Hardware Acceleration Dropped with Upgrade?

  • April 11, 2019

I appear to have lost the ability to use hardware acceleration when I export with Premiere Pro. I was able to use hardware acceleration with previous versions of Premiere Pro. I haven't changed any of my hardware. I've looked around for solutions and tried a number of things, none of which worked. Please help!

System and versions:

Premiere Pro v13.1

Windows 10 Home version 1809, OS build  17763.437

Graphics card: GTX 970, GeForce driver version 425.31

Happy to supply additional information as needed. Thank you kindly for your assistance!

    It can be very confusing.

    There's Hardware acceleration, Software acceleration, and ... repeat/rinse.

    First, there's GPU acceleration through the Project Settings panel's Mercury Acceleration option. If you have a usable GPU, and it's set to anything but "software acceleration", then Pr will use the GPU for everything it actually uses the GPU for. Which is only the things on the GPU Accelerated List. Color, Warp Stabilizer, significant resizing between timeline/export frame sizes, that sort of thing.

    Second, there's "Hardware/software" acceleration concerning the H.264 abilities of the CPU and whether it has the Intel QuickSync chip included and enabled, and this is shown in the Export dialog's "summary" section.

    That tag in the Summary section of the Export dialog confuses people so often ... they think "software only" means their GPU is disabled or ignored, but that has NOTHING to do with the GPU. Only whether the computer has QuickSync onboard and enabled.

    And no, the GPU is not involved in general exporting UNLESS something off the GPU Accelerated List is involved, and then, only as the CPU calls for it.

    That was helpful! Turns out my PC had stopped enabling Quick Sync from the CPU. I changed the BIOS setting from Auto to Enabled, and that did the trick.

    Looks like the 1089 Windows update handles Intel graphics drivers differently, so that's probably the culprit. But I can now select Hardware Acceleration when I export. Thanks for pointing me in the right direction!

    This stuff can be amazingly dense to puzzle through. Glad you got it sorted!

    I get great GPU performance when creating Cineform 720p proxies, from 4K UHD AVC files.

    Here's screenshot of Task manager I captured during the process:
