How to perform transitions, using keys and key modifiers, memories and custom controls, as well as Media-Store operation.
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.
DVE Keys
To Apply a Border/Edge Softness to a DVE Key
A DVE border or edge softness is applied to the edges of the DVE key and is manipulated as part of the key.

- 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.
- 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.

    - To Set Up a DVE Key
      The DVE engine allows you to apply digital video effects, such as scale, crop, aspect ratio, position, and border to a video image in 3D space.
    - To Apply a DVE to a Key (Fly Key)
      The Fly key is when the DVE engine is applied to another key type.
    - To Apply a Border/Edge Softness to a DVE Key
      A DVE border or edge softness is applied to the edges of the DVE key and is manipulated as part of the key.
  - Show Alpha
  - Masks
  - Split Keys
- 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.
- Clip Player
  The clip player offers a multiple playout channels for clips in the ITU-T H.264 (MPEG-4 AVC) and ITU-T H.265 (MPEG-H HEVC) codecs that can be assigned as a source on any bus in the switcher. Basic transport controls can be performed manually from the Clip Player pages, 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.
- Sequencer
  The Sequencer allows you to create a playlist of custom control events.
- MotionText
  Dynamically add text boxes with media that can be taken on or off screen independently of source transitions.
- UltraScene
  UltraScene provides a simplified interface for creating a show with multiple key layers and basic transitions.

To Apply a Border/Edge Softness to a DVE Key

A DVE border or edge softness is applied to the edges of the DVE key and is manipulated as part of the key.

Note:

You can only apply a border to a DVE key. Fly Keys, such as auto select keys with DVE applied to them cannot have a border applied to them. Instead, the selection is Edge Softness and is used to soften the edges of the key without any color.

Click Navigation Menu > Live Assist > MEs and select the ME and key that you want to set up.
Click DVE Key > Border.
Use the Size slider to turn on the border and adjust the size of the border around the key.
Use the Radius slider to round the corners of the key.

Note:
The radius is applied to the corners of the key image. As a border is applied to the key it expands out from the edge of the key image and the radius applied to the inner and outer edges of the border change dynamical in relation to the size of the border (their distance from the edge of the key image). This will result in the inner radius on the border appearing smaller and outer radius appearing larger.
Select a default or custom color for the border (borders only).
- Default — click one of the preset colors.
- Custom — click the arrow to the right of the Border Color area and use the Hue, Saturation, and Lightness sliders to select your own color. Click OK to apply the color or Live to apply it in real-time.
