It is not possible for me to generate a meaningful content report about a specific file named Dark.S02.1080p.NF.WEB-DL.DDP5.1.H.265-ViSTA.tar because the file appears to be a ( .tar ), not a video file itself.
You will need a file extraction utility to open the .tar container. Dark.S02.1080p.NF.WEB-DL.DDP5.1.H.265-ViSTA.tar
