Switcher Basics
This section gives an overview of how video is controlled by the MC1-MK. This includes video sources, video
layering, and preview. For information on setting up crosspoints and video inputs, refer to the MC1-MK
Installation Guide.
Video Sources
The MC1-MK has access to two basic types of video sources: external and internal. All video sources can be
assigned to video source (crosspoint) buttons. By pressing a crosspoint button on a bus, the video source assigned to
that button is selected.
•External — External video sources come from SDI inputs on the rear module.
•Internal — Internal video sources come from internally generated video, such as any of the four internally
generated Logo channels, or an internally generated black.
To select a video source on a bus, you must identify the bus you want to assign a video source to and then press the
crosspoint button you want to select on that bus.
Video Layering
Key layering is fixed for the MC1-MK and starts with Background and proceeds to Keyer 4.
Figure 3.2 Video Layering
Video Preview
Video preview allows you to use an additional monitor to preview what the next shot is going to be. The Preset bus
of MC1-MK shows what is selected for the next transition. This includes the keys and background video sources
that will be on-air after the next transition.
Overlay
The overlay feature provides one layer of text, in real time, as a source for any Keyer. The text can be from an EAS
or LTC source.
Multiple MC1-MK Operation
DashBoard enables you to have multiple On Air Control interfaces open with each interface for a specific MC1-MK
Master Control Switcher. Refer to the MC1-MK Installation Guide for details on setting up multiple cards.
Channel Ganging
The MC1-MK can operate as either master or remote channel depending on the role assigned to it in the Remote
Control tab of its Configuration interface.
Commands
The master MC1-MK passes all commands described in Table 3.1 to each remote MC1-MK with a valid
connection to it.

MC1-MK Operation Guide (v11.0) Keying • 19
Keying
Keying is the term used to describe when you insert (or electronically cut) portions of one screen 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). This chapter provides a summary of the
MC1-MK keying features.
Keyers Overview
MC1-MK includes up to four high quality 3G/HD/SD-SDI video keyers.1 In addition to the external Key Video and
Key Alpha source, there are also four internal static/animation playout channels. This enables the keying of external
devices such as character generators, graphic systems and EAS devices into a program feed and/or keying with four
internal logo channels. If you have the 3G Video Mode enabled, only two keyers and two logo channels are
available.
The card offers full key control with shaped and unshaped keying, self key or auto key, with clip and gain control.
Figure 4.1 Keyer Controls
1. Keyers Tab
Each keyer has a sub-tab that enables you to select video sources, key types, and adjust transparency, clip, and
gain. The MC1-MK supports Auto Select and Self keys. The External sub-tab enables you to specify the router
source that feeds input on the KEY VIDEO Input or KEY ALPHA Input used as the External source when
configuring keyers.
2. Logos Tab
Each logo channel has a sub-tab in the Logos tab that enables you to specify the media files the channel uses.
Refer to the section “Loading Media Files” on page 40 for details.
1. Only two keyers (Key 1, Key 2) are available when 3G Video Mode is enabled.

3. Program Keyer Select Buttons
When lit red, a button indicates that specific keyer is currently on-air on the Program bus. Selecting a button will
immediately perform cuts on that keyer.
4. Preset Keyer Select Buttons
These buttons are used to choose which keyer is included in the next transition. Note that depending on a
Personality tab setting, once a transition is performed, the buttons are no longer lit.
Key Types
The MC1-MK supports the following key types:
•Auto Select — An Auto Select Key uses two video signals: the Key Alpha is used to cut the hole in the video,
and the Key Video is used to fill the hole. For external keying, the source on BNC 2 is the Key Video and the
source on BNC 4 is the Key Alpha. For internal sources, the Key Video and Alpha are generated internally (BNC
2 and BNC 4 are not used). The Key Alpha Type is automatically set to Shaped.
•Self — A Self Key uses only one video signal: the luminance (or brightness) of the Key Video is used as the Key
Alpha. For external keying, the source on BNC 2 is used as the Key Video and the Key Alpha (BNC 4) is not
used. For internal sources, the Key Video is internally supplied (BNC 2 nor BNC 4 are used). The Key Alpha
Type is automatically set to Unshaped.
Key Alpha Types
You can specify a key alpha as one of the following:
•Unshaped (multiplicative keying) — With an Unshaped Key, the Key Alpha luminance value mixes linearly the
Key Video with the Background. Shades of gray, in the Key Alpha, are translated into transparency levels, giving
the key a soft edge. Self Keys are set to Unshaped by default.
•Shaped (additive keying) — With a Shaped Key, the Key Alpha cuts a hole in the Background based on the
luminance value of the Key Alpha and adds the Key Video to the Background hole. Shaped Key alphas are
sometimes used with Character Generators to cut very precise holes for the Key Video fill. Auto Select keys are
set to Shaped by default.
Configuring a Key
The MC1-MK provides the ability to associate each keyer with the following sources: external key video/fill, or a
logo channel. This section briefly describes how to set up Key Alphas, Auto Keys, and adjust the clip and gain
values, and how to apply a box mask.
For More Information on...
• loading media files to logo channels, refer to the section “Loading Media Files” on page 40.
• performing transitions, refer to the section “Performing Transitions” on page 25.
Configuring Key Sources
You can assign any of the four logo channels or a router crosspoint as the source for a keyer. The specific router
crosspoint assigned to the Key Video source can be selected using the options in the External tab.
Leave Logo 4 assigned to Key 4 to ensure that EAS text crawls output properly. If you have the 3G Video Mode
enabled, EAS is automatically re-assigned to Logo 2.
To configure a key
1. Navigate to the On Air Control interface as outlined in “Accessing the On Air Control Interface in
DashBoard” on page 11.
