Handbrake slows down while encoding of AV1 using Intel Arc a380

[compapps7500]

Problem Description

When encoding using AV1 10bit Intel QSV it starts encoding at 200+ fps, but in a few moments it goes down to about 30 fps.

It is usually encoding quickly for about 15 seconds or so before slowing down.

I have noticed this behavior in HEVC 10bit Intel QSV encoding as well, but do not know what is causing this issue. In Task Manager you are able to see high gpu usage at the start of a file encoding until it drops down to about 10%.

What Operating System are you running?

Windows 10

What version of HandBrake are you running?

1.7.1

Where did you download HandBrake from?

handbrake.fr

[sr55]

The start of an encode is often much faster because the frames are often very simple. It takes a minute or two for things to settle down.

Your running an ARC card on a system that I suspect doesn't support rebarr and is also using older PCI-E slots that won't be full bandwidth with dual cards. so it's going to kneecap performance.

It may or may not help, but you could try the ARC card in the primary PCI-E slot without the AMD card installed to see if it makes any difference but overall, your settings are good and there are no errors indicated in the log.

[compapps7500]

I found a way for it to go at full speed sometimes. If I change the setting to have two encodes happening at the same time then the first encode will happen as the log says above, but the second encode to start will use the rest of the GPU's resources as long as the first encode is still processing. If the first one ends then the second one slows down.
I got the log of an encode that is running quickly as I am describing above:

[23:38:17] hb_init: startin

This log and the log from the first post came from the same system configuration and without any reboot between them. I don't understand this behavior or how to make sure I get the full speed all the time because running two encodes at the same time does not always seem to give me full utilization of the a380 everytime.

[melsoftm]

The a380 might be going into low power mode, you might have to change some bios settings to prevent this. Or there is a bug somewhere causing it to kick into low power mode, if you can connect a monitor to force it to play a media file through the card and encode speeds shoot up its either a driver bug or a program bug.

*removed edit was a deprecated power management model

[chorong761]

Try Audio Passthrough instead of encoding it
