Red pixelation appearing in exports

Hello,

I have an issue with my exports showing a strange, red pixelation in some of the darkest points of my images (Notice the arm). It appears regardless of export settings, making me think it is a source image problem. However, I have used a lot of footage from the same shoot and this problem seems exclusive to this setup and shot. It is also only visible after my color grading and after exporting. It is not visible at all in my project. I have tried several export settings, from mp4 (which is the deliverable requirement) to ProRes and DNX

It seems to get less apparent as I lighten the image, but the client is not very happy with the lightened product and wanted it around this level of darkness. The source footage I am using is Pro Res LT. Sorry I can only post the above cropped image due to privacy concerns.

Please let me know if anyone has encountered this or has any suggestions.

I have found the issue and fix.

The issue was I had selected the "High Dynamic Range" option on the Lumetri Color effect. I think Premiere had trouble dealing with the darkness of the image and the color pass. Simply deselected the High Dynamic Range option and the image quality improved.

michaelp,

ProRes LT? Which camera are you shooting with? Or is it an Atomos or similar device you are recording to?

Thanks,
Kevin

The ProRes LT was what was handed to me, but the original footage was shot on Alexa I believe. My concern is that there was also a Rec709 LUT applied, but I simply only had access to the compressed footage to work with.
