This tab allows you to configure the output settings for the channels to be monitored.

There are four output modes in Cinegy Multiviewer:

  • Window output – the mode in which a frame is formed from the data of all the incoming MPEG-TS streams and is played in the Cinegy Multiviewer window.

  • MPEG-TS output – the mode in which a render of the incoming streams (or layout) is sent out as an RTP/UDP or SRT stream itself for playback from any accessible locations on the network.

  • Shared RAM output – the mode in which a live uncompressed stream can be sent to another Cinegy application installed on the same machine, e.g. Cinegy Capture, Cinegy Live or Cinegy Playout instance.

  • NDI output – the mode in which the NDI output stream is generated.

It is possible to configure one Window output as well as multiple RTP, NDI, and Shared RAM outputs.

It is possible to add new or remove the selected output mode configuration by pressing the "plus" and "minus" buttons respectively. If the Window output configuration is not present, while adding a new output configuration you will be suggested to choose the following modes:


Window Output Settings

Select the "Window Output" option from the left hand list:


Here use the pull-down list to choose the PC display on which the Cinegy Multiviewer window will run and define the width and height of this window (in pixels).

To expand the Cinegy Multiviewer window to full screen, select the "Fullscreen/Stretch" checkbox.

MPEG-TS Output Settings

Select the "MPEG-TS Output" option from the left hand section of the "Output settings" tab:


Here select the "Enabled" checkbox and configure the following settings:

  • Broadcast mode – choose the output transmission method (unicast or multicast).

    Changing the broadcast mode settings resets the defined channels configurations. You will be informed about it with the corresponding alert message.
  • Stream – choose the output stream protocol type (RTP, UDP, or SRT).

  • IP & port – in the unicast mode, enter here the destination station address and port. In multicast mode, enter the IP and port of the multicast group that will be used for multicasting.

SRT Output Setup

SRT (Secure, Reliable Transport) is an open source video transport protocol which operates as unicast UDP, therefore the broadcast mode must be set to unicast. Then "SRT" should be selected from the "Stream" drop-down list.

SRT can act in two modes: as caller and as listener which differ dependant on the IPv4 address within the URL.

In caller mode, a source or destination device acts as the initiator of an SRT connection. The caller device must know the public IP address and port number of the listener. The URL of the receiver in caller mode should contain the specific address of the source of the SRT packets, for example:


In this case, the application receiving the stream will reach out to the specified address and request an SRT stream is sent to that calling application on UDP port 9000. Before the request, and in case the request is terminated or the connection is lost, no traffic will flow from the source to the receiver (unlike with a static unicast configuration where the sender continuously streams packets regardless of any receiver state). This is useful when defining and starting a new receiving operation without reconfiguration of a sender, for example a mobile device requesting the output of Cinegy Multiviewer over Wi-Fi or LTE, for a short confidence check of that output.

In listener mode, a device waits for a request to open an SRT connection. The listener device only needs to know that it should listen for SRT packets on a certain port. The URL of the receiver in listener mode, should not refer to any specific address as a source of SRT packets, for example:


In this case, the application receiving the stream will accept the first valid SRT streams sent to UDP port 9000. This allows a receiver to wait for a sending device to choose to send material to the input, allowing the receiver to wait in a configured state while the sender is set up or adjusted later. This is useful for defining the receiver that can retain a static configuration at runtime while senders are altered, for example allowing Cinegy Multiviewer to listen for incoming streams from a mobile device or uplinked studio.

If you want your SRT output stream to be encrypted, specify the SRT passphrase in the corresponding field.


Multicast Parameters


Here define the following parameters:

  • Primary source IP – select the IP address of the local network adapter that will be used for multicast output.

  • Backup source IP – select the IP address of the local network adapter that will be used for multicasting instead of the primary source IP.

    It is recommended to set up a static IP address for this adaptor. The "Primary source IP" and "Backup source IP" parameters affect multicast mode only.
  • TTL – here define the number of routers (hops) that multicast traffic is permitted to pass through before expiring on the network.

    The "TTL" parameter affects multicast mode only.
    Refer to this documentation for more information on the TTL option.

Video Format Options

Define the video format of the rendered output stream:

Refer to the System Recommendations article for full details about currently supported video formats.

Advanced Half-height Video Output

Using the TV formats from the "Half-height" section allows user to sub-divide the CPU and GPU loads between several servers:


In this case, the corresponding half-height aspect ratio should be chosen from the "Force aspect ratio" drop-down list in the Cinegy Multiviewer Layout Designer for the corresponding player.

Please refer to the What’s new in Cinegy Multiviewer 15 post for more information about advanced half-height video input and output.

Video Compression Options


Here define the following parameters:

  • Video encoder – choose from the pull-down list the video encoder.

    For the selected video stream you can also define its further parameters, such as bitrate, chroma subsampling type (4:2:0, 4:2:2), encoding method (Frame or Field), the length and type of the GOP sequence. For H.264 video stream the H.264 entropy coding mode setting is also available. The “Adaptive” option enabled allows GOP to be of variable length.

    The encoding method of ‘frame’ should be selected for progressive mode output, and 'field' for interlace. Please also note that when encoding with Cinegy Software H.264, I or IP encoding mode is recommended (B-frame encoding is not recommended).
  • Audio type – define the audio type with its associated bitrate for the selected video stream.

  • FEC – the parity packets generated for any stream which can be used to correct missing data due to packet loss; check this option and define the rows and columns values in the corresponding fields.

Output Registering

The "Register output" parameter affects multicast mode only.

The "Register output" option allows user to register the output stream in the Cinegy Route Directory Service in order to be used by other Cinegy software components as an RTP/UDP input. To be used, enable the corresponding option and define the following parameters:

  • Output ID – define the output stream ID (any unique text string).

    No special symbols can be used for the stream ID; alphanumeric only and spaces are allowed.
  • Registration server – enter the Cinegy Route IP via keyboard or browse for the corresponding registration server via the browse button.

Shared RAM Output Settings

Select the "RAM Output" option from the left hand section of the "Output settings" tab:


Define the following parameters for the Shared RAM output device:

  • TV format – choose the desired TV format from the drop-down list.

  • Output name – define the name for your output device.

  • Global namespace – check this option to enable sharing between several users on the machine, or between applications and services.

  • Audio channels – define the number of output audio channels.

NDI Output Settings

Select the "NDI Output" option from the left hand section of the "Output settings" tab:


Define the following parameters for the NDI output device:

  • Video format – choose the desired TV format.

  • Output name – define the name of the output NDI stream.

Output Layout

Cinegy Multiviewer offers an option to assign particular layout to the output.

This option is only available when "Designer layout" is selected as a layout type in input settings. The layout file previously created via Cinegy Layout Designer should be specified as a file template.

The layout file can contain several different designed layouts. If the "Layout" parameter is set to "Auto", layout switching using hot keys will result in changing to corresponding layout on the output. To assign the particular layout to be displayed on the output, select its number in the "Layout" drop-down list.

If in the layout file there is no layout with the corresponding index number, black frames will be generated on the output.
