Corona settings for animation

[maru]

Also enabling blur and sharpen should help. I am actually testing that right now and will post results soon. :)

So the conclusion is that lower givsaa, more passes, and blur/sharpen help with this.
I am attaching my tests.
def - default settings
32pass - number of passes per frame
gi - gi vs aa value
blur - sharpen/blur enabled in vfb

Ok, I have not so strong hightlights as in your test, but, I don' t see any problems.

ok what is the values you use for sharpening & blurring? also default?
I've just done 1 render with 200 passes and it is still grainy, but takes an hour a frame ...:(

How many passes? Also, I think the biggest issue is when there are objects smaller than 1 px (like small branches) and there is subtle movement.

For sharpen/blur I used the default values.
You should get roughly the same render time with:
100 passes and gi vs aa set to 16
200 passes and gi vs aa set to 8
400 passes and gi vs aa set to 4

So if you set passes and gi vs aa value proportionally, then the render times should not rise.

You can also try setting light samples multiplier to 1. It should not affect render quality in your case, and will additionally cut render times.

Hi Maru,

I rendered it as above like you mentioned, but no luck...

- default corona settings
- 400 passes per frame and gi vs aa set to 4
- no denoising
- sharpening & blur on, but I've increased the blur to 1.8 so i have more blur

So last option i have is to render the animation at bigger resolution, but it means longer render times & editing them smaller afterwards again?

I'll try to send you a scene with my plants & settings if that will help...

Yes, unfortunately rendering in higher resolution usually means longer render times. But it's strange that it seems to be so problematic to remove this kind of flickering. I wonder how it would work in other renderers
You are welcome to send the scene using https://corona-renderer.com/upload

thx Maru! I did send the scene this morning ;) Just check it your side again :)
