I think dark rendering has more to do with the output device (projector, monitor) than the video encoding. So, changing the output device would have the greatest effect on darks. I'm not aware of any encoding methods to increase dark details except just adjusting the brightness and contrast.

Hello and welcome to LQ.

I agree, kinda hard to get detail out of nothing.

May end up cutting out areas that need edit and use filter. https://superuser.com/questions/9281...mplex-contrast

Increasing the colorspace and bitrate can help with dark detail. But you'll have bigger files and higher bitrates. When I screen capture I use yuv444p since anything less and yellows become some cream like color. When I view content with a lot of darks, I often adjust xrandr to fiddle with brightness and gamma. Depending on the display device, brightness at about 0.7 and gamma at about 1.2:1.2:1.2 plus or minus. The values vary depending on the display device. Some libxca routes too if you have calibration values for your display.
