Paid version works great and is WELL WORTH THE MONEY!
I performed a number of video tests with my
M2P and found for me the absolute best quality UHD video is when recording mode set to HQ and HLG with H265 of course. Style set to 2-1-1 (pushing past the internal noise reduction algorithms - they tend to create water color effects when set to 0 or below in this first version the codec. The sensor is very good and very low noise to start with, so boosting the sharpness, contrast (just a little) and color (just a little) produces really good results with incredible clean details). Recording in HLG essentially allows one to grade the video in HDR mode extracting the maximum dynamic range in Resolve and then let resolve produce the non HDR output.
My current Resolve project settings are:
UHD 2160p at 29.97 fps
Enable HDR metadata over HDMI
Frame interpolation (used for tracker and noise reduction in this case) set to "nearest, Enhanced Better, and larger")
Color management set to: Davinci YRGB Color Managed.
Set "input color space" to Rec2020 HLG ARIB STD-B67
Set "timeline color space" to (the same)
Set "output color space" to (the same)
Set HDR mastering to 1000 nits
The rest is pretty much left at defaults.
I created a LUT that I use for basic grade and the fine-tune it as needed.
I push the "Mid-tone detail" to 40 (+40) and push the saturation to 60 (+10)
I do add an initial noise reduction node where I set the temporal noise reduction to 5, better, small and 50 with motion to 100.
I also add a final node using the "Soften & Sharpen" FX setting the small texture to 1 (max) and the remaining medium and large to 0 (no change). This FX does an amazing job in with this setting offsets the very small amount of softening that results from the temporal noise reduction.
I render the project using mp4 (standard 8-bit) set at best, maximum 150Mb/sec. Viewed on an LG 4K/UHD OLED TV - absolutely stunning!
