Moire during Animation

nimonsi_5039111

Hello! Can you help? I'm creating animations in Daz3D at 1080p as image sequences, and then I assemble the renders into an animation in Blender. The problem is that there's noticeable moire on hair and skin during animation playback, and it isn't removed by Blender even though I'm using the OptiX denoiser. The only thing that helps is rendering at 4K, but that takes forever! Increasing samples doesn't help. Is there a less radical way to remove the moire? Thanks!

Here's what happens to the hair and skin when I just change the facial expression a little. https://drive.google.com/file/d/10X09Pcpml83oshpT37eYshNaUiyDCmcG/view?usp=drive_link

Thank you!

limit frames to a set number of max samples not max time

I've already done that: 800 samples total per frame, no time limits, the denoiser kicks in at 770 samples.

LOL many of my image series are only 10 samples but I do do them 1440p then composite at 1080p

and avoid emitters (use dome only not scene and I use HDR lighting)

with background images and iray mat

I am not very fussy though admittedly

About the only way to avoid it is to render in BBlender or use 3DL shaders. In DAZ, iRay renders will make Moire patterns everytime.
