Create a short Facebook profile video to wow your profile visitors
To try this feature, update your Facebook mobile app to the latest ( at least from version 81.x.x +) from Play Store. Switch to your profile and tap your existing profile picture to pop out options.
There are two video options Take a New Profile Video and Upload Video or Photo. The first option takes you directly to your device camera for video capturing while the latter allows you to either make an instant recording or choose from your video gallery. If your existing video is more than 7 seconds, just trim it.
Once you are done with the recording, click next to select profile video thumbnail. This shows the static image , just like profile picture, from the video to show on your profile before tapping to view. You can adjust the thumbnails to any part.
Then tap Use to start uploading. Your profile video will be visible in your circle's news feed. Let them view , like and comment.
