What Counts as a video View on Instagram?
3 is the magic number
On Instagram, when a client sees your video for over three seconds then it will consider it a view and your video will get one count as a view. So when you see your video view - it's what's seen for more than 3 seconds.
As you probably are aware, Instagram gives a great deal of significance to client commitment than Instagram likes and shares, so more than 3 seconds = engagement. If the user scrolls past your video after one second than it assumes the user is not interested in the content.
The same measurement is on Instagram stories - more than 3 seconds = 1 engagement view.
Does Instagram count same user views?
No - same as if you like a post multiple times (which you can't really) - the video view only counts once from each user no matter how many times it's being watched.
