There are many situations where you might need to resize a video and change the screen resolution. It could be because the video screen size is too big to be uploaded to YouTube, or you need to enlarge a small video to fill up your large monitor. Sometimes resizing the video can also bring its actual file size down. This tutorial will guide you through the steps required to resize a video / movie.
