Once you have created the profile, you can use it to transcode an input stream.
To Transcode an Input Stream:
- On the Inputs page of ZiXi Broadcaster, click the desired row of the incoming stream that you want to transcode.
- Click the
button on the right end of the selected row and then Transcode. The Transcode <input stream name> window with the settings of the selected input stream is displayed. 
- Enter the unique Stream I.D. for the new transcoded input 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 is created and appears in an embedded window labeled Transcoded sources under the original input stream from which it was created.
Parameter | Description |
|---|---|
| Advanced Options | |
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 | |
| 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 |
