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.

- 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 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. The background and each keyer can be transitioned independently.

  - Self Keys
  - Auto Select Keys
  - 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.
  - Masks
  - Split Keys
- Memory Functions
  A memory register is a snapshot of the current state of the switcher that can include one or multiple MiniME™, Canvas. Up to 100 memory registers per MiniME™ or Canvas can be stored and recalled on the switcher. Each of these memory registers can store as little as the information of one MiniME™, or as much as the current state of the entire switcher, including all MiniME™, Canvas 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 from the USB drive. Up to 24 (7 in UHDTV1) independent channels of video and alpha for playout of stills and animations are available switcher-wide.
- 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.

DVE Keys

The DVE key allows you to apply digital video effects, such as scale, crop, aspect ratio, position, and border to a video image or another key type. When the DVE is applied to another key type, it is said to be flying (Fly Key).

Tip: You can see where DVE channels are allocated from the Status page in DashBoard.

Keep the following in mind:

Keep the following in mind when working with a Fly Key:

The Fly Key feature consumes a single DVE channel for self keys, but two DVE channels for an auto select and chroma keys.
The Fly Key feature cannot be applied to a DVE key.
The Key Invert feature is not available for a Fly Key.
When Edge Filtering is turned Off for a DVE key (not available for Flying keys), sub-pixel movement for they key is disabled. The key will snap from one pixel location to another. This makes edge alignment between keys easier but motion, such as from Effects Dissolve, will appear jagged.
