profile property

String? profile
final

You can only choose an audio profile when you specify AAC for the value of Audio:Codec.

Specify the AAC profile for the output file. Elastic Transcoder supports the following profiles:

  • auto: If you specify auto, Elastic Transcoder selects the profile based on the bit rate selected for the output file.
  • AAC-LC: The most common AAC profile. Use for bit rates larger than 64 kbps.
  • HE-AAC: Not supported on some older players and devices. Use for bit rates between 40 and 80 kbps.
  • HE-AACv2: Not supported on some players and devices. Use for bit rates less than 48 kbps.
All outputs in a Smooth playlist must have the same value for Profile.
