Many apologies.  I didn't think an MWE was required to address the
question.  See below and also attached.  Run with:

$ lilypond --png -dresolution=300 mwe.ly

and 'flip' through the resulting pngs.

There are two commented lines in the \paper block.  One to annotate the
spacing, the other to line up the middle staff line to the centre of
the page.

\header {
    tagline = ##f
}

music = {
  \relative c'' \repeat unfold 3 {
    c4 c c c \break
  }
}

\score {
    \new Staff \music
    \layout { }
}

#(set! paper-alist (cons '("vid-line" .
    (cons (* 90 mm) (* 26 mm))) paper-alist))

\paper {
    #(set-paper-size "vid-line")
    print-page-number = ##f
    indent = 0.0
    short-indent = 0.0
%    top-system-spacing.basic-distance = #6
    top-margin = 0.0
    bottom-margin = 0.0
%    annotate-spacing = ##t 
}


#(set! toplevel-music-functions (cons unfoldRepeats toplevel-music-functions))

\header {
    tagline = ##f
}

music = {
  \relative c'' \repeat volta 3 {
    c4 c c c \break
  }
}

\score {
    \new Staff \music
    \layout { }
    \midi { }
}

#(set! paper-alist (cons '("vid-line" .
    (cons (* 90 mm) (* 26 mm))) paper-alist))

\paper {
    #(set-paper-size "vid-line")
    print-page-number = ##f
    indent = 0.0
    short-indent = 0.0
    top-system-spacing.basic-distance = #6
    top-margin = 0.0
    bottom-margin = 0.0
    annotate-spacing = ##t 
}
