Video renders with slight color differentiations (noticeable)

[Marketing14]

Hi, 

I am having troubles with rendering a video that uses a color matte (#181818 hex code), when the video is rendered it leads to slight variations of (#181818 - #171717 hex code), it occurs across the entire video and happens in a square like form, it can be very noticeable when looked at due to how much of a variation there is. 

Variation 1

 

Variation 2

Compare when both seen at a video

Hi @marketing14,

I read your message. You didn't mention your export settings. Is this H.264 or HEVC? Try a 10-bit 4:2:4 or 4:4:4:4 delivery codec like ProRes 422 or higher. Let us know the results. I hope we can help you.

Thanks,
Kevin

If Apple ProRes is not available, you can also consider other high-quality codecs like Avid DNxHD/DNxHR or the GoPro CineForm codec.
