Tips for Speed with Rendering Animation?

[blastframe]

Hello,
I'm trying to optimize my render, which has animation in it, while avoiding flickering from denoising. Can anyone help with some tips?

So far, I have the ones from this video:
Octane Render : Fast animation settings

• Render with default settings, store an image buffer, then reduce Diffuse/Specular/Scatter Depth to 0 and incrementally increase. Compare.
• Use 'Hotpixel removal' instead of Denoiser if possible
• [if Pathtracing kernel] Use 'Caustic blur' for fireflies
• Increase 'Coherent Ratio'
• Enable 'Static Noise' to reduce noise if using Depth of Field
• Enable 'Adaptive sampling' and adjust 'Noise threshold' & 'Min. samples' until much of the image's 'Noise' pass turns green.

Any others?

Hi,
my suggestions:
- most important, reduce the GI-Clamp to 10 to almost remove all the caustics fireflies, without changing the GI quality. You can go under 10, but you see a compression/contrast in GI.
- Caustic Blur needs GPU power, so if possible, keep it at default value
- Never use Hot Pixel removal, it is destructive, and never use it in conjunction with AI Denoiser! At least, never go under 0.65.
- In open space scenes, you can set the Path Termination Power to 1.
- Coherent Ratio amount depends from Max sampling, the more sampling you have, the more Coherent Ratio you can have, the reference is 1024sp = 0.35 CR
- Static Noise must be always enabled, if Coherent Ratio is greater than 0, it doesn't depend from DOF
- You can increase Parallel sampling and Max Tile to max, but you also have an increase in VRAM consumption.
- About Adaptive Sampling, pay attention that the Expected Exposure value is the same as the Exposure in the Camera Imager node. Depending on your eyes and taste, you can reduce the Noise Threshold to 0.02, but also increase it to 0.04/5.

These are great tips, Beppe, thank you! I'll try them all.

I came up with a Coherent Ratio Calculator here.

Nice!
Thanks for sharing
