Output Device

Cinegy Playout instance can run in simulcast mode having dedicated output devices for each TV format (channel). Thus each channel can be configured to have multiple output devices used for simultaneous broadcasting.

Tip
The output device connected with the hardware and master clock (e.g. SDI, DirectShow, RTP, etc.) is recommended to be used as master.

The following illustration shows the playback configuration with the four channels set:

Channels_list_configured
Note
The bold font is used to indicate the master output device.
Note
The list of available TV formats may vary depending on the chosen player mode.

Add_device_dialog

The following output devices are available:

Note
It is possible to add several output devices. In this case, the playback will be performed to all the assigned devices simultaneously.
Important

Change_button

To change the channel or device configuration, choose the required item and press the "Change…​" button. Make your changes in the configuration box that appears.

Delete_button

To delete a channel (except the first one) or an output device, select the required one and press the "Delete" button.

It is possible to add HD or UHD clips to SD playlists or UHD clips into HD playlists. For example, to be able to add 1920x1080i 29.97 Hz video files to the playlist of the 720x480i 29.97 Hz video format, do the following:

  1. Choose the appropriate video system in Cinegy Air Configurator.

  2. Choose the "1920x1080 29.97Hz" option in the "Player mode" drop-down list.

  3. Double-click a channel or press the "Change" button and choose the appropriate (720x480i 29.97Hz 16:9) channel video format in the dialog that appears.

Clean Output

A clean output is considered to be the channel output that does not have any secondary events, logos and graphics originally added to it. Selecting "Clean Output" will generate clean feed output not affected by graphics or text.

clean_output

The configuration of output devices is described here

Note
Please note that the clean output option is licensed. To use the clean output functionality make sure Clean Engine Output license is present.

Video Effects Accelerator

Video Effects Accelerator defines the GPU board to be used to render video effects in Cinegy Desktop items. The section contains the list of all installed graphics cards and allows to select video effects accelerator card capable of processing real-time graphics from the drop-down list:

effects_accelerator

Therefore, the effects rendering can be performed on different cards. If the "Default CPU" option is selected from the drop down-list, the effects rendering is performed on the CPU with equally allocated load.

If the selected graphic card does not support video effects acceleration, the "Default CPU" option will be applied automatically.

Important
Refer to Working with Effects paragraph within Cinegy Desktop Manual for details on handling video effects.

Queue Size

Defines the maximum video buffer size on the playout server. The default and recommended value for all formats is 150.

Drop Frame Timecode

Check the "Drop Frame timecode" option to enable the NTSC time compensated mode.

Feedback Codec

Playout Engine generates RTP stream for the playout preview in the Cinegy Air control application as well as for the Cinegy Playout Dashboard. To define the feedback codec to be used for this preview stream, select the desired one from drop-down list:

feedback_codec

Key&Fill Mode (via RGBA Output)

Cinegy Playout can be set up to work in the Key&Fill mode allowing to superimpose titles or graphics over the video source using the video mixer upstream or downstream keyers.

The typical scenario using the Key&Fill mode is shown on the diagram below:

Key&Fill_scheme

In this configuration Cinegy Playout generates the full frame from the Cinegy Titler template, but on the transparent background, containing only the template objects on the output.

Then the external video mixer keyes this frame into the live video signal:

Video_Mixer

To set up the Key&Fill mode, do not specify the input device on the "Playback" tab and select the "RGBA Output" option. This will switch the video board to the RGBA 32bit mode and the card will output two SDI signal (Key and Fill) using "Output A" and "Output B" BNC connectors.

Hardware Requirements

Important
For the list of supported SDI cards in Key&Fill mode, please refer to Cinegy Air System Recommendations.
