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 Lighting to the DVE Border
Apply a drop shadow and lighting effect to the DVE Key and border.

- 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, 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, MiniME™, or Canvas. The background and each keyer can be transitioned independently.

  - DVE Keys
    - 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 2D 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.
    - To Apply Lighting to the DVE Border
      Apply a drop shadow and lighting effect to the DVE Key and border.

  - Masks
  - Split Keys
- Memory Functions
  A memory register is a snapshot of the current state of the switcher that can include one or multiple ME, MiniME™, Canvas, scenes, or chroma key outputs. Up to 100 memory registers per ME, MiniME™, Canvas, scene, or chroma key 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™, Canvas, scenes, chroma key outputs, 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. Audio sources can come from the embedded audio on an input BNC, through the 1RU Audio Breakout Unit, or from the Media-Store.
- 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 from the USB drive and make them available across all MEs. Up to 4 (2 in UHDTV1) independent channels of video with alpha for playout of stills and animations are available switcher-wide.
- 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.
- Sequencer
  The Sequencer allows you to create a playlist of custom control events.
- UltraScene
  UltraScene provides a simplified interface for creating a show with multiple key layers and basic transitions.

To Apply Lighting to the DVE Border

Apply a drop shadow and lighting effect to the DVE Key and border.

Click Navigation Menu > Live Assist > MEs and select the ME and key that you want to set up.

Tip: You can use the same procedure for a MiniME™ or Canvas. You can use the same procedure for a MiniME™.
Click DVE > Shadow / Lighting

Note: The 3D borders/lighting are not available when the switcher is operating in the SD 4 Key mode.
Click a Drop Shadow button to turn the shadow on (On) or off (Off).

The drop shadow is semi-transparent and appears behind the key on top of the background. The position of the shadow is adjusted using the border lighting settings. Effects that are applied to the exterior border are also shown on the drop shadow.
Use the Shadow Transparency slider to adjust the amount of the background that is visible through the drop shadow.
Use the Shadow Softness slider to adjust the sharpness of the edges of the drop shadow.
Use the Shadow Depth slider to adjust the apparent distance of the shadow from the key.
Use the Brightness slider to adjust the brightness of the light.
Use the Horizontal Lighting and Vertical Lighting slider to adjust the position of the lighting.

Tip: As you change the position of the light, the brightness of the bevel on the inner and outer border changes to match the shadow created by the light.
