The ULTIMATE guide to denoising in Blender | Blender Tutorial

Hey everyone!
I have been trialing for the past few weeks the best methods for denoising and this seems to be the best one. I've tried all the add-ons and tried other denoisers but this one seems to make the most sense and best results.
I hope you all enjoy the video and take this into your own projects!

You took Blender's internals and split them surgically. This is amazing, I will try Blender just because of this.

[@BelalAhmed-zg6xr]

I made it ! and now it's in my default startup file and it's waaaaaay better than normal Denoise!! thank you .

[@ethdavis]

Glad to hear it! :)

[@lilpolake123456789]

my startup files doesn't save :/

[@ethdavis]

There will be a mother button after you click save startup file. It’s a bit finicky

[@fullyleaded]

Wow! You should be charging for this wisdom! Thank you sharing❤

[@ethdavis]

Thanks so much!

Thanks you very much for the denoiser 👍

I tried the multilayer denoise in blender, but I noticed that it took like FOREVER to render a single frame compared to a single denoise on the beauty pass. even with the denoise node set to fast, it is still between 1 and 2 sec per pass to denoise! I think I would be better off (timewise) for a similar quality by denoising the beauty pass with just more samples. What do you think? at the end, I just recreated in blender compositor the 3 main passes (final glossy, final diffuse and final transmit), then denoised only those 3... but I am not even sure I gained on quality compared to a simple beauty pass denoise. I think there is a sweet spot in render time vs quality about that. I would love to see a video putting that to the test.

[@iKaGe01]

I wouldn't have even considered multi layer denoising so thank you. I do have one suggestion if you haven't edited the next video yet. Can you increase the audio levels? I was at max on the phone and it was listenable but still had to focus more. Maybe I'm just going deaf.

[@ethdavis]

I can do yeah! Had a few people say that.. It sounds so loud on my end 🫣 thanks for watching :)

[@Jonah_Anthony]

Thank you! I can finally do this without using superimagedenoiser 😄

[@ethdavis]

No worries! Glad it helped 🙌🏻

[@ethdavis]

Thanks dude!

[@fabianogama39]

This was really helpful. I wanted to composite in Fusion, but I don''t have the Studio license yet, I still want to practice before I decide to buy it and the free version doesn't hve a good denoiser for 3D renders (not that I could find anyway). I was thinking of do the compositing in Fusion and then bring back to Blender denoise i, but it would be a dumb workflow. But no, being able to denoise it before in Blender and then go to Fusion solve my problem. Thank you!

[@ethdavis]

No worries! glad it helped :)

thanks Ethan. I loved the explanations

[@drwstr]

Awesome method and great video Ethan :) I am a blender & after effects user and have been for a while. But I learned on Nuke in school, but for my side it soooo expensive. I see that people have already told you about the audio levels. Still a great video tho!

[@ethdavis]

Thanks! Yeah nuke is definitely expensive, I am an avid fusion user before switching so maybe try out that if you want a similar experience? It’s not as good but definitely good for the money! And yeah haha, thanks anything though :)

[@navidumardaraz7163]

How did I miss this?

[@EduardoRamirez-em5qw]

Nice, but on the multipass version you just need to denoise what's needed. Color, emission and environment passes regurlary doesn't need the denoise operation

[@ethdavis]

Thanks Eduardo! Whilst that may be the case for most scenes, you need to take it as a case by case basis. Complex albedos and materials using emission textures will benefit from denoising for sure. Not so environments, but this can help bring everything into the same ball park of noise to add your grain after the fact.

[@timcameron9023]

fantastic

[@ethdavis]

thanks Tim!

[@enhancedsight]

Interesting denoising workflow. I just used a single denoise node and rendered with a higher sample rate if necessary. Will try this out 👍🏻 But is it also the same render time including processing? I thought it takes very long with so many denoise nodes?

[@ethdavis]

It’s definitely better! I’ve noticed a 3 second processing time difference between the two

[@enhancedsight]

@@ethdavis 3 Seconds for 1080p or higher? 3 Seconds doesn't sound that bad.

[@ethdavis]

3 second difference for this Porsche scene at 4k, but I’m using an i914900 and 4090 so not sure if that’s hardware based

[@visuals_live]

Dumb Question…. So this seems amazing but if I don’t use volumes or translucency in a specific project for example, should I exclude those from this process, to save on performance?

[@ethdavis]

Yeah absolutely :)

[@TheDude671]

Hey mate can you show us other two denoising method? please

[@ethdavis]

I've linked the two videos below that explain it really well :)

[@-DarkBlue-]

Based on what you explained, how much do you Rate the addon (Turbo Tools) ? Is it well packaged to do the best denoising ever?

[@ethdavis]

Not worth it imo, better to just do it yourself. It’s the same thing at the end of the day

[@zurasaur]

I’ve been using this method for a while, it does add a ton of render time unfortunately. The compositor is working hard with all the denoisers but it is the best way.

[@ethdavis]

Interesting, I haven't had any different render times on my end. Maybe some crashes but never longer times. Maybe its hardware related?

[@zurasaur]

@@ethdavis I have i9/4090 setup don’t think hardware issue Try rendering the same scene with “use nodes” on and off in the compositor. The compositing stage takes some time since it has to do a lot of extra denoising. The compositing stage doesn’t even happen if use nodes aren’t checked which makes the output much faster. I’m hoping I’m wrong and they’ve improved it, I’m still using 3.6 due to stability/ addon compatibility

[@ethdavis]

Any compositing is going to be slower for sure, but it doesn’t add to the render time. If you compare the nodes without the denoise and with it doesn’t really effect it, maybe 3 seconds if anything? In my test. I’m also using an I9/4090 setup. This is 4.0 so maybe it’s changed? And HOPEFULLY when compositing becomes gpu based it will be rapid? We can only hope hahah

[@fullyleaded]

When you are still in Blender you put all the layer passes through denoise nodes. So they are denoised. But then when you're in Nuke and you do the temporal denoise. Does that mean you're denoising twice?

[@ethdavis]

Nah, in nuke it’s blending the different noise patterns together so it stops the ‘flickering’ if you want to do the temporal denoise in blender, I reccomend watching the other videos I linked. I don’t use it because you can’t do the multi layer components

[@fullyleaded]

Oh I see, so when you output for Nuke you bypass the denoise nodes in Blender? In the Statix VFX video at 8 minutes he says that you can take the mulitpass version and feed it into the temporal average setup but he doesnt show the setup and so its not clear if he bypasses the noise in the multipass...

[@ethdavis]

So essentially when I use Nuke. Everything is Denoised already in blender and I’m using the denoised layers in Nuke. The thing with the temporal denoising in blender, it only denoises the main image. So you lose the ability to rebuild the image back with the main layers. You can add them on top, but nothing else (like change the density of the fog

[@fullyleaded]

Yeah thats what I mean. Everything is denoised already in Blender and then when you take it into Nuke you do a temporal denoise on it. So its denoised a second time? Or am I missing something? Sorry if I'm coming across thick if I am missing something. 🤔

[@ethdavis]

Hahah, no not quite. So what I’m doing is a form of “temporal denoising” which is blending the denoise patterns. I’m using a “vectorframleblend” node inside Nuke which is a bit different, it just blends frames together rather than denoising again. So it keeps all the same detail, just stops the flickering :) if you need any help with something, pop me a dm and I can help ya out

[@2ksp235]

Awesome tutorial thanks. I need help. All my EXR files are completely black. I am using blender 4.0 could you please guys help me? i followed the same settings as shown on this video :(

Hey! How are you trying to preview them? Nuke, fusion, photoshop?

[@2ksp235]

@@ethdavis hey , i am making an animation and i would like to add it to After Effects and when i do render in PNG i have the final render but using EXR, is everything black. Nuke, fusion i fo not have it unfortunately. 🙏🏾

[@ethdavis]

Are you rendering in multi-layer? Sometimes if the software doesn’t know how to read them it may just be reading a layer in there that is completely black. There’s multiple files in a single EXR so that’s probably why. You could do your export as individual EXR files which should solve the issue but I don’t know after effects unfortunately. But definitely use EXR over PNG, so much better

[@2ksp235]

@@ethdavis yeah when it does render i see the image . But when it is saved and let’s say i would like to open the exr file in Blender itself, the image is completely black and it is the same thing in After Effects

[@SeeYouInBluffington]

Great vid, but why did you add the translucency to itself at 7:45?

[@ethdavis]

Direct and indirect are different. You add them and then multiply by the colour to get them to look normal, there’s a blender wiki page about it for a more advanced description 👌🏻

[@SeeYouInBluffington]

@@ethdavis right, but you put the output from one single add node into both inputs of another add node. If I’m seeing this correctly, you multiplied the direct and indirect by the color, then added them together, then added that output to itself

[@ethdavis]

@@SeeYouInBluffington Yeah, so after you multiply the colour, you need to add both passes together.And do that untill you have the final output. If you're curious why, just set up a scene and try it out :)

there is a addon that creates the setup automatically
