Outputs

The outputs are the link between the canvas and the video display.
 If you have multiple outputs, you may be interested by the soft-edge, used to create a continuous image from multiple video projectors : Soft-edge .


Output Setup

To manage outputs, open the Output panel (shortcut : ⌘ ;).

If you want more than one output for your canvas, set your layout as desired. Learn more about setting up a canvas : Canvas .

Displays

There are different kinds of displays, please read the next sections to learn about their differences.

External Displays

The displays recognized by your computer are listed first. These are exactly the same displays listed in macOS System Preferences / Displays, such as HDMI monitors, videoprojectors, LED screens or image-processors.

Especially the main screen is clearly identified, so you do not select it by mistake. By default, the second display is selected.

Blackmagic Card

Millumin is supporting Intensity, UltraStudio and Decklink families as output cards.

While this kind of output works in a similar way as external displays, you need to choose its output format in a submenu :


By default, Millumin uses the YUV pixel-format to send the data to the Blackmagic card, but in some situation, you may want to prefer a full RGB pixel-format. Click on the settings item to activate this :

Syphon

Millumin supports the Syphon technology. It allows Millumin to send its frame to another application supporting Syphon.

Such a stream is preserving the transparency, and the server will be named Millumin4 - #CanvasName #OutputNumber in other applications.

NDI


NDI format

When your mouse is over NDI, a submenu opens to choose the mode :

By default, use the without alpha mode, unless you need alpha, so in this case choose with alpha mode.


NDI audio

The settings item to open settings for audio (these settings are shared for all NDI servers) :


  • send audio
     
    Should the NDI server send audio or not.

  • volume
     
    NDI audio volume.
     You can monitor NDI audio in the interface.


  • preview volume
     
    Volume to play on default audio output (for preview purposes).

NDI server

The NDI server is named CanvasName #OutputNumber in other application.

⚠️ Please note that INetSyphon is deprecated. Use NDI instead.
