Comment (by MasterQuestionable):

 ͏    I mean the necessity of their existence.\\
 ͏    Similar are just post-filters essentially applied on decoding.
 (comparable to [https://ffmpeg.org/ffmpeg-filters.html#Filtergraph-syntax
 ͏"-vf"])

 ͏    "... , what is hard is to have metadata that says how to extract
 sound and where does this sound move."\\
 <!^>    "how to extract sound": ?\\
 ͏    "where does this sound move": probably not metadata, but actual sound
 data.\\
 ͏    .\\
 ͏    IAMF much means how to transform sound data for representation under
 different contexts:\\
 ͏    Somewhat similar to the previous "The very White could never be the
 very White" predicament.\\
 \\
 \\
 ͏    All current container formats are sort of the similar problem:\\
 ͏    Unjustifiable complexity and bad primitives.\\
 ͏    .\\
 ͏    Designers probably did not well understand in advance: what video
 really is.

 ͏    See also: https://github.com/MasterInQuestion/talk/discussions/3

 ͏    Note:\\
 ͏    Try the
 [https://github.com/exiftool/exiftool/issues/260#issue-2254044650
 `exiftool`] command in [/attachment/ticket/11002/Extra.txt ͏"Extra.txt"]
 on "00006.MTS".\\
 ͏    And just see how many thoughtless things: so thoughtlessly piled-up
 the whole thing...
