Animation with Path Tracer- flickering

HI

This seems to be a common issue but hoping someone can offer some advice. I'm trying to render out an animation using Path Tracer to render. As what seems to be a common result, the animation has a lot of flickering in the outputted movie file.

I've tried rendering individual pngs and imported into Premiere, and using the median tool try to smooth our the noise, but this just seems to make the overall image blurry. Can anyone offer any advice on how to resolve this issue.

Thank you

In a video, the flickering is mainly caused by the "denoiser", which should often be turned off in the case of motion pictures.

A noisy image can mostly be the "aliasing filter" setting.

I would check these two settings first...
