Agree, it's no comparison to cDNG at 4:1 even in terms of detail/texture and lack of processing artifacts. 
At least people over in the official BMD forum are complaining as well and demanding for no noise reduction/sharpening setting available.

This examples specifically doesn't show any sharpening halos. You need areas strong in contrast to see it.
Just download some Braw/ProRes footage from the comment section of the video and look at what happens between her skin and jacket, and also how it renders hair...yikes.

 

I've downloaded the files and have them in a UHD timeline in Resolve Studio  outputting to a 27"  HDR UHD monitor via decklink  - I can't see anything  (and I'm looking really hard with a critical eye used to identifying all kinds of artefacts) and I'm seeing nothing, absolutely nothing that I am worried about. What setup are you viewing these files on?

(Just redundant remark from experience with previous models, being little bit puzzled with discussion — if BrawQ0 is meant to be equal to ProresHQ? than there's no place for dilemma: through all BM cinema line CinemaDNG up to 3:1 was always noticeable richer in texture, also in DR and its distribution curve in high demanding situation than ProresHQ, which really is great codec, but not on pair with cDNG for top cinema usage. Without doubt, extremely respectable quality of BM camera image - that for many professionals surpasses that from Red - lays exclusively in, so to say, "deep raw" non-processing transfer... I don't know if at least BrawQ0 keeps that approach...)

Braw 3:1 holds up well on this guy's comparison..

 

 

Thanks for posting... But, frankly, I expected that difference seen on laptop monitor with HD resolution will be less noticeable (i.e. I assumed that comparative qualities of Arri are becoming very noticeable visible just at big screen reproduction)... At least for my eyes, P4K looks waaay harsher in comparison, especially in (second) example in front of the fence where they are at closest matching (in first example Arri was not even properly focused).

They do differ in favour of the Arri for sure, but my thoughts in posting were that the differences are smaller than I imagined they would be, considering the saving.

Actually, I expected that differences will be barely visible on laptop :) (But, of course, my opinion usually is not at all too valuable.) For example, there are some youtube comparisons between GH5(s) and Arri Mini that, for my eyes, somehow manage to make looks even more similar :)

I'd be so glad if the same procedure was applied with CinemaDNG files from P4K...

I thought the Natural Rec709 vl LUT did a good job of making the Pocket 4k closer to the look of the Alexia Mini - that said there is a dynamic range difference that is apparent in day light and makes the Pocket  4k  image harder and more contrasty looking to my eye. I actually thought the Pocket 4k competed nicely for the night shot, as either would do IMHO. I think Sage can get even closer once he makes his LUT available for the Pocket 4k.

What I was most impressed with is that BRAW did not seem to show objectionable softness due to the (b)raw "processing", which is of course a contradiction of terms.

All and all BRAW is not what is hold back the Pocket 4k image - it is the sensor's lower dynamic range.  There is a m4/3 Fairchild sensor that would fit nicely in the Pocket 4k body, which offers an additional 1 and 1/2 stop of dynamic range (14.5 stop and dual 11 bit dacs), so hopefully there will be a new m4/3 camera Blackmagic Camera based on the Fairchild sensor in the (near?) future.

I'm afraid that there could be some sharpening compensation at work to neutralize such compression softness?

While there seems to be quite a few complaints about BRAW from heavy forum users, I've now worked on two high profile Ad campaigns that have used BRAW and haven't heard a DP complain about it. At the same time, I've spoken first hand to VFX guys and girls that have said that they are really happy with the new codec. 

Here's a few pics of the P4K being used as a B Cam on a recent car ad for those interested.

Not sure what I'm missing but after the grade they're almost identical. Like sure, I can tell, but I'll take the $59,000 savings with the P4k any day.

The calculation is very simple. Let's say you use a 50mm. Your metabones reduces the crop by 0.64. 50*0.64=32.

Your Pocket has a crop factor of (in full sensor width) 1.88. 1.88*32=60mm (rounded down). That's pretty close to the full frame equivalent already, but your new crop is (60/50) 1.2 times. So if for some reason you absolutely NEED to shoot at exactly the same equivalent focal length all the time (instead of just framing your shot slightly different), you can take your full frame lenses and divide them by 1.2. 50/1.2=42 equivalent perspective (rounded up). You could do that for all lenses. You want to match your 14mm on full frame's perspective with the Pocket+speedbooster? 14/1.2=12mm, etc.

 

Does that make sense?

Thank you so much.

So, for obtain any full frame equivalent I need to multiply the lens focal by 0.64 and then by 1.88?

For example for a 24mm

24*0.64=15.36

15.36*1.88=28.8 

Si it's safe to say that the 24mm will act similar to a 30mm lens? Thats awesome! This will be my first time using the Metabones Speedboster 🤩

What is your opinion about this?

https://www.bhphotovideo.com/c/product/1443625-REG/angelbird_mp_pcc4k_512ek256c_match_pack_for_blackmagic.html

I already own a T5 512GB and I will probably order another CFast Sandisk 128GB and probably a fast SD card.

What is the maximum bitrate i can shoot with those, and are those enough for a full day of docu work?

and this as a NPF solution? https://cvp.com/product/hawk-woods-dv-bm4-power-adaptor

Braw 3: 1 dobře drží na srovnání tohoto chlapa.

 

 

 Highlight Roll Off P4K is terrible 😞  (and I'm watching it on my cell phone, no big screen!)  the dynamic range is visibly worse than the old BM

and it is unnecessarily contrasting in skin tones.  I won't sell my old BM! 

until the Fairchild sensor returns!  

I haven't liked anything from the new p4k so far, and unfortunately it will remain so.  

The best thing you can do is buy a BMMCC for a few dollars second hand
