To Transcode an Input Stream:
- On the the Inputs page page of ZiXi Broadcaster, click the desired row of the incoming stream that you want to transcode.
- Click the
button button on the right end of the selected row and then then Transcode. The The Transcode <input stream name> window window with the settings of the selected input stream is displayed. 
- Enter the unique unique Stream I.D. for the new transcoded input stream.
- Under 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 select Keep original stream. In this case the video or audio input will not be transcoded. Click OK. 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 labeled Transcoded sources under under the original input stream from which it was created.
