Problem Red One Footages / weird layers in dark areas

[Sébastien Casino]

Hi All,

I'm having problems with some R3D footages. Attached a screen capture.
It shows some kind of layers in some parts, mainly the darker areas instead of smooth fades.
Most of the footages that day, in day light don't have that issue.

It was shot with Red One Not MX, on 4,5K. The problem appears everywhere (RCX - PP - AE) on the Raw image either I color correct it or not.

While I was editing (with native R3D footages), I thought it would disappear during export, but it doesn't.

Maybe it happened to someone here before ?

Thanks for your help.
Seb.

I've had it too. Not sure why? I just blurred it in Resolve.

I think its the camera's way of resolving when there isn't enough information. It usually happens to me when there isn't enough light hitting the sensor

If the camera is massively underexposed there may not be enough color information in all three channels to avoid posterisation as the code values of certain areas are all too close together with not enough variation to create graduated tones - basically you had nowhere near enough light hitting the sensor, and then are raising up those values in post from the sensor native ISO further compounding the issue, where the norm would be to crush the dark areas back down into blackness because they are so underexposed. Compression is likely exacerbating this.

It is a simple 8-bit display issue, on a 10 bit display the banding will disappear.
