class Aws::MediaConvert::Types::Mp4Settings

These settings relate to your MP4 output container. You can create audio only outputs with this container. For more information, see docs.aws.amazon.com/mediaconvert/latest/ug/supported-codecs-containers-audio-only.html#output-codecs-and-containers-supported-for-audio-only.

@note When making an API call, you may pass Mp4Settings

data as a hash:

    {
      audio_duration: "DEFAULT_CODEC_DURATION", # accepts DEFAULT_CODEC_DURATION, MATCH_VIDEO_DURATION
      cslg_atom: "INCLUDE", # accepts INCLUDE, EXCLUDE
      ctts_version: 1,
      free_space_box: "INCLUDE", # accepts INCLUDE, EXCLUDE
      moov_placement: "PROGRESSIVE_DOWNLOAD", # accepts PROGRESSIVE_DOWNLOAD, NORMAL
      mp_4_major_brand: "__string",
    }

@!attribute [rw] audio_duration

Specify this setting only when your output will be consumed by a
downstream repackaging workflow that is sensitive to very small
duration differences between video and audio. For this situation,
choose Match video duration (MATCH\_VIDEO\_DURATION). In all other
cases, keep the default value, Default codec duration
(DEFAULT\_CODEC\_DURATION). When you choose Match video duration,
MediaConvert pads the output audio streams with silence or trims
them to ensure that the total duration of each audio stream is at
least as long as the total duration of the video stream. After
padding or trimming, the audio stream duration is no more than one
frame longer than the video stream. MediaConvert applies audio
padding or trimming only to the end of the last segment of the
output. For unsegmented outputs, MediaConvert adds padding only to
the end of the file. When you keep the default value, any minor
discrepancies between audio and video duration will depend on your
output audio codec.
@return [String]

@!attribute [rw] cslg_atom

When enabled, file composition times will start at zero, composition
times in the 'ctts' (composition time to sample) box for B-frames
will be negative, and a 'cslg' (composition shift least greatest)
box will be included per 14496-1 amendment 1. This improves
compatibility with Apple players and tools.
@return [String]

@!attribute [rw] ctts_version

Ignore this setting unless compliance to the CTTS box version
specification matters in your workflow. Specify a value of 1 to set
your CTTS box version to 1 and make your output compliant with the
specification. When you specify a value of 1, you must also set CSLG
atom (cslgAtom) to the value INCLUDE. Keep the default value 0 to
set your CTTS box version to 0. This can provide backward
compatibility for some players and packagers.
@return [Integer]

@!attribute [rw] free_space_box

Inserts a free-space box immediately after the moov box.
@return [String]

@!attribute [rw] moov_placement

If set to PROGRESSIVE\_DOWNLOAD, the MOOV atom is relocated to the
beginning of the archive as required for progressive downloading.
Otherwise it is placed normally at the end.
@return [String]

@!attribute [rw] mp_4_major_brand

Overrides the "Major Brand" field in the output file. Usually not
necessary to specify.
@return [String]
