Which you'd expect. Would be interesting to compare it with an Xt3 and A73 maybe

the color/lights gradients are so bad compared to the highest dynamic range camera that even a child would point the finger on that, it's so evident. imho as consumers we can ask to the market to upgrade, evolve faster, to a higher dynamic range sensors on prosumer devices, it's too bad really that only very expansive cameras can solve it. I hope (cross fingers) next poket cinema camera will solve it #blackmagicdropthebombplease

Have you experienced bad color gradients in your own footage on your own P4k?

Shirozina explained better please, so that video show fake stuff?

I can't comment on the video as I don't know how he exposed or processed the images. I can only state I don't see any bad color or light gradients with my P4k as long as I expose it and process it correctly.

I must admit that in the last video - Pocket vs RED - at least in the daylight scene with two lovely dogs, Pocket IMO shows slightly better and more consistent color gradient and whitelight/fallof distribution (although also magenta cast).

I went back and watched the RED vs P4K and noticed an equal amount of banding between the two of them on gradients.  I suspect that it's probably coming from YouTube as my 10-bit GH5 footage doesn't have that problem.  I was watching 4K on my 32 inch display.

Perhaps you could post the video and tell us the timestamp of where you're seeing these terrible gradients?

i would bet on youtube encoding

I also have not seen any substantial banding in the gradients on properly exposed footage with my P4Ks. Banding is more common with 8 bit files, but I haven't had a problem with it on my P4Ks or on my GH5/GH5s cameras when shooting in 10bit. I am with @kye it is probably Youtube compression.

I just went outside and filmed a few short clips in DCI4K - Prores Proxy, LT, & 422. ISO 200 f/11 & ISO200 f/22. I can't see banding in the sky anywhere. Not even in the Prores Proxy footage.

Why shouldn't it be?

ProRes Proxy is 10-bit 4:2:2, one of the reasons I see it as much interesting than H.264 no matter what.

 

Here's an useful chart:

Banding can also happen with low bit rate, but you're right, 8-bit is the limitation there.

Back on topic to something maybe useful - Firmware 6.1 is out ( sorry no BRAW). It has some minor improvements but at present if you are using adapters ( Viltrox, Metabones etc) you will loose aperture control so be warned. I assume they will fix this shortly.....

Shit. Thanks for the heads up. I updated last night but did no testing. Looks like my MB is getting unmounted for the time being.

My Viltrox still works. I'm pretty sure I'm on the v2.3 firmware for it and don't have any loss of aperture or anything wrong.

Yes it's the latest viltrox firmware that's not working with the latest 6.1 BM firmware
