Mercury Playback CUDA Slower then Software Only Explain?

[wakaf29123949]

Hey guys i recently upgraded my pc for video editing. The 2 Main parts that i got are the Ryzen 9 3950X and the Rtx 2080 Ti 11Gb GDDR6 Asus. I have the latest Adobe Premiere Pro 2020  CC V 14.0.1 Build 71. So from my understanding Mercury Playback Engine Cuda is suppsoed to be better faster then software only but i'm literally getting the opposite. I set it to Software only it's WAAY faster then Cuda. The CPU goes 100% usage when software only as expected and it's great but i think maybe i could even get it faster by setting it to CUDA but i'm getting the opposite and obviously the RTX 2080 Ti is definitely a supported card for CUDA. but it's just really slow + Taskmanager shows the usage at only 1-4% max during Rendering it looks like it's not using CUDA properly so can someone explain how to fix this issue. I'm using latest nvidia drivers as well. Please let me know thanks

You have to be using GPU accelerated effects or be changing resolution to like going from 4k to HD and also Warp Stabilizer. So, it is simply not used all over at the moment. Mostly your GPU will not be called on much. Check this doc for more info:

BTW: 14.01 is not the current version, 14.04 is.

So Mercury CUDA is only for editing effects smoother? It doesn't speed up the render times? Also do i need to install the Studio Driver for the CUDA to work properly because i only have the Game Driver/Graphics Driver not the studio driver i'm talking about this 1 https://www.nvidia.com/Download/driverResults.aspx/156784/en-us. Can you also explain why the GPU only uses 1% when rendering previews it should be way more and in the project settings CUDA is an option meaning it's probably working and in the system compatibility report it shows no errors. My goal is to make render speeds as fast as possible i have a good CPU and a GPU. So which settings should i use for faster Render times? Or set up CUDA to work properly

did you manage to solve the problem? I have the same. ryzen 3800x + 2080 ti. Mercury Playback CUDA slower software ~ 20%. the video card is loaded at ~ 60%, the processor is at 60-90 in CUDA mode. in program mode, the processor is loaded at ~ 94%, the project is processed faster by about 20%. what's the matter?

Pakovalo,

It's your AMD CPU. It doesn't have hardware decoding as Intel processors do. My advice is to transcode any H.264 or HEVC formats immediately. Then your life will be a lot easier.

Thanks,
Kevin

What is ideal PC componant configuration for 6K editing?  Looks like Intel i9 is better for Adobe Premiere Pro than NVidia?  Anyone have a good build list?

[RjL190365]

As of now there is no ideal component, as long as you stay away from the outdated/obsolete and/or very-low-end parts. Beginning with Premiere Pro 14.5, hardware decoding using a discrete GPU is now supported. By default, when you launch Premiere Pro, the discrete GPU is set as both the hardware decoder and the hardware encoder. This lessens the need for Intel QuickSync.

By the way, the integrated Intel UHD Graphics GPU still sucks for rendering. At best it is only about half as performant as even a cheapo Nvidia GeForce GT 1030 when using the Mercury Playback Engine GPU Acceleration mode (OpenCL for Intel, CUDA for Nvidia).

What is best current GPU for Premiere/AE/DaVinci in your opinion?

Was anyone able to find a solution to this? I'm running a 3700x and RTX 2080 and playback at even 1080p is unbearably slow... Running 32gb ram.

[Kevin-Monahan]

eppcMogen,

Sorry. We need way more info on your system and media.

• What troubleshooting steps have you tried?
  • Have you deleted media cache and trashed preferences?
• Is your media on a second internal drive or connected via USB 3 to an external SSD?
  • It should be.
• Is your CPU at Gen7 or greater?
• Are you operating with "Satan in a Wrapper" formats like H.264 or HEVC?
  • If so, have you compensated by transcoding to ProRes or creating ProRes proxies?
  • You should do so since you don't have Intel CPUs which offer hardware decoding for these formats using Quick Sync. Editing any format will be problematic.
  • AMD CPUs do not have Quick Sync or offer hardware decoding for these formats.

Help us out with more info, so we can help.

Thanks,
Kevin

It's a combination of both AMD and Adobe. You see, AMD's non-G Ryzen CPUs and Intel's HEDT CPUs do not have integrated graphics at all, and thus do not support hardware decoding at all. And Adobe currently supports only Intel's QuickSync (which only mainstream Intel CPUs with integrated graphics have) for hardware H.264 or HEVC decoding. Adobe does not currently support hardware decoding through any discrete GPU at all.

So yes, with any AMD CPU or any CPU that requires a discrete GPU just to even function at all, then you're stuck with software-only decoding for the foreseeable future.

Sorry about this.

You will not see a difference unless you apply effects that requires GPU  acceleration
