Im looking at re-rendering some university work with Corona and im wondering if anyone has successfully done any cinematic animation with it yet?
Should i wait for the adaptivity to come in a few versions? Are there any settings i should change? (im thinking locked noise pattern might be a start).
Id appreciate some guidance on whether it is worth waiting for the adaptive stuff to be implemented.
Thanks
Jack

NO. :- )
I did few small anims, very simple space, almost infographics... but the locked noise is something that looks completely horrible. It gives you this "Do I have dirty monitor or broken windows?" feeling.
Regular noise looks much more "pleasing". Of course, zero noise would be much better.

This is a test frame i did. It took 45 minutes, which is actually half the time it took for mental ray surprisingly. However given that im much more experienced than i was 2 years ago the lighting is much more efficient. However the project is about 10 minutes long so we are talking about 13500 hours of rendering on one machine!!! (i have some render nodes too so its not so bad). Im hoping there will be some significant speed ups in later versions of corona to enable me to do this but id like to start relighting and retexturing if it will be possible in the future to crank out some quicker frames.

There is no so complex animation, its only test for rendertime and motion blur and Dof with Corona render/
Project for Stock's and advertisement background for beginning of different projects//
Render 1 frame 19-20 min res 1920/1080 full HD on I-7 3.70GHZ
24 hours on renderfarm from 4 I-7 machines///
i am waiting for Adaptivity in Corona for more complex and long animations/
now it's it is simply impossible from point of view to relation's /Time-quality-noiseless//

Juraj, do you not run the risk of dancing speculars with the non fixed noise? I appreciate if you let the image clear right up its less of a problem, but if your having to cut it fine I would think the consistent grain would be less noticeable but perhaps I need to try both.

1. The static noise pattern looks absolutely horrible in animations, much worse than moving noise
2. The static noise pattern has to be disabled for some denoising apps/plugins
3. There have been some successful animations made in Corona - including (half of ;) ) this one: https://forum.corona-renderer.com/index.php/topic,10893.0.html

OK I bow to your collective expertise on this I will uncheck that box and see what happens.

@Ondra & Maru,
Do you have any tips for settings adjustments for animations? Is there anything i should be disabling to encourage faster rendering or any caches i should be saving? Any flicker issues?
Thank you
Jack
Also those space idents are amazing!

Yup, I was about to link that article. Other than that - no special treatment required. What works for stills, will also work for animation.

It matters much more when there is still a lot of residual noise. The static noise looks like filter, it's extremely noticeable. "dynamic" noise can look like shimmering, but it's far better of the two bad options :- ).

I've completed quite a few mechanical engineering animations using Corona with great results. Lots of metals and highly complex components.
Regarding the noise, I disable lock sampling pattern which does create the dancing noise however that is quite easily removed in post. I'm using Denoiser II from Red Giant and it works perfectly. Lock sampling still works but not as well (depending on what you use for noise reduction in post).
Since most of my animations are 5-10,000+ frames long, render speed is extremely important... so by leaving a bit of noise in your renders you can reduce frame time a bit. Find the threshold of just enough noise that your post production can remove without smoothing things out too much. That said, I still need to work on tweaking settings to reduce render times.
-
I might start off with the scene that took the longest to render in MR as a starting point. If i can get the render time down on that the rest should be easy.
Thanks
Jack

I did this chair anim and most of the balls in Corona:

In my personal opinion, in fly-through animations, I prefer static noise, instead random noise. =) It's much more pleasant. With random noise on every frame, it looks live we have some "animals, bugs, insect" on the wall )) Also, my stupid client recognized the random noise, but not the static noise. =)

That is a strong argument. :)

This is my old discussion
https://forum.corona-renderer.com/index.php/topic,4838.0.html
And, as you can see here (the *.gif), the static noise is much better

All of our work is rendered with Corona, you can check it in our app for iOS (Bone-Studio in the app store) and you can check one of the firsts videos we did in our website (we have the app more updated than the website):
http://bone-studio.com/en/?portfolio=casacom-gigabit-pof
We also have a 3d animated character integrated for a tv series pilot episode, btu it's private yet, I'm willing to share it but I don't have green light yet.
So far not a single problem rendering complex 3d animations with motion blur and dof in Corona, it has been a lot more stable than the old mental ray or iRay, the only advice I will give you is to try to cache as much as possible as alembic or point cache, this will make your renders more stable, but I think this is a cross-platform advice, no matter your render engine :)
Cheers!

Hmm.... for me, static noise is just terrible. If you have a little random noise then that's at least somewhat like film grain, which most people are very familiar with seeing in motion pictures. Static noise just looks terrible on walls for example. I can't see any scenario where you'd want to use it, and as someone earlier said, most de-noising algorithms won't work with static noise either.
We've done quite a bit of animation work in Corona recently and we'll be publishing it very soon. Here's one for now:

But in your video, on the fireplace, the random noise it terrible =) In my opinion, with static noise, you can reduce the noise flickering =)
Anyway, stunning lighting! O_O

Thank you ;) Yes, I agree that there are some noise issues in that shot, on the fireplace. But I don't think it would look any better static. It just needed more passes. We encountered some issues with incorrect bump mapping values as a result of going from 1.3 daily to 1.2.1 on a render farm, which caused this, so we did our best to re-render and de-noise. I think it's an acceptable amount of noise but it could be better, definitely. It seems that issue is now gone forever from 1.3 onwards too, which is good :)
-
Mmm.. look at this gif. Static noise is more pleasant that random noise. =)
-
Well that's a crazy amount of noise - far more than you'd ever allow for a final render, I imagine.
The reality is that you want minimal noise in your work no matter what you're doing, and when you do have a little noise still visible in some areas it is always better that it's random, so it looks more like film grain and is compatible with noise reduction software as well, so at least you have a chance to deal with it in post.
-
I've rendered lengthy animations with both with locked and unlocked noise and as Alex was saying, it looks more like film grain... which people are used to seeing. Static noise appears strange because it's atypical.
Do a few tests with a denoiser plugin in post. It works better with unlocked noise as it samples more than one frame, detecting what changes and interpolates the smoothing. Then you just tweak it if you need to. If you lock the pattern, the results aren't as good.
Here's how Red Giant explains their Denoiser II plugin http://www.redgiant.com/docs/doc-on/denoiser-II/howitworks.php
-
Thanks ill take a look. Ive seen a fair few people mention that redgiant plugin. I have a few of their other plugins. Ill see if they offer a trial and give it a go.
Thanks
Jack

For us the thing is that up to certain level of noise static noise is less awkward, but when you reach certain level of quality static noise seems weird and random noise feels more like grain, so if you are going to let the frames to refine up to a good level of noise then random noise will feel better.
We always use random noise.
Cheers.

I'm working on an animated short film that is aiming for a photoreal look. 'Cyan Eyed' is a steampunk themed action adventure with a few hero characters (some with clothing and hair) and lot's of detail. There is currently not too much to show in the way of renders, but you can check out some of the concept art that has gone in to it and extrapolate from there how much work will be needed to complete it:

Actually, I can share two images recently rendered with Corona. These two robots are two of the main characters of the film. There is only a default grey shader applied to all geo except for a few select surfaces that have simple glass and light material shaders (proper look dev is coming).
Enjoy!
