Digital Video Switcher

A digital video switcher can be used to build a small studio or production site easily and efficiently. A digital video switcher is also known as a video mixer and is the brain of a production. This equipment has really advanced in recent years thanks to the latest TV production technology. Today’s TV production crews can set up multiple cameras and a video switcher in a short amount of time and the studio can be set up just about anywhere now thanks to the portability that a digital video switcher allows. An added benefit is that editing is so much easier and quicker now than it ever has been too. At the studio site, the program can be edited while being filmed through the video switcher or you can have it assembled together for editing later. This saves not only a lot of time but a lot of money as well on editing.

A digital video switcher or mixer can switch between cameras in a live performance and can be used to time cuts and dissolves to music when needed. You can mix sound as well with a video switcher.

Modern effects can be added that can involve several devices that have to be driven in synchronism. These effects may be such ones as the playback of short animations or special sound effects that are synchronized a switcher mix. The control signal in the digital video switcher can combine two video signals into a single signal. Composite video signals can be produced by the control panel by combining the pixels from one video signal with that of another video signal. These combined signals represent a picture of the transitioning between image signals from two external signals.

Television production sites use various input sources to input images into a digital video switcher which then outputs the transmission or recording from a selected input signal. A control processor is used to control the switching unit to provide the video output signal. As the switcher receives video input to the M/E amplifiers, combined selected signals will then produce the video output signal.

Video switchers have myriads of inputs, outputs, knobs, T-bars and faders. It will switch more than one camera to several cameras automatically or manually. Before you select a video switcher for an amateur or professional studio, decide if you want it to have a T-Bar. One without a T-bar will have basic simple effects and will be easier to operate. A VJ style production will benefit from not having a T-bar because it will need the quick-throw fader rather than the steady fade a T-bar is used for. However, many directors want a T-bar that is easy to swing to manipulate the desired effects.

The number and type of inputs and outputs is another important feature to look for. It is easier to set up and use if the video switcher has more inputs as opposed to only having a few. That is because if you have enough inputs to use you will not have to tinker with them during the middle of production. A good digital video switcher will have S-video and composite inputs as well as BNC inputs.

The outputs on the switcher are just as important as the inputs. A cheaper video switcher will not have BNC connectors and not all switchers will have audio inputs and outputs. If buy one without the inputs and outputs that you need, you will have to have separate audio gear to sum the mix as it goes into the master recorder. For all-in-one sound, get a switcher that has all the inputs and outputs that you will need. Typically, the more you pay for the digital video switcher, the more features and effects it will have.
