1 Introduction Avid Maestro | Engine 4K is an all-in-one digital video rendering platform. It is designed to meet the real-time graphic rendering needs of the broadcast industry. Maestro | Engine works in concert with Maestro | RenderEngine software, providing advanced graphics rendering in the highest quality possible—whether displayed onscreen or in the studio. Maestro | Engine 4K is solidly built to withstand the demands of 24/7 operation. It features dual power supplies, dual network interfaces, and software and hardware watchdogs, so should a system go offline, your production will not be interrupted. And because all Maestro graphics suite applications can control multiple Maestro | Engines 4K, you can use additional engines as live backups to your on-air systems. No need to install additional client software or have a systems administrator tethered to your machine room to manage and configure settings. The engine uses a web-based interface for all systems management, enabling you to set up and make changes to user access rights, video formats, genlock sources, input and output mapping, and other settings from any computer or device on your network—from anywhere inside or outside your facility.

Outputs to NDI
The Outputs to NDI page of the M|E Layouts configurator allows to view NDI outputs. You cannot
delete any outputs or add new ones here, because they are only configured in the Maestro | Engine
Manager (as described in the The NDI Settings topic).
Overview of Output Channels
In the overview area, all output channels are listed with information about their size, and type of
scan. There is also information how many routings filled the channel.
37Group Edit
You can use the Group Edit option to edit canvases, routings and outputs simultaneously.
The To Edit panel shows the currently defined items for the layout. Click on an item to allow for
editing. The Canvases view below is shown as an example.
It is also possible to change properties of multiple items of the same category at once. For example,
you change the size of every canvas without the need of opening the editor for each of them
separately.
n When editing multiple items, only the options with the same values can be changed.
38The Layout Wizard
The Layout wizard will guide through creating a custom layout.
Number of Canvases and Outputs
On the first page of the wizard, define the number of input canvases, outputs to window, outputs to
VE and Outputs to NDI.
It is also possible to adjust the width and height for each new canvas and output.
Additionally, if the chosen output type is VE, you can set the index number of the channel.
n When working on Linux, outputs to window are detected automatically and cannot be created
manually.
Click on the Next Step button.
39Dividing Canvases and Outputs into Parts
In this step, each canvas and output can be divided into smaller areas.
In order to do so, either vertical or horizontal cut orientation should be chosen. After hovering the
mouse pointer over one of the rectangles, a cutting line will appear. After selecting the right spot,
press the mouse to make a cut.
The cut that can be adjusted in three ways:
• dragging the cutting line,
• passing the exact value into the field above rectangle,
• choosing one of the predefined positions by clicking on a proper button.
Every cut that has been made can be undone or redone by clicking the Undo or Redo buttons.
n You can use predefined hotkeys that will make the cutting process easier. To show available hotkeys,
activate the Show Hotkeys check box.
Click on the Next Step button.
40Defining Routings
In this step, you can define which part of the canvas is displayed on which output by creating a
routing.
To create the routing, click on the parts of canvas and on the output that you want to connect. After
this step is finished, click on Route w/ maintaining aspect or Route w/o maintaining aspect.
Click on the Finish button to exit the wizard.
Saving Changes
To save the applied changes in the Layout.xml file, click on the Save changes button.
c Changes made in the M|E Layouts module will be automatically applied to the RenderEngine.
After reloading the layout or restarting the RenderEngine, all unsaved changes will be lost.
