What seems like a simple idea — take video with your phone or other mobile device — sometimes turns itself on its head when you download it from the device. Literally.
Your video — which looked good on your device — is now rotated 90 degree!
It’s a ‘feature’ that your video will look fine on the device but in reality, you recorded it rotated from the true device orientation.
Fortunately, there’s a free software that will fix this for you. Handbrake is freeware that will allow you to rotate your video so that you can view it properly.
