Below is a snippet from man mkvmerge:
--display-dimensions TID:widthxheight
Matroska(TM) files contain two values that set the display
properties that a player should scale the image on playback
to: display width and display height. These values can be
set with this option, e.g. '1:640x480'.
Another way to specify the values is to use the
--aspect-ratio or the --aspect-ratio-factor option (see
below). These options are mutually exclusive.
--aspect-ratio TID:ratio|width/height
Matroska(TM) files contain two values that set the display
properties that a player should scale the image on playback
to: display width and display height. With this option
mkvmerge(1) will automatically calculate the display width
and display height based on the image's original width and
height and the aspect ratio given with this option. The
ratio can be given either as a floating point number ratio
or as a fraction 'width/height', e.g. '16/9'.
Another way to specify the values is to use the
--aspect-ratio-factor or --display-dimensions options (see
above and below). These options are mutually exclusive.
--aspect-ratio-factor TID:factor|n/d
Another way to set the aspect ratio is to specify a factor.
The original aspect ratio is first multiplied with this factor
and used as the target aspect ratio afterwards.
Another way to specify the values is to use the
--aspect-ratio or --display-dimensions options (see above).
These options are mutually exclusive.
