I was surprised yesterday when a video I composed was much much slow to render than normal - like very slow.
So I check the resource consumption and was surprised to find that my CPU util was under 8%, where its normally maxed out.
The GPU util was also almost non-existent.
After trying various this, I narrowed it down to being the Denoise plugin. When it was enabled, the render was so slow, it would take many hours to complete.
Is my only option to not use denoise?
Please state your Vegas version an build number. Vegas Pro 19-550?
@YodaVonBeck Hi, can you go to your icon at the top of this page - My Profile & fill Signature with your Windows & as John says your Vegas version, + your pc specs, CPU, GPU & RAM thanks,
Just for the sake of sharing, this 0.58sec 3840x2160 clip tales 0.33secs to render using Magix AVC,
With denoise it estimated 20mins+ & maxed out my GPU, temp went up to 65º, I didn't wait - cancelled 😂
PS. the GPU is running at about 44º right now which is about normal

Its Vegas Pro 19, Build 550
Spec of PC is:
AMD Ryzen 5 3600XT 3.8GHz 6/12-Core
Noctua NH-D15 cooler
G.Skill DDR4 PC3600 16GB kit CL16 Ripjaws
MSI MAG B550M MORTAR WIFI
Asus ROG-STRIX-RX5700XT-O8G-GAMING
What I don't understand (but may be normal) is that the render speed reduces with a factor 20 or so.

My GPU was not under any substantial load at all, even though I used the AMD render profile.

My Techno-Philosophical assessment of the Denoise fX is that "it doesn't appear to use any system resource (CPU, GPU Decode, GPU Encode) effectively." If you're over thirty and you're working with media that's larger than SD, you don't have enough actuarial life left to use the Denoise fX.

Thanks, if you go to your icon at the top of this page - My Profile & put that info in Signature i will always show at the bottom of your comments & you won't have to be asked again or people won't have to scroll up to see it,
interesting that neither of your RX GPU's show any activity, my RTX maxes out but is still slow 😂?

Well its 4K files at 60fps, 100mbits and 30min long. I guess life is too short to wait for that to render :D
Lesson learned : Remember to set max ISO on the camera and dont use 60fps in low light conditions

Done :)
Many benefits accrue to those who excel in the acquisition phase of video. Sometimes the schedule slips and we have to shoot video in the dark. I've got noisy video on my hard drives.

@Former user There's been a change in either Nvidia drivers or Windows updates that now causes all Vegas GPU processing to show in 3d window, previously it was spread between 2 engines, 3d and Cuda(hidden engine). Vegas DeNoise showed almost 100% of it's processing in Cuda window. For AMD GPU's it looks like Vegas Denoise is still using a hidden engine. You can tell the GPU is being maxed out by @john_dennis's screen shots, his GPU temperature goes up 20 degrees when using denoise
I predict in the future a lot less people will be complaining about Vegas not using their Nvidia GPU's while the rate of complaints remain the same for AMD GPU users. GPU Processing never changed, it's just more visible with Nvidia GPU's now.

Yup, it is a kernel algorithm, thus the behavior noticed. There is no fast conventional denoise plugin, but Topaz AI is showing promise.
In my experience, Neat Video produces amazing denoise results and it utilizes the GPU very well... I get about 6-7 FPS when heavily denoising 4K video. Denoising is a slow process no matter how you cut it, it's hard for the computer to do, but Neat Video has always produces superior results and speed for me. I've yet to try Topaz, but being that it is based on Topaz' great AI image processing, it probably also produces amazing results, but I cannot speak to its speed.

Had a look at the price......ouch....
$130 for NeatVideo but it works well and is reasonably fast.

Its just more than 3 months income from you Youtube channel, so I think I need to consider other mitigations for low light.
I use a Gopro 10 and did not prepare well enough for the video I shot, but the video was just for myself, so no loss there except feeling a but stupid....
Voukoder (free) also has denoise options at the render stage (add a filter). You can't preview the results, so try on a short section first.
You could also see if anyone with the right tools would volunteer to denoise whatever footage you plan to use in the final project.

I never had much luck with Resolve's motion blur, it always complained about my GPU and still took forever... and the results were nowhere near as good as neat video.

The golden rule is, garbage in, garbage out... you want to make the video look as flawless in-camera as you possibly can. Noise reduction works ok in a pinch, in certain situations, but push it too far, and your video ends up looking washed out, blurry, like a bad snapchat filter trying to hide skin blemishes.

Agree - before I do any more recording low light, I will be testing various settings like, shutterspeed, FPS, ISO and stabelization settings. All contribute to how the camera performs in low light on a GoPro
I progressed from film to graphics to video during my 50 year career.
The go-to solution I use for 99% of what I do is a modest Unsharp Mask at the source.
If it needs more than that, I generally don't bother, except I am learning to use AI denoising in some instances with Upscaling, which itself was a very bad word in my vocabulary five years ago. I don't expect it to go fast.
