Weird white artifacts in cinematic renders. Can someone tell me what I'm doing wrong, please?

Hi everybody,

I’m having issues with a project. When I render a sequence I get these weird white lines all over the foliage and some actors and I’ve looked everywhere for a solution but I’ve got nothing.

Can someone please help me?
Thank you!!
