I have polled my buyers as well and the overwhelming majority say that they simply like stills rather then a video tour. For high end properties I will recommend a good photographer that I frequently use. He does great stills and he also does a neat video tour as well. His video tours kind of start with a wide angle and then focus in on a spot. The 360 degree tours are a total laugher.
Anyways I think it is that instant gratification thing PS… Most internet shoppers like information and they like it at thier fingertips. Things that even take more then a few seconds tend to get passed over…
