Premiere Pro rendering very slow. Not using GPU even though configured to use Hardware Encoding

[Yobik]

Hello Adobe community. I've read through several threads regarding rendering slowness, but swear this is different! 🙂 I have a new computer build that is a monster, and I have run benchmark tests and all are within the acceptable range. I rendered a 15 minute 4K video with the same configuration as I use on an older machine but it's taking 2x to 3x as long, e.g. it's taking over 60 minutes to render. On my older build, Premiere Pro uses the GPU, but on this new build it does not.

Computer build

• Motherboard: ROG Strix X570-E Gaming AMD4 Architecture
• CPU: Ryzen 9 5950x
• GPU: XFX Speedster MERC319 AMD Radeon RX 6700 XT
• Memory: G.SKILL TridentZ RGB Series 4 x 16GB 288-Pin DDR4 SDRAM
• Storage: 2 x WD_BLACK 2TB SN850 SSD (Gen4 PCIe, M.2 2280); one is used for read, and the other for OS and writes
• OS: Windows 10

Notes

• Motherboard and GPU drivers are up-to-date
• Reading 4K .mp4 from drive M: and writing to drive C:
• When rendering, I see barely any disk activity, and barely (if any) GPU activity; however, CPU usage is around 50%
• The Renderer: under Video Rendering and Playback in Project Settings is set to Mercury Playback Engine GPU Acceleration (OpenCL)
• During benchmark tests, GPU shows activity.

Any feedback would be greatly appreciated! If you need more information about the setup / configuration, please let me know and I will provide.

Thanks!

What is "Video Rendering and Playback" set to in the General Project Settings?

[Yobik]

The Renderer: under Video Rendering and Playback in Project Settings is set to Mercury Playback Engine GPU Acceleration (OpenCL)

See under Notes from previous email for other details as well.

Thanks for responding.

you should run a standard benchmark test to compare.

what was your older processor and gpu?

i'm guessing your old cpu had h.264 accelerated decoding build in. it used to be enabled under "Enable Intel H.264 acceleration decoding"

Did your old system have Nvenc or Quick Sync? There is a difference between GPU acceleration and GPU encoding and decoding. The video  below might be helpful.

When you go to Preferences > Media, are the options for H264/H265 hardware accelerated decoding and H264/H265 hardware accelerated encoding available?  If so, are they enabled?

[Yobik]

H264/HEVC hardware accelerated decoding / encoding are both enabled. Thanks for responding!

Have you considered using a CODEC that supports Premiere Pro Smart Rendering?

If you're creating content for YouTube or social media, I would go with Apple ProRes422 LT.  

If you're creating content for broadcast or cable, I would go with Apple ProRes422 HQ.

[Andy 1968]

I render to H.264 for social media. I don't have any issues and Nvenc and Quick Sync can export the H.264 real quick.  The H.264 video codec will create a small file that will be just fine for achiving.

You ever figure this out? I have nearly identical specs with the exception of a 3080 and it is extremely, painfully slow with even the simplest of video editing.

Hi Steven,

Thanks for the note. What kind of footage are you using? Is it 4K H.264? Is it 10-bit 4:2:2? Any additional info would be helpful for solving your case.

Thanks,
Kevin
