In general, video compression works by removing redundant data from the video signal. Some common video compression formats include MPEG, H.264, and VC-1. There are many different types of video compression, each with its trade-offs in terms of quality and efficiency. By reducing the file size, video compression makes it possible to store more video on a given storage device or to transmit video over a limited bandwidth network. Video compression is a technology that is used to reduce the size of digital video files.
