Adding Arc GPU with Nvidia GTX960, no QSV Intel CPU system - Does PP really not allow 10bit 422 decode w/DGPUs? 

Read this today..

 

RjL190365 - "...And Adobe currently restricts hardware decoding support for all PCs with discrete GPUs to 4:2:0."

 

What is up with that?

    For Nvidia and AMD GPUs, that's a hardware restriction, not Adobe's. In fact, your GTX 960, as well as all other Nvidia GPUs, do not allow 4:2:2 hardware decoding at all no matter what.

     

    And current non-beta versions of Premiere Pro do not properly support the discrete Intel Arc graphics. You'll have to wait until the next forthcoming major version release for that.

      But can I expect to get the full martrix of QSV decoding/encoding , Xe Media Engine benefits from an Arc GPU in future releases?

      Yes, but Intel's dGPU hardware decoding is different from QSV. Nevertheless, Adobe Premiere Pro will support 4:2:2 HEVC hardware decoding on Intel dGPUs beginning with the next major version release (24.x). Previously, you needed an 11th-Gen or newer Intel CPU that has integrated graphics both present and enabled in order to hardware-decode 4:2:2 HEVC.

       

      As far as the rest of your system, you may need hardware upgrades in the near future: Given the age of your GPU, your system's CPU is likely obsolete (being of the 7th-Gen and older Intel CPU group, which has either completely ended all support including security updates, or soon will end support, and that all of Intel's HEDT CPUs outside of the 10th-Gen Cascade Lake lineup have either already gone obsolete or will go obsolete at the end of this year at Intel itself), while your GTX 960 is now on the brink of being depreciated to "legacy" support status.
