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
2D DVE
The 2D DVE keys support size, aspect, X/Y position, and crop along with the effects like advanced borders and lighting/shadow.
To Apply a Video Border to a 2D DVE Key
A 2D DVE video border puts live video into the border space around 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 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.

  - DVE Keys
    - 2D DVE
      The 2D DVE keys support size, aspect, X/Y position, and crop along with the effects like advanced borders and lighting/shadow.
      - To Set Up a 2D DVE Key
        The 2D 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 2D DVE to a Key (Fly Key)
        The 2D Fly key is when the 2D DVE engine is applied to another key type.
      - To Apply a Color Border/Edge Softness to a 2D DVE Key
        A 2D DVE border or edge softness is applied to the edges of the 2D DVE key and is manipulated as part of the key.
      - To Apply a Video Border to a 2D DVE Key
        A 2D DVE video border puts live video into the border space around the key.
      - To Apply Lighting to the 2D DVE Border
        Apply a drop shadow and lighting effect to the 2D DVE Key and border.
    - 3D DVE
      The 3D DVE keys support size, aspect, X/Y/Z position, crop, and rotation along with the addition of effects like simple borders.
  - Preprocessor Effects (3D DVE)
  - DVE Key Combiner
    Combine two channels from the same 2D or 3D DVE keyer to make independent keys that can be layered or intersected.
  - 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 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.
- 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 Apply a Video Border to a 2D DVE Key

A 2D DVE video border puts live video into the border space around the key.

Important:

All keyers on the same ME use the same border video source. If you change the source on one keyer, you change the source on all keyers on that ME.

Note:

Video Borders is only available for an ME.

Note:

You can only apply a border to a DVE key. Fly Keys, such as chroma keys or auto select keys with DVE applied to them cannot have a border applied to them.

Click Navigation Menu > Live Assist > MEs and select the ME and key that you want to set up.
Click 2D DVE > Border.
In the Border area, click Video to apply the video border to the key or Off to have it not visible. The border setting are not changed when the border is turned off.

Tip:
To seamlessly apply a border with a custom control or memory, recall the border settings with the border turned off and then turn the border on with another CC event or memory. Remember to insert a pause between the border settings and turning the border on to allow for the border settings to be applied.
Use the Size slider to adjust the size of the border.
Click the Border Fill button and select the video source you want to insert into the border of the key.

Note:
The sources that are available for the border fill depends on the ME you are using. Resource from one blade are not available to another blade directly.
Use the Transparency slider to adjust the transparency of the border area.
Use the Overhang slider to adjust the position of the border relative to the edges of the key.

Tip:
At 50 the middle of the border is at the edge of the key. As you increase the overhang the border moves further to the outside of the key, revealing more of the video in the key.
