So there was a recent a update on IG that allows you to view the current views of your videos much like you see on FB. All you have to do is to view that video post on IG app. If you want to see the most current view, all you need to do is refresh it by swiping down. If you need more info about this there is an article about it a few weeks back: http://www.theverge.com/2016/2/11/10966522/instagram-adds-video-view-count Hope this helps you out.
I'm really sorry to disappoint you but unfortunately this is not a feature that Instagram has implemented as of yet or if they ever will. Instagram is meant to be a mobile social network, unlike its parent company Facebook, so it focuses most on it's mobile capability. There are definitely some analytic tools for Instagram like Iconosquare that may be able to give you that kind of specific information, with a fee of course, so you may want to ask them if that is a capability of theirs.
