Saw-toothed edges despite the use of antialiasing

Hi! I’m using a 4k display and I’ve tried all the types of anti aliasing that Unreal engine 5 has, but still, when I get into the cinematic camera I’ve created for the game shots, the edges of the objects appear in the image with very unpleasant saw teeth.


In camera

off-camera
It can only be the fault of the fluxes that I have applied as post-processing materials but there must be a solution, right? I am open to any suggestions.

Best regards and many thanks in advance.
