Reducing render times by 92%! Denoiser showdown
HTML-код
- Опубликовано: 28 сен 2024
- Blender tutorial showing you how denoisers like Nvidia's Optix can reduce your rendertimes.
EDIT: Since recording, Blender 2.9 was released with denoising included in the default installation (no need to install anything extra), and it supports all hardware! Find it in Render Panel: Sampling: Denoising. Optix (faster) is for compatible Nvidia cards only and OpenImageDenoise (slower) works with any CPU.

Since the recording Blender 2.9 was released with the denoising shown in this video included in the default installation (no need to install anything extra), and it supports all hardware! Find it in Render Panel: Sampling: Denoising. Optix (faster) is for compatible Nvidia cards only and OpenImageDenoise (slower) works with any CPU. Have fun ;)
Any news in the denoising for archwiz aniimation department? :)
Thanks, appreciate the update!
does it work on gtx cards????????????????????????????????????
@@blackknight47 Works with my GTX 1060, so I guess it works on gtx cards!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
is there any AI denoiser compatible with AMD ?
Since recording this video, some big news was announced:
1. Optix Denoiser might actually make it's way into Blender officially, removing the need for an addon. (nice!)
2. Intel's Denoiser (not shown in this video) will be included in Blender 2.81! Early results look very promising: twitter.com/BlenderBrit/status/1164306780089978881
😍
ODIN is actually already in master.
I have an all AMD build :/
@@nerdroberts1927 Intel's denoiser works with AMD, any CPU that supports SSE4.2
Why wait? It's available already.
4:09 Andrew with Blender Denoiser
4:11 Andrew with Optix Denoiser
He over used the denoiser on himself
Hahahahahaha
lol
lol..instant haircut. He even wearing the same shirt.
when i saw that andrew change i go down to read comments and i find this first comment. hahahahhahaha
After denoising, don't forget the filmgrain.
nice nice
Sounds goofy... But I regularly do denoising on video (with Neat)... And then I add just a tad of film grain. :D
In short... While technically grain is basically the noise equivalent in film, there is a big difference between how film grain appears vs video noise. And it does have the perk that it dithers what otherwise could end up as color banding.
This aint a joke. Dithering. Look it up. Makes the scene look more photorealistic. Within reason of course, nobody's advocating the 8mm look
@@jmalmsten Interesting! I want to try it out. Off to go check out Neat.
in after effects anywhere betwen 2 to 5 % grain is a good amount , it already dithers but doesnt deteriorate
Someday it'll be nice to get back to Cycles, but for now, I'm loving the 2-6 second render times with EEVEE.
Eevee is so much non-realistic with horrible shadow and low quality material
@Blank Person what, the ram dosn't change anything, i have 8gb of ram too, you need, a nice gpu, or a Nice Cpu, i reccomend you a nice gpu, if you want to gaming too... also the gpu i have render in Cycles in 4 seconds a really big scene, instead the viewport it renders istantly, my gpu is only 170$ Gygabyte Nvidia GeForceGTX 1650 super
@@blk9365 stupidest shit ive heard ever ram does matter for 3d anything 16gb minimal, its neccessary for a few reasons mainly for rendering mid to high poly scenes i myself have 64gb which allows me to load in up to 128 billion polygons granted that isnt really neccessary for small animations but for larger ones its neccessary
@@andrexsintoval3776
Now we were talking about rendering time, the most important thing is the Graphics card
@@blk9365 yeah but if your gonna be using mid to high poly assets its important to have the ram to do so
Blender 2.81 will have INTEL's denoiser. It's supposed to be better than Optix.
I've been testing the intel denoiser myself and I'd say it's on par with Optix, not convinced it's better though. The downsides of Optix certainly appear to be present in Intel's one in a like for like situation. The best difference is that the Intel Denoiser is implemented as a compositing node allowing you to work some node magic to preserve details and, of course, it's open source so way more Blender friendly.
@@BlenderBrit Sorry I forgot to clarify that it's better for edges, as it uses the normals in the denoising as well.
at first I thought Andrew is talking about that
yes, I assumed he was going to be talking about it in this video but apparently not, lol
So no AMD denoiser? I suppose it's only gonna work on intel CPUs... oh well neat video still seems like a good option
5:11 your hear grew considerably through that little transition there.
How is nobody here freaking out at how he says Nvidia? Neh-vidia? What madness is this?
Nowhere near as bad as mrwhostheboss and his Fuchsia pronunciation.
That’s how I would say it...How would u guys say it?
Patrick Edwards It's actually pronounced "envidiah"
En-vi-di-a
I was actually shocked too. I have never heard someone saying it this way. From all the beginning i have always pronounced it as "Envidia"
I'm not even an animator or artist, I have never used Blender in my life. But I seem to always watch videos of yours that I come across. You do a great job at making me interested in changing career paths into this industry.
Andrew why don´t you mention two of the most important options in Blender?
- Open Image Denoiser: already in master for 2.81, available for months in the Theory Studios build and our own build, Bone-Studio, in graphical.org
- Temporal aware blender denoise, already present in 2.80
Both are way better than the options you present here IMO
Honestly I recorded this a good 6 weeks ago, and I couldn't find any way to make Intel's denoiser work.
@@blenderguru Use our build, it's available in graphicall, in fact tonight (in a few hours in spain) I'll present a new feature that will be implemented in 2.81 or 2.82, but we just implemented it in our branch, stay tuned to our channel, the live will be in english :)
@@qozia1370 calm down, son.
Could you link me to a good temporal aware blender denoise video, article or something? I have never heard about it and in a quick search I couldn't find anything
@@GCAF_ Have you find something about that topic?
+1 for Neat Video plugin. This plugin is simply the best on the market right now. We were able to render 12+ animations via Octane, and with the samples down to as low as 1500 in some shots.
Then a quick denoise, and it was like we had rendered at 25k.
No one:
Andrew: _NEH VIDIA_
Saw your AI vid yonks ago and am still drooling ... have used Neat since for-ever for my astrophotography ... I'm fully invested in your superb channel and love your passion for Blender (which I downloaded way back in late 2001... maybe 2002(?) and struggled with until about 5 yrs ago... as a part time hobbyist only). Imagine my genuine surprise to hear I've been incorrectly pronouncing my gpu as "EN-vidia" rather than, as I can now appreciate, should be referred to as "NAH-vidia". Cheers, guru... much love :)
Mid video haircut at 4:10 :D
Yup. Only one month apart too :P
It was left on the "cutting room floor". :D
As someone else mentioned, it's due to the difference in denoisers.
@@blenderguru I thought you went to exercise and then took a shower there in the cut
What's amazing is that you can use the denoise node in the compositor not just for 3d renders but for 2D Real Life Images too! :O
Everytime you say "neh-vidia" an angel loses their wings.
My buddy would call it Ni-vin-dia . Never understood where he saw the second N.
@@LetTheWritersWrite Hahaha! Hell, if you're gonna say it wrong then you might as well go all out.
why
In case you are as lost as I me: The integrated denoising feature in Blender 2.9+ is actually located in the tab called "View layer properties", at the very end, and not in the "Render properties" tab.
1:31 "Na-vidia"
HOLD ME BACK BEFORE I SLAP THIS BOY
He's Australian. He's saying it like that just to piss you off.
Obviously the proper spelling is "novideo"
i say it like that
About the standard denoiser: I found that the "blotchy patches" you speak of are usually more pronounced when using "randomize grain", which in fact should be turned off when using the standard denoiser.
Please start a new tutorial series using blender 2.8. I'm struggling with ui in the donut tutorial.
Hunan beings are basically just a walking doughnut
yeah i was waiting for an update like this to learn blender
There are plenty of excellent beginner tutorials on YT already, I can recommend Grant Abbitt, he's made some great videos for 2.8 beginners.
Impressive the special effect at 4:11 🤪. Very instructive as usual
And just as this came out 2.81 for Intel open image AI denoising
Yep. Great timing :P
I actually recorded this 6 weeks ago, and when I looked there was no easy way to test the intel denoiser back then. I'll eagerly await 2.81 to do a comparison :)
Blender Guru have you tried the bone studio Blender build in GraphicAll, comes with the denoiser as well as adaptive sampling which i think you will love, it decreases render times a lot in some scenes
perfect timed haircut change while explaining what denoising is
I prefer remove denoise in the pos-production, you change your pass layer with noise e apply denoise pass by pass, its keep more information, BUT it is very cool, thanks for this information :D
You didn't mention the new Blender 2.81 INTEL's denoiser node.
How well does that work with animation?
Much more stable but still not fully there.
will it work for animation? or still frames only?
4:08 Andrew’s hair is so magical
wow im impressed how on earth did you get a sponsor with polygon? Thats amazing!!!!
Thanks so much Andrew i used almost three days to render single animation with duration of 13 seconds for my RUclips channel, this trick is all i wanted. Can't wait to use them for my next videos.
5:33 Most impressive paranormal moments caught on camera
Thanks for featuring D-NOISE, Andrew!
Optix temporal denoise since Blender 3.1 is amazing for animations, more people should be talking about it!
No one seems to have tested it because there is no documentation. I got this far:
Set render output to EXR_Multilayer; turn on vector and denoise_data layers and render an animation. Then open up python console and enter:
bpy.ops.cycles.denoise_animation()
It goes through each saved image file for each frame (so its best to test with just a few frames), and overwrites the layer "View Layer.Combined.RGB" with a denoised version.
(I think you have to have an RTX card, Optix as the Cycles Renderer in System settings, and turn denoise on in render tab, select Optix, then turn off again - I don't know if all this is necessary, but when I initially tried with Cuda selected in system settings, and OpenImageDenoise in render tab, bpy.ops.cycles.denoise_animation() worked, but the results were poor. So I did everything I could to ensure Optix was being used, not any other denoiser, and got much better results.
Open the EXR image sequence in Davinci Resolve, go to Fusion page, and on the MediaIn node, choose the layer RenderLayer.Combined.
You got me stumbled with your pronounciation of nVidia. It's Enn-Vidia, not Navidia.
It's Leviosa, not Laevioeesaaa
Yes, i agree
Maybe worth noting - Neat Video is GPU accelerated via both nVidia and AMD cards and renders extremely fast.
2:16 Click "Install OptiX Binaries" won't install What to do???
me too
lol , it's old mehod , now it's integrated inside blender , no need to install anymore.
Man, now that is awesome.
How the hell YOUR company can sponsor YOU? :P
Great tutorial video BTW ;)
business expense loophole :)
He should rephrase that to "is made possible" or something different..
@@Slickstaff_Stainpants When you want to promote your own company so you sponsor yourself by it :P
@@SuperBialyWilk :) heh, i see no problem with it. Its not like its a secret.
There are different ways to advertise.
Guru, please do a video explaining different roles in the industry, and their responsibilities. For example, what is 3D generalist, Technical artist, etc. As someone who is interested in entering this field I would love to get some insight and focus on how stuff works. Keep up the Amazing work you do. Thanks for everything!!
Was waiting for this video!
Thanks! - That's a really great look at denoising - it's good to hear the ups and downs (so much of AI raytracing tech is sales talk these days). Also good to hear the comparisons you've mentioned - it'll be fascinating to see how this all settles in few years (to think I used to ray trace on workstations 20+ years ago and we'd wait the night a basic image... ! )
There are a few videos in RUclips that are really diamond for me. And this is one of them. Thabk you so much
Can confirm that Neat Video is incredible. Worth every penny!
Nuh-vidia? NUH-VIDIA?
First of all, congrats on the sponsorship. I haven't been keeping the tightest track on your channel, so for all I know you could have had one for months, but good to see you moving up the chain all the same.
So I downloaded D-Noise a few months ago, but I never used it because my friend kept tell me, "just check it and go. You don't need anything else." Needless to say, it didn't work, and I've since learned that if there is a Download button attached in the user preferences, it's usually a good idea to click it. But like you mentioned, it does smudge out edges, which is something I never liked. But, better then nothing.
So what sample range do you generally work at? Obviously each project is general, but as a general rule of thumb. Everyone I've talked to insists that it's a different number, and that their number is the universal standard (Those being from 30 Samples to 1,000+). Currently I have 256 as my default, but I'm not sure if I should bump it up to 500 again, or would that be diminishing returns. I like to go more photo realistic, but I'm definitely not near the point of the kitchen in this video. :P
Uhh ... Poliigon is Andrews company. He is founder and CEO. So when he says "sponsored by .. " he is sponsoring himself. Nice tax right-off though.
@@kotronics_arts Wait, wha? So what is he just handing himself money in a mirror?
@@BrownFoxWarrior Yep ...pure genius ... good business ...
is it just me or is hitting a huge button in blender really satisfying?
I know this vid is 3 years old, but I found out that for far away physics based animation, that 1 MIL start sample on albedo and normal passes on optiX, then for the advanced you want 1 mil for the sample offest, then 32 max samples for rendering, it works well in my case
Just in case somebody isn't aware of it, RUclips has a 2x speed function, meaning you'll have to spend just half as much time watching any video. It's especially useful for videos where people speak very slowly
I think that the noise which especally is in the shadows while animation, adds more realism. Its like a real camera. Just rec something in dark areas, and you will notice the noise. I would say, that noise is not always bad, especally when it comes to relism. And you should know, that realism is not perfection, its the opposite: ITS IMPERFECTION. Awesome video.
Hey Andrew, I don't know if you already knew this but for emission objects (I mean not blender lamps but solid objects) there is a node called light falloff that can be connected to the strength of the light. It reduces the strength by providing that the light strength doesn't reach an infinite value (quite common in blender cause of noise). It reduce much much the noise. If you didn't know I suggest you to try it, it changed my life 😅. Let me now if this was helpful
I appreciate all the work you do for the side by sides. You don't get enough credit for that sometimes. Thanks for the info, especially on glass, the white pixel fly aways drive me nuts, so I'm looking forward to these possible solutions.
Used altus denoiser, found it working quite good. The bad thing is you have to pay for using it without having the watermark.
Am I really the only one wondering about his pronunciation of Nvidia?
I mean, "nahvidia"? What?!?
Isn't it pronounced "N - vidia"?
Kinda like "envy" - dia.?
Other than that, interesting video.
I believe I saw a video mentioning that 2.81 will get an Intel made denoiser. Be fun to see another comparison then.
No, you're not the only one, and you're right, the correct pronunciation is "en-vidia"
Blender Guru: modeling artist and mathematician
"this video is sponsored by poliigon!"
but... don't you own Poliigon?
I mean. he already has a huge following. It's basically free advertisement. and the service offered is really good.
*THAT'S THE JOKE*
Hey, I just wanted to say that I've never loved another man before, so this is all new to me, but your entire channel is just making me feel very different feelings about you.
He has a wife you know. /s (Monty Python)
nevidia? it's pronounced as en-vidia....dude, lol! Living under a rock, have you?
Thanks for the comparison Andrew.
*Tells me that the flickering will be very noticeable*
*Continues to put a giant arrow pointing at all the flickering*
*Completely ignored the part where YT compression was mentioned* 😜
I've recently bought a blackmagicdesign camera and got the full version of DaVinci Resolve for free. I found the denoiser in there to work amazingly good with very little hardware requirements. I'm running on an i5-4670 and R9 390 and footage stills plays smoothly
Oh, I am very excited for your tutorial video to be uploaded. I can't wait... Please upload it ASAP. ..
E cycles addon has also an ai denoiser. In my opinion its very good and powerful.
Now, I do all my animations inside blender 2.81 with the new amazing Denoiser! It's a huge update!
i feel the powerful power in here
I predict in the future a lot of our workflow and modeling will probably be just setting landmark objects, and giving each object metadata tags for an AI renderer. The 3D interface will most likely only be needed to assist in setting a temporospacial tag for each object and separating them via color for our eyes.
The AI renderer will have a generalized architecture, probably generative adversarial, and have a separate word-association layer for us humans to interface with its settings. Datapacks will be downloadable that have been trained on specific images that can set color grading and textural effects. Multiple datapacks will probably use image masking to give only specific objects neurostyle textures and materials.
Vray has a standalone denoiser that works very well with animation frames. Really consistent and you might be able to use it to post-denoise your frames from Blender.
I came back to this tutorial beeing sure that you used the Topaz AI Video app. And it turnes out it's actually Neat Video. So, I was thinking, since a lot has happened in this industry recently (AI), maybe it would be a good idea to take another go at this? The Topaz software I mentioned is not only a denoiser but also a pretty remarkable upscaler and can also do frame generation. I did some tests a turning a 1080p 24fps noisy render to a 4K 60fps noise-free render. And the results are pretty crazy.
you can reduce noise by adding a denoiseing in compoisting menu
you can get the same nvidia gtx denoise
With cycles, denoise, and an RTX 2060, i finally have awesome renders, even glass comes out beautiful
@Blender Guru Octane's denoiser (V4 and newer) is actually pretty incredible and works with animations (temporally stable) to my knowledge as well. It's also completely free for Blender with it being limited to single GPU rendering only.
Andrew, could you please do a series on shaders? And then do a series on step by step instructions of how to use blender, lighting and UVS?? If I have to I’ll pay you, I just cant seem to get those subjects down
Radeon Pro Render from AMD (it works on any GPU or CPU) comes with a couple of different denoisers, including an AI based on that seems pretty similar to Optix. Pro Render replaces the Cycles renderer with it's own renderer as well though, which some people might not like, even though it does seem to be quite a bit faster than cycles.
Nice video! I can recommend Davinci Resolve Studio built in denoiser! It is fast and fantastic. Also Davinci Resolve performance scales with the amount of GPUs you have in your system.
Your videos are so helpful! You got me started and I still learn so much from you. Thanks!
Hm, I used denoizer, and after that de-flicker plugin in Natron, to remove flickering effects.
This is really fantastic! Definitely downloading!
Awesome!
I remember watching this a while back. Such a thorough review of the denoisers. Thanks so much again Andrew. So 3 years later, what do you all think is considered the better denoisers on the market (or even photo enhancers)...especially with all the ongoing A.I technology that is out? There are so many A.I. apps on mobile too. Are there any updated videos out regarding A.i. enhancing topic such as this (not the A.I. art generating topics *yuck*). Would love to find a comparison between Blender, Optix, Topazlab, Intel, etc. 3 years later.
@BlenderGuru
Pixar's Renderman has crossframe denoising available since forever and it does a great job at denoising animations. Also, anyone can test it and start using the non-commercial version. It's commonly used in VFX. rmanwiki.pixar.com/display/REN22/Denoise
While "noise" and "grain" tend to be used interchangeably. They are teo distinct different things. Only film has grain. It comes from physical inconsistencies of the materials of the film. Noise comes from the digital world only.
My idea that I don't have the resources to make come true, an AI that works like video compression on rendering, meaning if one bit of the image is still the same as the previous frame it won't render again, to speed up render time, no more rendering a sample that is only dark square's repetitively and wasting time
Awesome stuff Andrew!
i just got back to 3d and this is great content for me. Thank you so much.
coco and frozen 1 is use in Pixar Renderman
Thank you so much. Video like this was needed for the tech review (Frozen, Moana). Yes, Neat Video is a king classic tool!
wow. thanks dude this helps me a lot
bro ur my hero
Davinci Resolve has a denoiser only available on the studio version. It works well sometimes, but I haven't played with it too much to make an opinion.
Just discovered from the author that it is not compatible on Win 7- The Optix. If you find that the D-noise freezes on 2.8, it's because of that win 7 issue. I have also learned the fix, while impractical. IS to kill the denoiser.exe in the Windows task manager, then suddenly you will see the result in blender. Impractical? Yes, Effective? Definitely.
Friend i sees your this video without an skeep and i well use your given tips after an hour. I well mention you what i get benifit with this video.
Maybe we can combine Cycles and Eevee together. Which means we can select low-noise layers of Eevee rendering and realistic layers of Cycles rendering, then combine then together. Maybe it could be a good denoise technique.
Neat Video has saved several projects of mine.
FRIGGIN AMAZING! How did i miss this?
Very cool. I had no idea.
Arnold renderer is quiet intuitive when it comes to eliminate noise. I just wish I had a better pc that didnt take soooo long to render. Now after school i dont even have access to their super computers. Everything takes much longer now. Even seemingly small things like opening scenes or playblast renders.
I enjoy looking back and see what we had to deal with 5 years ago though. Both Blender and Maya have come increadibly far.
Thx moviemaker a real powerful VFX handy-creativ Effektgenerator
I don t know if the denoiser wich comes with e-cycles is intel but it s the best imo after test it keeps more détails and flat surfaces are cleaned and you can adust the blend in the compositer
The flickering in the shadows of the animation example reminds me of the total solar eclipse in 2017. I was just outside the totality, maybe 20 miles. Outdoors. As everything got dim, I noticed ripples in the shadows. So maybe improper application of a denoiser is a trick to product that effect in animations?
Andrew, we need the new donut tutorial! I heard in a video you are making a new one for 2.8!
Thank you there !!!!
RUclips compression is a pretty good denoiser too.
So no one noticed Andrew sponsored himself in the video as he was the founder of poliigon.
