Hi guys,

Are there any tips and tricks for rendering an animation with Corona? I searched the forums but I cannot find any recent posts. My main problem is denoising.

How can a Corona animation be denoised? Or it is better to render it as exr and try to denoise it later on in post? Because as far as I can see temporal denoising is not possible with Corona?

Also my render times, to get decent noise are around 25 min/frame on a 3950X which is extreme considering this https://forum.corona-renderer.com/index.php?topic=15448.msg97645#msg97645 animation was 30 minutes on a 6 core old Intel machine. My scene is quite simple but I have a couple of Led strip lights (planes with corona light material on them) which are close to walls or pieces of furniture. I also have huge glass windows with renders from outside to inside. Is there any way to speed up glass rendering?

Thank you!

Hi its depent many parameter

1- remove all emit light in coronalightmtl . its reduce your noise
2- use Intel AI Denoise. it's awesome...
3- use path trach for 2 methods in gi
4- To be honest you must use render farm. with a local render machine, you can not work perfectly
I suggest foxrenderfarm.

PLEASE DO not use PT + PT for interior animations if you are looking for descent render times.
use Pt+ 4k cache or Pt + UHD if you have problems with 4k cache

There aren't really any special render settings for animations. If a frame looks good rendered as a still, it will also look good as an animation frame.
In animations, usually the quality can be a bit worse, because when an image is in motion, it is harder to spot the little imperfections.

You need to remember about correct UHD Cache settings to prevent flickering - https://coronarenderer.freshdesk.com/support/solutions/articles/5000515648

Denoisers have no temporal consistency unfortunately. If a denoiser does not seem to work well enough, it is a better idea to render slightly noisy frames and then denoise them in 3rd party software.

so what your suggestion. Topaz AI Denoise? or in After effect.
