Intel iGPU behaving strangely in Premiere Pro 2025

Report · Oct 25, 2024

Strange things are going on with my i7 14700K's iGPU in Premiere Pro version 25.

First of all, I've worked in Premiere Pro for ages and I'm used to monitoring my system resources via the Task manager in Windows. There are all kinds of graphs there that can be switched on:

I know that the Video Decode graph shows the iGPU decoding process whereas, as Intel says here, Video Decode 1 shows the encoding despite the name.

It's been so for years and it was convenient.

But now - for some reason these graphs show not what they used to.

When I decode, I see this:

Yes, during decoding my iGPU encodes something which is nonsense. And yes I have nothing being encoded in the background. So either it's a bug somewhere or my CPU lives its own life.

And when I encode, I see this:

3d graph is filled up to 100% (what does 3D graph even mean if there's nothing 3D in my videos), Video Decode has a short spike desite there's nothing being decoded at that moment, and Video Decode 1 which is essentially the encode graph is empty.

Someone please explain.

PS: Microsoft and Intel were sent the same info and questions.

Hi @AndrewTheGreat - I see you are having a lot of issues with Premiere Pro and I would like to try and help fix it with you. Thank you for taking the time to troubleshoot and try a bunch of suggestions. These are some very unusual problems you are experiencing especially with your iGPU. You mention that you have contacted microsoft have they written anything back you you?

I see from this Post that you have made some modifications with your GPU and iGPU I haven't seen anyone do this before. Do you still have this as your setup?

Hi again, @jamieclarke

Those were not my modifications, I pointed that out:

I don't have an addition HDMI cord and there's only one hdmi connection on my monitor, so I cannot use it. Besides this issue is the one the programmers should fix, not the users.

As for the encode and decode graphs in Windows mentioned here, in this topic, yes I emailed Intel, they responded and asked me for a lot of additional info and a screen recording. I sent them all and since then they've kept silent. Hopefully they are investigating the issue. I think Adobe should do the same on their part. I will cooperate if needed.

Hi @AndrewTheGreat - That is interesting that intel wanted a screen capture and is investigating.

There are two workflows in your post, the first you state "my collegues and I have found a strange work around for how to still have the iGPU on and the thumbnails generating fast. You have to insert a dummy into the motherboard hdmi port, the dummy being an hdmi-monitor emulator KS-554, like this one:"

and the second being "The workaround is to connect your monitor to your integrated videocard while it's already been connected to your videocard."

Thank you for confirming that the second case was only your colleague. Is the first case the same? Thank you for taking the time I'm just trying to gather more information to be able to narrow down a possible cause of your issues.
