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 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.

- 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.
- 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.

    - 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 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 18 (4 in UHDTV1) independent channels of video with 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.

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.

The DVE resources for this key may not be available. Depending on how your switcher is configured, you may be asked to steal the resources from another element, or be prevented from using the resources.

Note: The DVE Freeze feature is only available in SD or HD video modes.

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 Key Fill and select the video signal you want to use for the key.
Click DVE > Position / Crop.
Use the X-Size and Y-Size sliders in the Positioning area to adjust the size and aspect ratio of the key.
Note: Click the Aspect buttons to lock or reset the aspect ratio of the key. If the aspect ratio is locked, size adjustments are applied to both X and Y to maintain the current aspect ration of the key.
- Lock — toggle ON to lock the size adjustments to the current aspect ratio of the key. If you adjust the aspect ration of the key and then lock it, the size adjustments will maintain the new aspect ratio settings.
- Reset — reset the aspect ratio and size to the default settings of the key.
Use the X-Position and Y-Position sliders in the Positioning area to adjust the position of the key.

Note: Click the Origin button to select the origin point for the key. Position adjustments are relative to this origin point.
Use the Left and Right sliders to crop the left and right sides of the key.
Use the Top and Bottom sliders to crop the upper and lower sides of the key.
Click Mask to apply a mask to the key.

Refer to the section To Apply a Border/Edge Softness to a DVE Key for information on applying a border to the key.
