It's easy! Just open Instagram, then click on your profile icon to get to your story. There should be an option to add a video from your gallery or to record one directly.
Adding a video in Instagram story is easy. Open the app, swipe right to access the story feature. You'll find options like 'Gallery' to choose an existing video or 'Record' to capture a new one. Instagram will guide you through the process and it's super straightforward.
The standard length of an Instagram story video is 15 seconds. However, you have the option to post multiple consecutive 15-second clips to tell a more elaborate story.
You can try using third-party apps that allow for longer video uploads to Instagram story. But be careful as this might violate Instagram's terms of use.
