How to increase Premiere export speed while running the app in background?

I'm using Windows 11.

If I export a video using Premiere the exporting speed is good.

However if I put the app in background (e.g. if I open a browser and put it full screen above Premiere) the exporting speed is really LOW.

This is because Windows considers it as a "low priority" task and it slows down the export process significantly. This is so frustrating because I would like to use my PC while exporting. I have an high end system so if I put my browser and Premiere side by side I can use both without lag while exporting, however I would prefer to use a full screen browser/app.

I tried to go on task manager and to increase Premiere Priority to "real time" but it doesn't change anything.

I'm sure this slow down was not happening on Windows 10 or on previous version of Premiere.

Any ideas? How to make Premiere fast on export while running in background?

Thanks

It seems that CoreDirector may be worth checking up! 🙂

"CoreDirector is a free Windows application to keep specified processes from being scheduled to efficient cores (E-cores), thereby keeping them on performant cores (P-cores). This allows improved performance in demanding applications, such as gaming, audio production, video editing, and streaming."

Try it and report back! 🙂

Wow, it works!! Thank you a lot. My CPU is always @ 100% while exporting in background and it also looks a lot faster to export even on foreground.

By the way from the CoreDirector page I can see:

"A common challenge with heterogeneous CPUs like Intel 12th+ generation is the occasional undesirable scheduling of threads onto the efficient (E) cores, hampering their performance. This issue arises because most applications have not been, and may never be, updated to provide explicit instructions to the scheduler regarding their thread load types, leaving Windows to rely on educated guesses."

So Adobe could add a flag on Premiere preferences to allow us to always use P-Core when available. What do you think about this? Should we open a feature request for this? E-Core in future will always be more wide-spread.

Glad that it helped! 🙂

Yes, you should definitely file a feature request for this. Here is a link to that forum: Premiere Pro - Adobe Community

Hmmm... my P and E cores keep humming along nicely, I'm going to have to disagree with that.

I always stick to the Balanced power plan. The two "hi performance" ones, just run your processor the 100% all time. A sure way to say and early good-bye to the processor.

If you go to the DETAILS page of task manager, you can set the priority of various apps there. I've needed to do that, but that's where you set it. Let us know if it helps.

I already set high performance and maximum priority to Premiere on details of Task Manager. It doesn't help.

By @Alberto Bedin

I would start by going to Control Panel > System and Security > Power Options and make sure that you change the power plan from Balanced to either High Performance or Ultimate Performance. When done, restart the computer and try if anything changed.

Thanks, it doesn't help. It's already on High performance (I don't see Ultimate Performance).

Export to h264 1920x1080 using maximus render quality and software encoding VBR 2 pass. However the problem is there also with different settings.

Please note that I don't think it's a bug or a problem related to my hardware/software. Everyone is affected by this. You can try by yourself. Try to export using CPU (softwate encoding) and you will see CPU usage at 100%. Now put Premiere on background. CPU usage goes down to 20-30%.

Premiere's processing is pretty resource intensive. It must have full control of specific computer resources to work at best speed, it cannot share things as the processing code doesn't "split" work off that way.

So no, if you have some resources in use by other processes, it must pause and start, pause and start, as it can only work many of the processes when it has enough cycles of full control of a resource to complete that part of the process.

Everyone's mileage always varies ...
