Open the Camera application in video mode, then tap the video thumbnail at the bottom of the screen.
Your video images are displayed in full size. Swipe or flick your finger left or right to scroll through your videos (or photos).
For quicker, direct access, you can tap the screen to display smaller film-like images of your videos across the bottom of the screen. Swipe or flick horizontally to quickly scroll through them, then tap the one you want to view.
The pinch-to-zoom gesture allows you to easily zoom in and out of the displayed video image. Spread your fingers to zoom in and pinch your fingers to zoom out.
Continue the pinch in gesture on the video image to display your videos in reduced size which allows you to swipe a video image up, off the screen to quickly delete it or swipe down to share it.
