When rendering in Premiere Pro, it uses the entire CPU.

Hello Team,

I would like to know why rendering my videos from Premiere Pro uses up all of my CPU usage(100% continuously) My device's speed decreased as a result, and it occasionally crashed.

Hello @RCGAMER,

Thanks for filing the bug report and supplying the system information. That will help a lot. However, the team needs more information about your media and workflow. See: How do I write a bug report?

I hope the community or the team can help you shortly. Sorry for the frustration.

Thanks,
Kevin

Hello @Kevin-Monahan 

I appreciate your reply. I am appreciate it.

Issue - When rendering in Premiere Pro, it uses the entire CPU 100% instead on GPU.

Adobe Premiere Pro version number: 24.5.0 (build57)

Operating system - Windows 11 Pro Version 10.0.22631 Build 22631

System Info:

CPU: Intel Core i9 14900K upto 6.00Ghz
Motherboard: Asus Z790 Maximus Hero
AIO: Asus ROG Ryujin III 360mm AIO
RAM: Corsair 48x2 Dominator Titanium 6600MHz CL32 Black DDR5 96GB*2
GPU: Asus RTX 4090 ROG Strix Gaming OC 24GB
SSD: Corsair 2TB MP700 Core Gen5 M.2 MVMe
SDD2: Samsung 2TB 990 Pro Gen4 M.2 NVMe SSD
PSU: Asus 1200W ROG Thor II Platinum Modular

GPU driver version: 555.99 released on June 4, 2024

Video format: I have added the SS for reference
Workflow details: just basic for now editing gaming videos
Steps to reproduce - just basic thing not much high end
Expected result - why it goes CPU to 100% as its totally depends on GPU for rendering.
Actual result - while starting export it will constantly 100% usage of CPU.

Very obvious, actually. You chose to use 2 pass H.264  encoding and no GPU is ever used for 2-pass long-GOP encoding. Period.

Use a single pass H.264, and where there are GPU accelerated effects involved  such as color or resizing, the GPU will get used.

That isn't an Adobe choice or under their control. It's "the rule" in video file encoding processing.

We're frequently getting people, uh, er... 'inquiring' about not using 100% on their systems. So, interesting to see it. And excellent spot by Neil. 🙂

It's normally Ann or Michael or someone who catches that one!

Hello @R Neil Haugen 

I appreciate your response. 

Can you please help me with the best way to export the video. Its a bad headache for me. After that it start my PC crashing occasionally. So if anyone who can help me with the best settings to export or any articles much appreciated. Thank you once again for your help😀.

A bit about H.264/long-GOP exports ...

You can select either 1-pass or 2-pass exports. There is a huge effect on processing depending on that choice.

Because all 2-pass encoding must be done by the CPU in total. This process cannot use the GPU on any hardware or software. It's "the rules" set by the people what makes the process.

2-pass encoding will be a LOT slower on most machines!

Another choice is VBR versus CBR ... variable bitrate versus constant bitrate.

VBR encoding means there is a range of data total amounts per frame that will be accepted ... so that when there's a lot of fine detail, more data is created, when there's very little fine detail, a lot less data will be created.

CBR encoding means that no matter the detail level of the image, there will be X amount of detail written to file for that frame. 

In reality, though CBR sounds better, VBR is by far the better choice for most things as you can set the min/max settings to your needs, and not 'waste' data space on stuff that doesn't need as high a data rate.

So unless you really do have specific needs, like ... a service sends a pdf for deliverables that you must abide by ... 1-pass VBR set to a tested, adequate level in final use ... is probably the better choice for nearly all workflows.

But as with anything, TEST!!!!!!! 

If you send to Youtube ... produce a short sequence with a range of images. Do a couple different settings for export data rates, and upload. WAIT 24 hours, to make sure that YouTube has finished their re-encoding process.

Now ... view that on several devices, preferably on both PC and Mac. A TV also.

You'll have the answers you probably need.

I'm grateful for the information. However, I verified this with my PC builder, and it appears that there is a hardware or CPU core issue. But fear not—as soon as I have my PC back, I'll attempt to check. Once again, I sincerely appreciate your assistance😊.

Hi @Rutvick37025740gmbk,

I'm glad you were able to nail down a potential source of your bug. Have you received your PC back from your builder and are you clear of this issue yet? Please let us know. I'll move this report into the Discussions forum while we await your response. I apologize for the issue.

Thanks,
Kevin
