Instagram is a great platform for sharing photos and videos with friends and family, but it can be tough to get started. If you want to start using Instagram but don’t know how, this guide will show you how to boomerang an existing video on Instagram. To boomerang an existing video on Instagram, first open the video you want to copy and press “Ctrl + C” (Windows) or “Command + C” (Mac). Next, open the Instagram app and go to your profile page. Under “Photos & Videos,” tap the three lines in the top left corner of the video you just copied. Then, tap “Boomerang.” Finally, choose a destination for your boomerang and press “Start.” If everything goes according to plan, your original video will reappear in reverse in your Instagram feed seconds after it finishes playing in the original app. Be sure to follow your original account so that you can see both versions of the video at once! ..
