Back to iOS 6, you didn’t have the ability to zoom while taking a video and that’s was a bad something, many times there is a lot of things I like to zoom in while I am capturing a video for me and my friends.. So right now you can do this in iOS 7.
Think twice before dismissing this feature because real-time zooming during video capture allows for some interesting possibilities normally associated with camcorders.
I can easily imagine this being even more useful on a 12-megapixel camera with improved night shooting rumored to make its way inside the iPhone 5S…
To use zoom during video capture, just set the Camera app to Video mode by swiping left or right.
Upon hitting the big red red button to start recording, simply use the pinch gesture to zoom in and out during video capture. You can also tap-to-focus on your closeups as you’re shooting video.
To zoom out footage, pinch out anywhere on the screen or use the handy slider at the bottom part of the interface. Unfortunately, the slider doesn’t appear until you zoom in on the video.
