The "Playback" tab allows defining player mode, as well as configuring channels and devices:
Use the "Player mode" drop-down list to define the basic TV format system used for the Cinegy Playout server broadcasting:
Changing player mode settings will reset the I/O and proxy settings to defaults:
It is possible to add HD or UHD clips to SD playlists or UHD clips to HD playlists. For example, to be able to add 1920x1080i 25 Hz video files to the playlist of the 720x576i 25 Hz video format, do the following:
Choose the appropriate video system in the Cinegy Air Configurator.
Choose the "1920x1080 25Hz" option in the "Player mode" drop-down list.
Double-click a channel or press the "Change" button and choose the appropriate (720x576i 25Hz 16:9) channel video format in the dialog that appears. Pressing the "Finish" button will apply the changes:
Use the drop-down list to select the required bit depth for stream processing among the options represented in the drop-down list:
Selecting the "RGBA 8-bit" option from the drop-down list will set up the Key&Fill mode.
Multiple channels can be added to enable broadcasting of the same playlist to several channels of different TV formats simultaneously.
To add another channel to the list of channels used for broadcasting, press the "Add channel…" button. The following dialog box appears:
|The list of available TV formats may vary depending on chosen player mode.
Here choose the video format for the channel being added.
The following illustration shows the playback configuration with the four channels set:
|The bold font is used to indicate the master input and output devices as well as the primary TV format (channel).
The following diagram shows the general structure of playback performance:
Live input device can only be configured for the primary TV format (channel):
To set the input device, click "Input" device and press the "Add device…" button. The following dialog box appears:
Select one of devices and press the "Next" button.
The following input devices are available:
|Further configuration for each device is described in the Input Device Settings article.
The 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.
|The output device connected with the hardware and master clock (e.g. SDI, DirectShow, RTP, etc.) is recommended to be used as master.
To add the output device for the selected channel, press the "Add device…" button. The following dialog box appears:
The following output devices are available:
|It is possible to add several output devices. In this case, the playback will be performed to all the assigned devices simultaneously.
|Further configuration for each device is described in the Output Device Settings article.
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.
To delete a channel (except the first one) or an output device, select the required one and press the "Delete" button.
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.
The configuration of output devices is described here
|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 and Cinegy Title templates, as well as to decode files and streams if it is supported by a video card. The section contains the list of all installed graphics cards and allows selecting video effects accelerator card capable of processing real-time graphics from the drop-down list:
Therefore, the effects rendering can be performed on different cards. If the topmost "CPU" option is selected from the drop-down list, the effects rendering is performed on the CPU with equally allocated load.
If the selected graphics card does not support video effects acceleration, the "CPU" option will be applied automatically.
|Refer to this article within Cinegy Desktop Manual for details on working with video effects.
Defines the maximum video buffer size on the playout server. The default value for all formats is 150. For high-resolution content (4K, 8K) it makes sense to reduce the default queue size to those more appropriate for GPU RAM (e.g. 25).
Drop Frame Timecode
Check the "Drop frame timecode" option to enable the NTSC time compensated mode.
Playout Engine generates SRT stream for the playout preview in the Cinegy Air control application as well as for Cinegy Playout Dashboard. To define the feedback codec to be used for this preview stream, select the desired one from drop-down list:
At the same time, the SRT feedback stream can be viewed in another SRT-supporting application, if it is installed on the machine with Cinegy Encode or Cinegy Playout Engine on board, such as VLC player or Cinegy Multiviewer. Define the SRT URL address as follows:
StreamIP – defines the IP address of the machine transmitting the SRT stream;
Port – should be set to 5421+N for main preview or 5471+N for cued preview; where N is the zero-based Playout engine instance number.
Key&Fill Mode (via RGBA Output)
Cinegy Playout can be set up to work in 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:
In this configuration Cinegy Playout generates the full frame from the Cinegy Title 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:
To set up Key&Fill mode, do not specify the input device in the "Playback" tab and select the "RGBA 8-bit" option from the drop-down list as it is shown below:
This will switch the video board to the RGBA 8-bit mode and the card will output two SDI signals (Key and Fill) using "Output A" and "Output B" BNC connectors.
|For the list of supported SDI cards in Key&Fill mode, please refer to Cinegy Air System Recommendations.
