GPU Acceleration work on certain media?

alifftudm95 wrote on 5/22/2020, 3:16 AM

Here I have 2 different project.

1.The first one is simple project. The video have color grading OFX, music & got a mixtures of 4K 25FPS & 1080p 100FPS media (Shot on Sony a6500 camera).

My GPU is running around 20-40%, sometimes is spike all the way 70%.

 

2. The second project I would say fairly simple as well, just bunch of layer with a mixture of ProRess & HEVC media. All was shot in 4K & 4K DCI 50FPS in 10bit color depth (Shot on ZCAM). All media have Color grading OFX for now, But my GPU is only running below 10%?

 

I have latest GeForce driver, I've switched between Game Ready & Studio Driver & the result still the same. I already make proxy for all media. Im using the latest VEGAS Pro 17 build 421.

AVC and HEVC are GPU accelerated. Not sure about 10-bit, though. I don't think ProRes is.

Your difference has nothing to do with Video acceleration of the Pref/Video, but with decoding with help of the GPU of the Pref/File I/O

Hmm majority of the media was shot in ProPres. But even looping a HEVC media it sill laggy.

Someone in this forum finally manage to run his 10 bit HEVC media (that was shot with ZCAM camera too) run smoothly in VEGAS Pro by just simple switch to Studio Driver. Sadly it doesnt resolve my problem.

I already selected NVIDIA as my hardware decoder in the FILE I/O preference.

I tried a 10bit 4K AVC in vegas. There is no GPU decoding. I then tried it in a media player, there is also no decoding but the media player uses raw GPU instead of the decoder, so with media player 4K 10bit HEVC(gpu decode) and 4K 10bit AVC(no gpu decode) use around the same amount of cpu because both videos are being assisted by GPU in different ways and AVC requires less compute. I then tried both files in Davinci Resolve and the same result as media player CPU is approximately the same when playing both files

Vegas does not use GPU in anyway when playing the 4K 10bit AVC. You did say you were using video proxies so don't understand why this is affecting you. I am using 10 series Nvidia card, new 16/20 series Nvidia may be able to decode. not sure

I also can't playback 4K 10bit HEVC ZCAM footage (with gpu decode) reliably smoothly even though I have plenty of CPU, thought I had to reinstall vegas

I've been testing a new z-cam e2 with my systems using amd and intel gpus with Vegas 17 build 421 and they all decode and edit h.265 footage really well. Even the lowly rx580. I've upgraded to amd Pro drivers on desktop systems but the older Adrenalin drivers work just as well. In fact, Vegas handles the 4k 10-bit 4:2:0 hevc h.265 footage better than it does 1080p 8-bit avc h.264 4:2:2 footage from the Canon xf305 I've used for the last 10 years. Btw, no gpu supports decoding or encoding any flavor of ProRes.

So, you also struggle to play 4K 10bit HEVC media in VEGAS. hmm

I get the slight flickering (black lines) in preview window. cpu 40-50% . Might be some niche setting or something else to fix like using a particular driver. In Davinci Resolve plays real smooth at 22% cpu. Tried dynamic ram preview on 0, but no help. If you do get buttery smooth 4K 10bit HEVC in future make sure to update.
