Another try with Resolve Studio 17.2.1. 3 X 8K Video streams in Timeline with some Delta Keys.
NVIDIA Render Codec in Main10 available and with the latest NVIDIA Driver (466.47) rendering is OK ... but when involving the 3rd Video stream Resolve is crashing when Output is set to H265-Main10.
The same 8K Timeline is rendered without any problems in Edius X when outputting to H265 Main 10.
