How to perform transitions, using keys and key modifiers, memories and custom controls, as well as Media-Store operation.
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.

- 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 three basic types of video sources, external, internal, and follows.
- Video Layering
  How video is layered in the output of the switcher depends on how an ME is re-entered onto the other, what keyers are on-air for the ME, and what order the keys are in.
- 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. 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 ME, MiniME™, or scenes. Up to 100 memory registers per ME, MiniME™, or scene 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 ME, MiniME™, scenes, Aux Buses, and DVE settings.
- 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. These files are stored into Sets on USB drive. 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. Each ME, MiniME™, and MaxScene have their own Media-Store channels.
- Clip Player
  The clip player offers a single playout channel for clips in the ITU-T H.264 (MPEG-4 AVC) codec in specific HD formats that can be assigned as a source on any bus in the switcher. Basic transport controls can be performed manually from the Clip Player page, using custom controls, or through AMP commands.
- 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.
  - Recording/Editing Custom Controls
  - Custom Control Pause Mode
    The switcher can be set so that each command is automatically separated from the previous command by a pause equal to the real-time delay between events as you enter them.
  - Custom Control Logical Expressions and Variables
    - To Create a Custom Control Variable
      Custom control variables can be used in logical expressions to track values.
  - Custom Control Events
  - Running a Custom Control
  - Custom Control Names and Mnemonics
  - Deleting a Custom Control
  - Copying and Pasting a Custom Control
- Sequencer
  The Sequencer allows you to create a playlist of custom control events.
- MaxScene
  MaxScene provides a simplified interface for creating a show with multiple key layers and basic transitions.

To Create a Custom Control Variable

Custom control variables can be used in logical expressions to track values.

Click Navigation Menu > Custom Control > Variables.
Click Create to create a new event, or Edit to edit the currently selected variable.
Enter the values you want for the variable.

Tip:
Variable values must be an ASCII string or numerical value. The value must be a number to perform addition, subtraction, or logical comparisons.
- Variable Name — enter the name you want to use for the variable. Names are case sensitive.
- Current Value — enter the current value you want to apply to the variable. This is the value that can be tested against and edited using CC-Logic and RossTalk.
- Default Value — enter the default value you want to apply to the variable.
