Adjust Video Recording Settings in IOS 9 to Save Space
Among the best new hidden features in iOS 9 is the new option to change the default video recording settings, which should help you save some space when needed.
If you go to Settings> Photos & Camera> Video Recording, you will see two options: Video Recording and Time Lapse Recording. Tap any of them and you can adjust the default quality and frame rate, which can seriously help you save space on your device when you need it. Apart from this, another small mini-feature in iOS is the ability to zoom in on videos. Now you can do it by pinching and zooming just like in the photos.
