If you hold your iPhone vertically, the way you talk on the phone, the recorded video will in 9×16 aspect ratio and plays sideways on the computer or HDTV screens, which expect your video to be 16×9 aspect ratio. Videos recorded in landscape mode could be upside down if the home button is on the left hand side. There is an easy way to fix this problem, with the help of some third-party software to make it work. The steps that follow will help you rotate iPhone video to make it play correctly on your computer or big screen TV.
