MPEG 4 is a video format that has revolutionized the digital distribution of video. Its small size and high quality even made it popular in consumer electronics such as Blu-ray and flash memory, and still and video cameras. When recording video with a still camera, you might turn the camera 90 degrees to capture video vertically. This is acceptable when taking a still image, but a vertical video will not playback correctly on TVs or computers. To rotate the video 90 degrees, a video-editing or conversion program must be used. VirtualDub and Adobe After Effects can both do this. Tips Warnings Writer Bio
