SCTE-35 limitations - MediaConvert

SCTE-35 limitations

Limitations to SCTE-35 support are as follows:

  • You can either specify insertion points using ESAM XML or pass through SCTE-35 messages from the input. You can't do both.

  • AWS Elemental MediaConvert supports only time_signal messages, not splice_insert messages.

  • The service inserts SCTE-35 messages only into the following outputs:

    • Outputs in File group output groups with MPEG-2 Transport Stream set for Container.

      Set the container for each output under Output settings, Container.

    • Outputs in DASH ISO output groups.

    • Outputs in Apple HLS output groups.

    • Outputs in CMAF output groups.

  • The service forces Instantaneous Decoder Refresh (IDR) frames at the insertion points specified in your ESAM XML document for the following output codecs: MPEG-2, MPEG-4 AVC (H.264), or HEVC (H.265).

    In the MediaConvert console, go to Encoding settings, Video, and then set the codec for each output in the Video codec section.

  • DASH ISO and CMAF DASH output groups only support single-period manifest outputs.
