Sharing Videos on Instagram
In addition to photos, you can record and share short videos with Instagram. These videos can only be 15 seconds long, so you may need to get creative to fit everything in! To record a video, tap the Camera button, then choose the movie icon. Next, press and hold the Record button to record your video.
When you're done, you can apply a filter to the video and share it with your friends, just like a regular photo. You can also choose to import videos you've taken with the default camera app on your phone.
