Video View Counts on Instagram
Below a video, you can see a count of how many times it's been viewed. A video's view count is visible to anyone who can see the post. Note that you're not able to see the number of views for videos that you've shared as part of a post with multiple photos and videos.
A video's view count doesn't include video loops, and a view is counted when a video is watched for 3 seconds or more.
Keep in mind that view counts will only show up on videos that were uploaded after November 19, 2015.
It may take some time before a video view shows up. If video views aren't showing up, try checking back later. Note that you can't see the number of video views if your video is part of a post with multiple photos and videos.
Also, keep in mind that video views only include views from within the Instagram app, and not from other places like an embedded post or from a browser. If your account is set to private, you may not see the video view count until your video has reached a certain number of video views.
Video view counts will only show up on videos that were added after November 19, 2015.
