Innobright's Altus uses a traditional and production-proven techniques to achieve its denoising effect. On the other hand, NVidia's OptiX AI denoiser uses a deep learning algorithm that has been trained with tens of thousands of images.

Innobright's Altus is a commercial product that has to be purchased separately, although Redshift users can benefit from a special offer specifically for them. For more info on this, please follow this link: https://www.innobright.com/redshift/

NVidia's OptiX AI denoiser is free.

Each of these two denoising solution has pros and cons:

...

(plus) Uses production-proven algorithms so results can be more predictable(plus) Altus sells a separate "ServerPro" version of their product would can denoise across animations

(minus) Denoising takes several seconds to compute so it's not possible to use in an interactive fashion

...

The Altus denoiser options can be found in Redshift's Output tab.

To enable denoising with Altus simply select "Altus Single Pass" or "Altus Dual Pass" for the denoise engine and then do bucket rendering (Altus does not work in progressive!) using the Render View.

After the frame has rendered and OptiX has denoised it, you can toggle it on or off (to better see its effect) in the Render View by pressing the  button of the Render View.

Animation Considerations

Warning

When rendering an animation, we recommend disabling Redshift's "Randomize Pattern on Each Frame"!

Doing so will make the noise effect be "stuck on the camera" instead of "dancing around like TV static". While the "stuck on camera" noise effect is undesirable in regular rendering, .it

 help denoising because it maximizes the possibility that the noise shape will remains consistent around a pixel between adjacent animation frames. This, in turn, reduces the possibility for flickering "splotchiness" on the final denoised results (which can be really distracting).
