A video converter may refer to any of the following:
1. A video converter is a hardware device that turns one type of video signal to another. Examples include VGA to DVI, DVI to VGA, HDMI to DVI, or VGA to composite video. You may need a video converter to connect an older monitor to a new computer or a new monitor to an older computer.
Keep in mind that each video format has different video resolution and capabilities and converting a signal may give a lower quality signal. An example is converting DVI to VGA since DVI has a higher video resolution capability than VGA. However, with some setups a video converter may be the only option even with a loss of quality or performance.
2. A software video converter is a software program designed to convert one native file format into another format. For example, WinFF is a great video converter that converts a video file into many different formats.
