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. These work with Arc A-series discrete GPUs, Iris Xe MAX discrete GPU, and the Iris iGPUs found in Intel Core processors from the 11th Gen onward. 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). Intel Graphics today released the Arc Graphics GPU drivers 31.0.101.4146 WHQL. 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: 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.
