Shortly after the launch of the Stories feature on Instagram, or Stories to InstagramThe company added a feature for streaming videos similar to what is already available in Facebook. The problem it is trying to solve is that if you watch a live video stream on the service, then you can not watch it again.
So Instagram decided to allow you to save the videos. Once a show is over you can just do click on the Save button in the upper right corner of the application.
The video will disappear again from Instagram, but it will be saved on your mobile camera roll.
The video will only be saved from the streamer's side so you don't have to worry if the duration of the stream you did something you liked.
Unfortunately, the feature only includes the video itself. Comments, likes, and views disappear forever.
It is also worth noting that you can save the video only as soon as it is finished, so there is no turning back if you forget to press the save button.
