My CPU is an AMD 5600X. My test video is 1080p 30fps, I’m trying to bring it down to 480p using AV1.
This is my first time playing with AV1. I bought an A310 to play around with because I read that the hardware encoder was faster than software, albeit lower quality and slightly larger.
Quality isn’t important to me, I have 700gb of 480i video that was saved at 1080p and inefficiently encoded, I want to reduce its size dramatically.
I’m using handbrake on Windows, and I chose AV1 SVT at first, and I average about 150fps, sometimes 120 sometimes 180. My CPU sits at 100%.
But if I choose AV1 Intel QSV, I average only about 40fps. And the GPU sits at 68%.
What am I missing? Thanks in advance
Edit: I found a thread from a year ago saying that encoding performance dropped after driver 4887, so I rolled way way back to 4885 from October 2023, and my performance almost doubled to 70-80 fps. But this is still far worse than SVT on CPU alone.
I read about a bug where the whole card can only be utilized if running two jobs simultaneously, so I tried this. The second job runs much slower, about 10-20fps. But that does bring me closer to 90-100fps combined, sometimes 🤷♂️
Something has got to be wrong, or maybe I’m expecting too much performance for the job I’m doing? I don’t have any special filters set up. You’d think encoding 1080 to 480 would be lightning fast.
This is explicitly incorrect. The QSV api is used for the media engine on arc GPUs on windows. (see information on the fixed-function encoder here) additionally, QSV is only ever used to access hardware encoding features. If there was no related hardware installed in the system, it would be impossible to use.
EDIT: Arc GPUs are even included on the support table in the QSV wikipedia page you yourself linked.
Ok, you got me, I flubbed that one.
Did not see that QSV is on Intel GPUs.
As I had said previously, I’ve not used Intel GPUs for encoding, and historically, its always been a CPU thing.
However:
https://community.intel.com/t5/Intel-ARC-Graphics/Intel-Driver-Causing-Issue/m-p/1669199#M21274
Go through this and similar reports.
Whole bunch of Intel GPU users reporting problems with QSV AV1 encoding.
Looks like a recent Intel driver update buggered up their QSV AV1 encoding on Arc GPUs, and they are planning a patch to fix it.
Most people are reporting problems with OBS, but it seems like Intel has admitted it’s their problem, hence the incoming driver fix, which would mean that at least right now, Arc cards… do not properly support QSV.
