A video switcher is an essential tool in audiovisual production that primarily functions to mix different video sources. This involves combining multiple input signals—such as cameras, graphics, or pre-recorded material—into a single output stream for live broadcast or recording. By utilizing a video switcher, operators can seamlessly transition between these sources, providing a dynamic and engaging viewing experience.

For instance, in a live event setting, a video switcher allows the operator to switch between several camera angles or integrate graphics, ensuring that the audience receives the most relevant and captivating content in real time. This versatility makes it a critical component in various applications, including television production, streaming, and live event management.

The other options do not align with the primary functions of a video switcher. Increasing volume levels pertains to audio mixing rather than video switching, storing video footage refers to recording and archiving rather than mixing sources, and editing audio tracks falls under audio post-production tasks, which are separate from what a video switcher is designed to do.
