[FFmpeg-user] What does ffmpeg consider metadata?

[Mark Filipak]

To me, metadata is such MPEG settings as 'progressive_sequence', 
'top_field_first', 'frame_pred_frame_dct', 'concealment_motion_vectors', 
'q_scale_type',
'intra_vlc_format', 'alternate_scan', 'repeat_first_field', 
'chroma_420_type', 'progressive_frame'.

What does ffmpeg consider metadata? I ask because this command:
'ffmpeg -i I:\VIDEO_TS\VTS_02_1.VOB -f D:\FOO'
resulted solely in this (from D:\FOO):
   ";FFMETADATA1
    encoder=Lavf58.31.104 "

Do I need to add a couple hundred more arguments? What would they be?
Note: ffmpeg documentation was no help.

Regards,
Mark.
