1.2 Key Features

1.2.1 Transition

In a generic M/E architecture, each Mix/Effects Bus (BGD + a fixed number of Keys) has its own
dedicated transition generator usually limited to one transition type at a time. KAIROS offers an
advanced approach.
In KAIROS, there is no limitation on the number of transitions, types, and combinations of transition
elements (BGD, Key/Layer) per Scene. A transition can be designed to affect multiple elements (usually
layers), and each element can have multiple components. A wide variety of transition types can be
applied to a single transition element simultaneously (e.g., mix and size), and each component of a
transition has its own "Start" and "End" position called "Offset Transition," which can be adjusted
separately per transition element (BGD, Key/Layer) and transition component (Mix, Wipe, DVE, etc.)
The so-called "Next Transition" bits—selecting multiple transitions at once (e.g.: Trans-BGD, Trans-
Layer-1, Trans-Layer-4, Trans-Layer-5)—will automatically monitor the corresponding LAH-PVW (Look
Ahead Preview), and the multi-selection made can be saved as individual setting(s) within the provided
memory systems (Macro, Scene).

1.2.2 Scene

A Scene is the equivalent of a ME on generic switcher with unique enhancements regarding:
- Number of Layers defined per Scene
- Source Options defined per Layer and per Scene (see next page "1.3 Naming Convention")
- Unlimited Transitions and Transition-Combinations including combinable Transition-Types
- Cleanfeed adjustable per Scene and per Layer
- X/Y-Resolution adjustable per Scene
- Separate set of Macros per Scene
- Macro assigned to be executed when a Scene receives a tally
- Color-Theme per Scene
- Scenes can be treated like any other regular cross-point (e.g., Cameras, Video-Server, etc.)

1.2.3 Layer

A Layer is like a Keyer on a generic M/E-type switcher for the purpose of compositing. A Layer differs
from a Keyer in that it can contain combinations of multiple Effects (attributes). A specific attribute can
be repeatedly applied to the same layer with differing parameters. As an example, a single layer could
have multiple chroma-keys applied with different key colors selected so as to fix a poorly lit chroma-key
background. All Layers, including BGD-Layer and Aux-Buses, are capable of enabling Bus-Dissolve,
whereby the dissolve-type –apart from Mix-Dissolve– can also select from Wipes, DVE's, and User
Transitions such as various programable Replay-Wipes.
Every Layer has the ability to link cross-point controls to any other Layer within the Scene. Every Layer
provides its own Color-Theme for the GUI. Layers can be grouped for more refined control. Each Layer
can treat its selected source to automatically fit into the specified Scene-Resolution, be kept in original
size and position, or be adjusted by the user. "Source Options" allows the user to specify the required
sources and their designated position per individual Layer-Bus, which will be reflected in the GUI and
on the Control Panel.
Any Layer can become like the BGD-Layer. The "Preset enable" function is selectable per Layer, which
turns a single bus layer into an A/B bus layer, where the user can preset a source on the B bus to
transition to. Layers, which have "Preset enable" active (such as Background-Layer where this function
is enabled by default), can also mimic a behavior mainly used in Automation (Run-Down) application:
- "Swap" mode is the default and behaves like any generic A/B-Bus. So, when executing a Cut or Auto
transition, the sources selected on the A-Bus and B-Bus will swap after the transition is completed.
- The "Next" mode works like "Swap," except that after the transition has been executed, the B-Bus
source selection will auto advance to the next source in the bus as user-defined in "Source Options" in
order to mimic an Automation system. If necessary, the auto-selected B-Bus cross-point can be
manually overridden at any time. When reaching the last cross-point on B-Bus, the auto advance will
stop and the B-bus will hold the same source selection.
- "Loop" mode works like next mode, but when reaching the last cross-point on B-Bus and executing a
transition, the B-Bus next source selection will loop back to the beginning of the "Source Options"
assigned to that bus.
