Problem with Blackmagic pocket 4K Gen5 color in Premiere

Hi!
 
I've been using Gen 4 color on my Pocket 4K for a few years now in Premiere with no issues whatsoever. 
 
I recently upgraded both my cameras to Gen5 and I'm getting a lot of banding on all my Gen5 footage when imported to Premiere. I'm using the official LUT in both Resolve and Premiere Pro.
 
I'm using Mac Studio Max 1 with Ventura 13.4 (22F66) and Premiere Pro 23.3.0. Preview is on Full, playback on Full and high quality playback is enabled. Im also seeing the banding on export. Render and preview in Resolve both look fine.
 
The problem is not visible in Resolve however so luckily it's not an issue with the footage. Please see two screenshots attached where you can see the issue. Top is still from Resolve and bottom with the banding very visible from Premiere.
 
I would appreciate help on how to fix this in Premiere. Thank you!

Correct answer R Neil Haugen

In Premiere, there are settings in the Sequence preview settings and Export dialogs for bit depth ... have you checked those?

 

Premiere used to always use file bit depth, and things like Max Bit Depth in export weren't normally needed. But a version or two back, as noted Premiere expert @Jarle Leirpoll demonstrated thoroughly on his site, premierepro.net ... how the Preview and Export bit depth settings affected both playback and exports changed.

Hi Neil,

 

I simply import the gen5 BRAW files in to Premiere and I can immeadiately see the banding and poor quality. It is accentuated of course if I do any color grading or add any LUTs. So the problem seems to be how Premiere is reading the gen5 BRAW files. Im specifying gen5 since I have no issues with the previous gen4 BRAW files. 

I use the Blackmagic RAW 3.3 plugin. Not the Autokroma plugin. 

I also wrote to Blackmacig support and they suggested that "it is possible Premiere is encoding the footage in 8 bit whereas Resolve is showing it in 10 bit. Perhaps there is a setting for your monitoring within Premiere, but I suggest contacting Adobe if you're having trouble finding the right settings."

 

Im unaware of settings in Premiere where you could choose the bit rate?

I use my BMPCC4K as my main rig, shoot a LOT of BRAW, some ProRes in "extended video". And I'm not having any issue.

 

The BRAW is all handled within Premiere by the wondrous Autokroma plugin, and I've got at this time like 5 presets of different settings. All gen5 of course.

 

I'm wondering though, you say you're using Gen5, which is a BRAW setting, but a LUT ... I'd like to know your entire workflow ... 

Everyone's mileage always varies ...
