[mrfragger]

mpv if you use the buiiltin screenshot it doesn't match exactly the alignment. So best to use built-in screenshot for OS.

Ctrl+t cycle-values sub-line-spacing '-110' '-90' '-70' '-50' '-30' '-25' '-20' '-15' '-10' '-5' '0'  #! [Subtitles] > [Format] > Sub Line Spacing
-  cycle-values sub-align-x  'left' 'center' 'right'  #! [Subtitles] > [Format] > Subtitle left, center, right
=  cycle-values sub-justify  'left' 'center' 'right' 'auto'  #! [Subtitles] > [Format] > Subtitle justify left, center, right, auto
_  cycle-values sub-align-y  'bottom' 'center' 'top'  #! [Subtitles] > [Format] > Subtitle align-y bottom, center, top
Alt+t cycle-values sub-margin-x '19' '50' '100' '150' '200' '250' '300'  #! [Subtitles] > [Format] > Subtitle margin-x

Use the above for formatting subs and moving them around.
