How to use denoise node with image sequence in the compositor

Hi, I’m trying to use the denoise node with this image. I’d like to know I am using it properly please. I hope you can see the sort of artifacts the node seemed to create in the dark inside of the cab in the image. I can’t seem to find any info online to put my mind at ease.
Thanks a million!
