Info

For downstream satellite workflows, you will probably need to generate constant bitrate (CBR) streams. This setting is configured at the individual input level (not the transcoding profile level). To set a CBR, enter the desired Transport Stream Bitrate (Kbps) as described in the Transcoding Broadcaster Input Streams section.


To Create a New Profile:

  1. In the Transcoder page, click .
    The Add New Profile window is displayed:
  2. Select the desired Codec type - MPEG2, H.264 or H.265 for a video profile or select AAC or Opus for an audio profile.
  3. Enter the desired fields in the Profile configuration (see table below for additional parameters). Select a specific Preset profile to automatically fill in the default settings for that profile, OR select Custom to create a new profile from scratch.

    Info

    You can edit specific fields of a preset configuration while creating the profile.


  4. If you want to configure the Advanced options for the video profiles, select Advanced options and fill in the respective fields (see table below for additional parameters).
