Video converters are computer programs that can change the storage format of digital video. They may recompress the video to another format in a process called transcoding. The disadvantages to transcoding are that there is quality loss when transcoding between lossy compression formats, and that the process is highly CPU intensive.
Videos may also need to be converted to reduce their file size for easier sharing, storage or playback. Examples include VGA to DVI, DVI to VGA, HDMI to DVI, or VGA. It converts from a broad range of different formats and codecs to more compatible, commonly-used ones. Video converter may be the only option even with a loss of quality.
