I don't have an Arc GPU, but I guess you wouldn't see much difference on Arc, because Arc has removed PAK encoding and only leavesVDEnc. As I said in my first post, only iGPUs before Arc and Meteor Lake (which use Arc GPU architecture) has PAK encoding feature. So yes, the difference is only...

Yes, on my dell laptop with i5-1345u to do H2640->H265 transcode for 1080p video, using QSV HEVC veryslow preset with global_quality = 24 (~4M bit rate), I got about 50fps using Pak and 320fps using VDEnc. And you should see in Windows Task Manager that video decode unit is max out when using...

Hi, I was doing some research about video encoding quality with HW acceleration and saw your article. Firstly, nice job. One thing interesting I found is that, before Arc and Meteor Lake, Intel implmented two kind of video hardware engine: 1. Es=Hardware Encode via (PAK) + Shader (media kernel...
