Video Sources
The switcher has access to two basic types of video sources; external and internal.

To select a video source on a bus, you must identify the ME and bus you want to assign a video source to, and then press the source button you want to select on that bus.

- Audio and Video Processing
  Video and audio signals are processed and passed through the switcher in different ways, depending on how the switcher is being used or is set up. A better understanding of how the switcher is processing these signals help you to achieve the production you want.
- Video Sources
  The switcher has access to two basic types of video sources; external and internal.
  - To Select a Source on a Bus from DashBoard
    To select a video source on a bus, you must identify the ME and bus you want to assign a video source to, and then press the source button you want to select on that bus.
- Video Layering
  How video is layered in the output of the switcher depends on how an ME is re-entered onto the other, and what keyers are on-air for the ME.
- Video Preview
  Video preview allows you to use an additional monitor to preview what the next shot is going to be.
- Matte Source
  Matte color backgrounds (BG) are color signals that can be applied to backgrounds and keys. Color selection is done either by picking a preset color, or by adjusted hue, saturation, and luminance to create a custom color.
- Copying
  You can copy the content of an ME or keyer to another ME or keyer.
- Transitions
  Transitions are used to change the background video and take keys on and off-air. A transition can include any combinations of background and keyers for an ME. The background and each keyer can be transitioned independently.
- Keying
  Keying is the term used to describe when you insert (or electronically cut) portions of one scene into another, or place titles over background images. Keys are made up of two basic components, an alpha, that cuts the hole in the background video, and a fill, that fills the hole with different video.
- Memory Functions
  A memory register is a snapshot of the current state of the switcher that can include one or multiple MEs. Up to 100 memory registers per ME can be stored and recalled on the switcher. Each of these memory registers can store as little as the information of one ME, or as much as the current state of the entire switcher, including all MEs, Aux Buses, and DVE settings.
- Audio Mixer
  The audio mixer node in DashBoard provides a graphical interface to all the audio sources and mixer layers. An audio channel must be routed to the switcher to be controllable by the audio mixer interface.
- Switcher Sets
  The switcher stores configuration and operation data in a number of registers that contain the individual entries for items such as memories or personality settings. These registers can be stored as a single archive file, or as a register set that contains all the individual register of that type; all memories for example. Different Sets can be created for different shows or applications, allowing you to quickly locate and recall the switcher configurations.
- Media-Store
  The MediaManager interface to the Media-Store allows you to load stills, animations, or audio files and make them available across all MEs.
- Custom Controls
  Once programmed, a custom control (CC) can be played back by pressing a button. The custom control can be as simple as triggering an output GPI pulse, or as complex as recalling a specific memory register on an ME, performing a switcher transition, and selecting a group of keys.
- Sequencer
  The Sequencer allows you to create a playlist of custom control events.

To Select a Source on a Bus from DashBoard

To select a video source on a bus, you must identify the ME and bus you want to assign a video source to, and then press the source button you want to select on that bus.

Click Navigation Menu > Live Assist > Buses.
Click ME Bus, Chr Key Bus, or Aux Bus to select the area that you want to select a source on. As you select different areas, the buses for that area are listed on the row above.
Click MEX, CK X, or AuxX to select the specific bus or area you want to select a source on. With an ME there is an additional selection of the keyer, background, or preset bus that you want to select a source on. The aux buses and chroma keys do not have these selections.
Select the background, preset, or keyer bus that you want to select a source on. (ME only)

Note: Ensure that the source selected on the bus you want to enter onto the ME, aux, or keyer is valid for that destination. If the source is not valid, you will not be able to select the bus on the ME, Aux, or keyer.
Select the type of source you want to assign to the bus and then select the source.
- Physical — the sources assigned to the numbered inputs of the switcher.
- Internal — internally generated sources, including re-entries.
- Media — the output of a Media-Store channel.
- Aux Follows — use the source that is active on selected aux bus.
- ME Follows — use the source that is active on selected ME bus.
