Denoising Animation

[Vyacheslav Volkov]

Hi, I have few questions.

We are studio who is working usually with vray and we are rendering the animations. And the process is simple, we render multiple images and denoise them later.

Our render farm has strong cpus and very cheap graphic cards that's the reason why we are denoising images after all the frames are done, using vray denoiser tool.

Right now I am checking how corona denoising works does it uses gpu or cpu and if gpu is there a way how to do denoise when all the frames are done later?

I have found the way how to denoise single image saving CXR file, but I haven't tested it yet with image sequence. Does it work with image sequence? And is it friendly for animations?

Thanks, hope everything is understandable., Cheers.

Corona denoising at present is CPU only.

You can use "Save data for later" and save to CXR format, then Denoising using the Corona Image Editor. It is possible to batch script the CIE, so that you can indeed denoise animations which are saved out as a sequence of files.

See https://forum.corona-renderer.com/index.php?topic=16428.0

Thanks, that's exactly what i was looking for :))

Cheers, have nice day :)

Hi, JFYI there is a bug in current version of command-line CIE which is being used by the batch script. A workaround for it is to select particular input element (instead of * symbol meaning all elements, see Help.txt for further info). The bug is already fixed and the fix will be in the next daily build.

Apart from the added control later on,  does this workflow provide other benefits? Is it faster to render for instance?

Denoising takes quite a lot of memory which may not be available in time of rendering (because of loaded scene, opened 3ds Max). In such cases you can denoise in CIE anytime later.

Ah cool, good to know.

Does this work also on Corona for Cinema?
In other words: are Cinema and Max users using the same Corona Image Editor?

thanks

Yes, it's the same CIE, as it's a standalone that processes CXR (Corona EXR files), and the CXRs are the same no matter where they come from :) It's also the same program on the Mac. (EDIT - but scripting for batch processing may be different on the Mac)

Thanks.
The only problem now is that Corona for C4D doens't allow saving in cxr :)

[TomG]

For sure! And already on the to-do list :)

[fla]

Yes, can't wait :)

The thing is that vray's denoising tool "interpolates" with other frames so the denoising is more consistent between frames. This is a big problem.

Hi guys, I am sure someone discussed this already, but how does optix denoiser work in a renderfarm like rebus or similar?
I am thinking of using corona for an animation, but I am wondering about denoising times for a blade server, or for a 970gtx board...
Do we need a strong graphic card for the type of interaction displayed on the demos available?

[Nekrobul]

It does not. The build with optix is in development stage.
