Path Tracer Videos exporting with noise

I used to export videos with path tracer with previous versions than the last one, even in dark spaces with high render export and 4K resolution and everything was fine. It seems like in the last twinmotion update no matter what I try the video always comes out with noise. I tried to change the HDRI etc but still the result is not good. If I increase the samples number the video will take forever to export. Any suggestions? Is it the new update that has the issue? Thank you..
