Make sure to uncheck "Random noise pattern" under the tab "Unified sampling" when using denoiser otherwise you might have a splotchy effect due to the noise pattern changing at every frame. That's what you want when not using denoiser to mimic real camera film, but when using denoiser it's counter productive.
PERFECT! Thanks for sharing your results. That's what we expect from Render Optimization... faster times, minimal changes in quality. Thanks for watching. Now try adjusting the Global Trace Depths. Sometimes you can get away with reducing the rays. Render Settings > Global tab > Trace Depths
Incredible video. What I have been doing lately is rendering in 1920x1080, turning off the denoiser, setting progressive passes low and sampling threshold to like 0.1 or 0.2. I then go into Topaz Video AI and upscale and denoise. Sometimes the results aren't the best but since I often take this into After Effects and have to do a lot of compositing anyway, the details often aren't being seen.
Thank you. For longer sequence I use Neet Video plugin that does a fantastic job of denoising. For my product shots I can get away with pretty noisy renders. Topaz is amazing too! I try and avoid plugins on this channel so I've not talked about them.
Great tips. I suggest also setting bucket size to zero on denoising. Doing that alone has cut some of my renders in half or a third without any major difference in render quality.
This video has got lots of suggestions which has inspired to make a more comprehensive video on render settings. I didn't want to get too detailed in this short video. Thanks for the suggestion!
My god. lol I had a proj with a big glass refractive/reflective logo for a comic book company that shall remain nameless. Anyway, my frames went from 11 min per frame to a minute and a half. Practically identical. Insane. I just watched a bunch of your vids. You're badass, dude. Thank you.
People have gotten irritated that I didn't go into detail, so I plan to do a proper scene optimization video. Glad you got good results! Thanks for sharing!
Love this, I have used the built in denoiser and also tried denoising after and I 100% recommend doing it after the fact. the built in denoiser destroys a lot of the detail and adds to some weird warping.
Denoisers are contextual and circumstantial especially for client work. I've avoided covering them in videos because of this. The results vary drastically between projects.
Great video. Taking down some of the trace depths will help speed it up even more. Transparency trace depth kills render times and can often be brought right down, depending on your scene. Same with reflection depth.
YESSSS! Fantastic. I suggest you make sure you're using the correct Denoiser. One that doesn't remove too much detail while keeping your times down. It's a balancing act of compromise. Thanks for the feedback!
These are some good tips, but the optix Denoise workflow is definitely not suitable for final renders. It’s great for getting a quick clean look but in my experience any scene that has a lot of high frequency detail will come out looking mushy and soft.
I agree. This wasn't a denoising video and I'll cover it in more details in another video. I've got an entire denoiser video I'm writing. Optix looses plenty of details. I completely agree.
In this case brute force is faster, because of the hair (a lot of tiny uneven details) so the IRC have hard time optimizing it. When you would turn fur off, you would see the suggestion fail. When talking about animation you probably want to avoid any denoisers (for fast preview renders yes, good option). Denoisers will start to kill your tiny details also.
Videos on rendering are tricky due to all the variables! As far as denoisers you simply need to do a cost/time/quality evaluation with client work. Not all the time do you have the resources to use the best denoisers. This video was just an overview primer with many details left out. Thanks for your input and watch.
I don't get any flickering. If you do get flicker, turn it off and do a quick render. It might be your Global Illumination. Change them both to Brute Force, default is Irradiance Point Cloud which can flicker.
RS is quite powerful, yet it's not sufficiently intelligent to rely on automatic sampling. I've encountered numerous instances where manual sampling is significantly quicker. So, keep in mind we still have some room to shave off even more.
Of course thank for the feedback. Manual vs Automatic definitely deserves its own video. Render optimization is such a huge topic! You gave me another idea. Thank you.
The thing with manual sampling is that depending on how complex the scene is, you can easily end up spending hours in setting up the samples...and those hours can just be the same as those saved for your computer to render. I wish RS had a simpler sampling system same as Arnold does.

Dude I had a 16 minute render that came down to 3 minutes each. Looks literally exactly the same. Thankyou so much

Exactly, this was just a primer/high-level video. Trace depth optimization is a key point for sure!
very useful video thank you
brilliant! really good tips
Thanks for watching!
Can't wait to try this on my next project
It will surprise you! Comment your results!
Thank you, it is clear.
You are welcome! I upgraded my mic rig so things are sounding better and will continue to improve. Stay tuned... more to come!
Was cool to see this thanks !
Do you have discord ?
I'll be setting up Discord for the channel once I hit 100 subs. Almost there!
Awesome tutorial! I did your methods and reduced my render from 32s per frame to 6s per frame with little to no change in render quality!😀

Goddamn, SUPER useful! Love it, Homeboy! X
Quality video, quality channel 👏

Thanks man
You're welcome!
Great tutorial! project file please
Many of my videos provide a project file when appropriate. Is there something specific in this animation you'd like me to show you in a video?
Very useful
Does the denoiser also work with animation? I thought it will produce some flickering
I don't get any flickering. If you do get flicker, turn it off and do a quick render. It might be your Global Illumination. Change them both to Brute Force, default is Irradiance Point Cloud which can flicker.
