Speed up Arnold video rendering

[g.gracias]

Hi,

Im trying to render a video in hires (1920x1080px) in 3ds max 2022 with Arnold version: 4.3.0.78. Lowres Video link:https://we.tl/t-0dmVQ5tvEH

It has 300 frames and duration is about 10 seconds.

Going with my current settings attached screenshot. It is taking me 38hours to render the 10seconds video.(7.4 mins per frame).

The video quality is decent and clear. Is there a way to speed this up and still get a decent hires quality video?

Below are my system specs:

Processor: Intel(R) Core(TM) i7-10700 CPU @ 2.90GHz 2.90 GHz

Ram: 16.0 GB (15.7 GB usable)

System type: 64-bit operating system, x64-based processor

Graphic card: NVIDIA Quadro P1000

Intel UHD Graphics 630

Thanks in advance!

How many skydome_light samples?

Is there a reason why you have Adaptive Sampling enabled?

(update your MAXtoA version)

Hi,

Thanks for the quick reply. skydome_light samples are set to 1

No reason tbh, I went through a couple of settings people shared to try what could work best.

Should i turn it off?

Will update my MaxtoA version.

Thanks.

It should render faster without adaptive.

Tried it. It came down from 7.41 min per frame to 5 mins per frame.

Below is my settings:

Attached preview of the render quality:

anyway to bring it down to 3 mins per frame as I have 300 frames to render and with 5per frame it would still take 25 hours to render the 10second video.

Thanks in advance. 😄

I would need to look at the scene. Can you upload it somewhere?

The Adaptive Sampling Settinge makes no sense. The threshold should not be 0. It should be between 0.01 and 0.02 I think. And the Samples Max must be higher the the Camera Samples. But I think this is not the reason for a long render time.

Hi,

Thanks for that tip. Switching off Adaptive Sampling did help reduce the time by 2 n half minutes which is a great jump - a helpful tip from Lee Griggs. Would you know of any other way to reduce the long render time? what you think about my system specs? I tried the denoising thing but couldnt understand how to do it right..will try a few more tutorials. and see if that helps to speed up time.

My current settings are :

Preview AA: -5

AA : 4

Diffuse, Specular, Transmission, SSS and Volume indirect - 1

Ray depth : all 1 except diffuse is 4.

The output is good. a little noisy though and time 3 mins per frame. Hopefully i can get a good quality render for 1 min per frame as my videos would mostly be around 2 mins and thats alot of hours to render.
