Creating video ABR streaming outputs - MediaConvert

Creating video ABR streaming outputs

For each video output that you include in your output group, AWS Elemental MediaConvert creates one video rendition, or set of segmented video files. Multiple video renditions in a streaming package, of varying resolutions and video quality, allow the end viewer's device to adapt the quality of video to the available bandwidth.

Note

Although the job has only one video input selector, ABR streaming output groups often have several video outputs per output group.

To create and set up video ABR streaming outputs

  1. On the Create job page, in the Job pane on the left, under Output Groups, below the CMAF, Apple HLS, DASH ISO, or Microsoft Smooth Streaming output group that you want add outputs to, choose Output 1.

    When you create an output group, AWS Elemental MediaConvert automatically populates the output group with output 1, so you don't need to explicitly create the first output.

  2. In the Output settings pane, for Name modifier, enter a value.

    AWS Elemental MediaConvert appends the name modifier to the file names that it assigns to the files that it creates for this output. Enter a name modifier that will make it easy to identify which files came from which output, such as -video-hi-res.

  3. If one of the predefined groups of settings listed under Preset is suitable for your workflow, choose it from the list. If you use a preset, skip the next step of this procedure.

  4. Specify your video settings as follows:

    1. In the Output settings section, specify values for any remaining general settings. Depending on the output group type, these settings might include transport stream settings or other container settings. For more information about individual settings, choose the Info link next to each setting.

    2. In the Stream settings section, specify values for video encoding. The video settings are selected by default, so you don't need to explicitly choose this group of settings. For more information about individual settings, choose the Info link next to each setting.

      Note

      There is only one input video selector per job, so you don't need to explicitly choose it when you set up your video outputs.

    For more information about individual settings, choose the Info links on the console.

  5. If your output includes a group of audio settings by default, delete it as follows:

    1. In the Stream settings section, choose Audio 1.

    2. Choose Remove audio.

  6. If you want multiple video renditions in your ABR streaming package, repeat the preceding steps of this procedure to create an additional video output for each one.
