[Tex/LaTex] How to edit the title page of the beamer

Question

I would like to edit the title page of the beamer presentation template in order display my name and my project supervisor's name in the title slide. Is this possible? Can it be achieved easily?

Thanks in advance

Answer 1

One possible solution follows. I adjusted some settings so that now you have a new command \supervisor which behaves analogously to \author and lets you introduce the supervisor's name below the author's name. The name will be preceded by the string "Supervisor: " which can be changed using \supervisortitle.

\documentclass{beamer}
\usetheme{CambridgeUS}

\makeatletter
\let\insertsupervisor\relax
\newcommand\supervisortitle{Supervisor}
\mode<all>
{
  \newcommand\supervisor[1]{\def\insertsupervisor{#1}}
  \titlegraphic{}
}
\defbeamertemplate*{title page}{supdefault}[1][]
{
  \vbox{}
  \vfill
  \begingroup
    \centering
    \begin{beamercolorbox}[sep=8pt,center,#1]{title}
      \usebeamerfont{title}\inserttitle\par%
      \ifx\insertsubtitle\@empty\relax%
      \else%
        \vskip0.25em%
        {\usebeamerfont{subtitle}\usebeamercolor[fg]{subtitle}\insertsubtitle\par}%
      \fi%     
    \end{beamercolorbox}%
    \vskip1em\par
    \begin{beamercolorbox}[sep=8pt,center,#1]{author}
      \usebeamerfont{author}\insertauthor
    \end{beamercolorbox}
    \ifx\insertsupervisor\relax\relax\else
    \begin{beamercolorbox}[sep=8pt,center,#1]{author}
      \usebeamerfont{author}\supervisortitle:~\insertsupervisor
    \end{beamercolorbox}\fi
    \begin{beamercolorbox}[sep=8pt,center,#1]{institute}
      \usebeamerfont{institute}\insertinstitute
    \end{beamercolorbox}
    \begin{beamercolorbox}[sep=8pt,center,#1]{date}
      \usebeamerfont{date}\insertdate
    \end{beamercolorbox}\vskip0.5em
    {\usebeamercolor[fg]{titlegraphic}\inserttitlegraphic\par}
