If there's any doubt whether these CPU:s should be able to encode HEVC/H. I also tried the other methods of Rate Control but it makes no difference. The issue is seen for both 8-bit or 10-bit output. It's only the 4:2:2 encoding profile setting that has this issue, 4:2:0 and 4:4:4 work as expected. This is also confirmed visually by rendering a chroma subsampling test image ( - note that it requires proper monitoring without any scaling of the HD image). Inspecting the rendered file using MediaInfo ( ) shows that it is 4:2:0 instead of 4:2:2. Rate Control: Intelligent Constant-quality I'm using an Intel Core i9-13900K CPU with up-to-date graphics drivers (31.0.101.4032) on Windows 11 (22H2) and rendering in DaVinci Resolve Studio 18.1.2 Build 6 with the following settings: Driver Model: Intel (R) UHD Graphics 730,Intel (R) UHD Graphics 710,Intel (R) UHD Graphics 770,Intel (R) UHD Graphics,Intel (R) Iris (R) Xe Graphics. Intel Graphics Compute Runtime for oneAPI Level Zero and OpenCL. So one of the killer features of recent Intel CPU:s (10th gen or later) which you can’t get anywhere else in the PC world (except for their new Arc GPU:s) is the ability to render accelerated HEVC/H.265 with 4:2:2 chroma subsampling.ĭaVinci Resolve Studio 18 correctly identifies this ability, but the actual rendered files are incorrect.
