The transcoder comes with pre-set common video profiles:

In order to transcode an input stream from the Inputs screen you must first configure the transcoding profiles in the Transcoder screen. For more information, see Transcoder section below. 

To Transcode an Input Stream:

  1. In the Zixi Broadcaster Inputs page, click the desired incoming stream that you want to transcode.
  2. Click  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.
  3. Enter the unique Stream I.D., which will correspond to the new transcoded input that will be added.
  4. Under Stream Parameters, select the desired Video Profile and the desired Audio Profile. 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.   
  5. 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.
