VP 17: GPU Decoding Issue

Mohammed_Anis wrote on 8/17/2019, 4:28 PM

In the beginning, I noticed that my my video had a habbit of having some random blackouts during both scrubbing & rendering. I even had some "Low Memory" notices pop out during the process.

To save time, I turned off the GPU, disabled "Hardware Decoding Support" then rendered my clips via QSV so that I don't waste my client's time as I try to troubleshoot this.

After that was done, I came back and re-enabled everything and had a hunch.

It seems that the GPU has a particular limit of sustained decoding time before it begins to bottle neck, somehow. I have NVIDIA's latest Creator Driver enabled by the way. It's a 1080ti. I also have 32 GB RAM and an i7 6770k

Attaching a video here. The video is playing side by side with the Performance Tab on the side. I've allowed it to loop twice.

Please note that the footage is 4K, 50 FPS & from my GH5.

The following is my DXDIAG

And yet, the Studio Driver is also reported to be having a worser performance.from Resolve users.

I'd like to wait for a second opinion on that particular matter before I download it.

With regards to the setting you showed me, as I said: It's enabled. Else, the GPU wouldn't decode the first few seconds of the video (as shown in the video that I attached.)

Nvidia's website states the studio driver is optimized for Vegas 17, so I'd give it a shot.

I don't know what Resolve users know about VP 17 but if that's your opinion and you trust those users more than here on the vegas forum I shall reject my other made comments to your problem.

Thanks, VKMAST.

Yes, but if I've learned anything about what a company says vs user experience, it's what user experience that counts.

Alright. I'll just hold off GPU usage on 4K AVCS for now.

Thank you guys. I appreciate your support.

Resolve Users matter as much as any users of an NLE package, including VP.

The Creator Studio Driver is meant to optimize the experience for Editors, whether they are VP 17, Resolve or Premiere users.

According to the official verdict from the devs here on this forum, they themselves are "reluctant to give it their blessings."

So yes. Their opinion matters. Your opinion matters.

But thank you for your participation.

That will be all :)
