Zooming videos
The iPhone has a brilliant 320 x 480 pixel display that has an amazing quality. The resolution of this is nearly twice that of the normal computer screen. In spite of this there are some problems you might face when it comes to viewing videos.
Once common problem you might face are letterbox columns. Standard TV shows are squarish, not rectangular. So when you watch TV shows, you get black letterbox columns on either side of the picture. Movies have the opposite problem. They’re too wide for the iPhone screen. So when you watch movies, you wind up with horizontal letterbox bars above and below the picture.
Fortunately, the iPhone gives you a choice. If you double-tap the video as it plays, you zoom in, magnifying the image so it fills the entire screen. Or, if the playback controls are visible, you can also tap the little button with two arrows on it.
Of course, now, you’re not seeing the entire original composition. You lose the top and bottom of TV scenes, or the left and right edges of movie scenes. Fortunately, if this effect winds up chopping off something important,some text on the screen, for example, restoring the original letterbox view is just another double-tap away.
