Announced on June 20, 2018, IGTV is a part of Instagram that allows watching or upload a long-form,
vertical video of the regular 120 seconds video from Instagram.
The videos are up to 60 minutes long, can be vertical and full-screen.
Although there is a stand-alone IGTV app, you'll always be able to access it from inside the Instagram app. In the Instagram app, you will see a TV icon in the top right or on the profile page of a user, you will see a separate tab with IGTV logo.
To download igtv video you will only need a valid link of a video from Instagram. If you don't have the igtv video link, obtaining such a link is very easy.
