though) https://drive.google.com/file/d/14FoFmymWaGRdAkOC24Zzn4MdAbLxDvr6/view?fbclid=IwAR2hlml1Ysb3x3RX1U4LdQu0zFmC33cmpy_JMOkmH5uY9jofHgHVr76ftTo

Just make it more dramatic then? @androidlad care to upload some uncompressed footage? Wondering about skin above ISO1600 (lost lots of texture doing my first tests)
