Render at lower resolution & then upscale using AI

[hurrycat]

Hi all,

I am typically sitting at around 4 hours to get a 4K interior shot at around 3-4% noise level on a 3970x 32cores (which usually means leaving the PC rendering overnight) because I like the crispiness and the details, but most of my clients find the IR CPU-denoised 2K results (10 minutes at most) sufficient for most things (maybe up until the final delivery).

I am sure many of you are rendering at lower resolutions and the upscaling so I want to ask if there is any AI upscaling software you have had good results with and would recommend?

Thank you

I used topaz in the past, was actually pretty impressive.

We use Project Dream by Pulze in our studio. The problem with upscaling images is that besides making a larger resolution image you often also need to enhance / fill / create the details in the new pixels. So something like Topaz or other simple upscaling solutions are not great in this particular case. And more often than not controlling the amount of extra detail created is more powerful than simple upscaling.

AFAIK newer Topaz versions also have generative upscaling capabilities. You can always download trial version and see if it works for you or not.
