Annoying light flickering normally and with depth of field.

[n.NOPE]

Hello. I hope y’all are well.
I’m trying to render a video using UE 5.1 + Lumen and I’m facing this very annoying light flickering issue that’s separated to 2 categories.

1. Static shot light flickering
2. Depth of field light flickering due to AA.

Here are 2 clips showing the issues:
1: (on the bottom skirt there’s constant light flickering with nothing moving in the scene.)

2: (the flicker you see on the wheels is caused by Anti-Aliasing. If I disable AA from Movie Rendering Queue this flickering goes away but the quality is overall pretty bad in comparison.)

I tried many different things like a few solutions like different rendering methods/parameters, and increasing different quality parameters, but I can’t seem to know enough about UE to figure this out by myself.

Let me know if you need any more information. Thank you in advance.

Hi, I have the same problem with yours. My solution is in movie render queue, I set the AA method to none and increase the spatial and temporal sample count 8 & 16 respectively. The cost of this setting is the time render is double. Hope this help and let me know is you have another solution.
