Instead of manually selecting input streams to be transcoded, you can define templates with rules for automatic transcoding of input streams according to the settings of a pre-defined Transcoding Template. Every time a new input stream, which matches the conditions of the template, is added, it will be automatically transcoded into the transcoded streams defined in the template's settings. The input streams are identified by system according to naming patterns.

Note

The transcoding profiles used in the transcoding templates have to be created in advance (for more information see: Creating New Profiles).

To create a new transcoding template:

Click the Inputs tab at the top of the ZiXi Broadcaster administrative screen.
In the Menu bar, click the Templates () button.
The Transcoding Templates window is displayed:
Click New to define a new template.
The following window is displayed:
In the Input ID pattern field, enter a pattern for the Stream ID of the input stream that will be automatically transcoded. This pattern will be used to identify the input stream and can include variables that are marked with the "$" sign followed by a number (e.g. $1, $2, etc.) and/or with an asterisk "*" wildcard . The patterns should also include a part of the string that requires an exact match. For example, the pattern "$1_stream_$2kbps" will match an input stream "talk_show_stream_600kbps".
Click Apply.
The new template is added to the list of transcoding templates. However the transcoding will not be active until you define trancoded stream rules.
Select the newly created template and click the button, located at the right-hand corner to define a transcoded stream rule.
The Transcode <template_name> window opens:
Enter the unique Stream I.D. for the transcoded stream.
In the Max Outputs field, define the maximal number of outputs that can be connected to the stream.
Under Stream Parameters, select the desired Video Profile and/or Audio Profile that you have configured. If you have not configured a video or audio profile you can select Keep original stream. In this case the video or audio input will not be transcoded. You can also set specific transcoding parameters for the specific stream (see table below for more details).

Click OK.
The transcoded input stream rule is created and appears as follows:

If an input stream enters Zixi Broadcaster and matches the Input ID pattern, it will be transcoded according to all the transcoded input stream rules that were created.

Parameter	Description
Video Profile	Select an existing profile or select Keep original stream if you do not wish to transcode the video stream.
Audio Profile	Select an existing profile or select Keep original stream if you do not wish to transcode the audio stream.
Transport Stream Bitrate (Kbps)	Specifies the bitrate of the transport stream. This parameter is optional. If you do not specify a TS Bitrate, the stream will be VBR. If you specify a bitrate, the stream will be CBR.
Use Hardware Acceleration (if available)	Select this checkbox to use an existing hardware acceleration component.
Pass all PIDs	Select this checkbox to pass-through all non-transcoded PIDs.
Enable time shift	Select to enable delayed transmission.
Maximum delay [hh:mm:ss]	Specify the time of the delayed transmission of this stream. Maximum: 24 hours.
Transmit as multicast	Selecting this checkbox enables the transmission of this stream’s outputs as multicast. A ZiXi receiver that will pull the stream will receive it in multicast. By default ZiXi Broadcaster is configured to allow transparent fallback to unicast if it is out of the LAN. Requires enabling Multicast Pull in the Settings. This setting requires enabling Multicast Pool (Settings > Multicast Pool).
Multicast Only	Selecting this checkbox will force the transmission of this stream only in multicast.
Recording Parameters
Max recorded file duration [hours]	Specifies the maximum time allotted for recording a video stream. Default: 2 hours
Keep recorded files for [hours]	Specifies the maximum time for storing the recording. Default: 0 hours

Repeat steps 6-10 above to create additional transcoded input stream rules.
