Audio formats in input containers

Media Encoder Standard supports carrying the following audio formats in input containers:

  • MXF, GXF, and QuickTime files, which have audio tracks with interleaved stereo or 5.1 samples


  • MXF, GXF, and QuickTime files where the audio is carried as separate PCM tracks but the channel mapping (to stereo or 5.1) can be deduced from the file metadata

Support for explicit/user-supplied channel mapping will be provided in the near future.
