[Tex/LaTex] The \titlepage problem in beamer

beamertitles

When I put in the preamble. It has several warning as

Token not allowed in a PDF string (Unicode)

Because I use the $^1$ in the title.

Then when I put in the document. the warning appears. How do I solve it? Thanks

Option `pdfauthor' has already been used

My MWE

\documentclass[presentation]{beamer}
\let\Tiny\tiny
\usepackage{hyperref}
\usetheme{Berkeley}
\begin{document}

\renewcommand{\thefootnote}{$\aleph$}


\title[Cross]{\large Experimental Studies %
\thanks{\scriptsize Project supported by foundation:  Supported by the National Nature Science Foundation}}
\author[A,B,C]{A$^1$,
B$^1$
and C$^2$}
\institute[Fluid Mechanics]{$^1$Department of Mechanics \& Engineering Science\\
$^2$College of Science}
\date[The second presentation, 2013]{The second presentation, 2013}
%\logo{\includegraphics[height=16pt]{picture/Fudanlog.PNG}}
\date[\initclock\tdtime]{\today}

\begin{frame}
\titlepage
\end{frame}

\section{A section}
\subsection{A subsection}
\begin{frame}
  \frametitle{Frame title1}
  \framesubtitle{frame subtitle1}
  Some text s
\end{frame}
\end{document}

You can use the \inst{number} command within beamer to indicate the institution an author comes frome instead of using mathematical superscripts.

\documentclass[presentation]{beamer}
\let\Tiny\tiny
\usepackage{hyperref}
\usetheme{Berkeley}
\begin{document}

\renewcommand{\thefootnote}{$\aleph$}


\title[Cross]{\large Experimental Studies %
\thanks{\scriptsize Project supported by foundation:  Supported by the National Nature Science Foundation}}
\author[A,B,C]{A\inst{1}  \and B\inst{2}  \and C\inst{2}}

% Old style
%\author[A,B,C]{A$^1$,
%B$^1$
%and C$^2$}
\institute[Fluid Mechanics]{$^1$Department of Mechanics \& Engineering Science\\
$^2$College of Science}
\date[The second presentation, 2013]{The second presentation, 2013}
%\logo{\includegraphics[height=16pt]{picture/Fudanlog.PNG}}
\date[\initclock\tdtime]{\today}

\begin{frame}
\titlepage
\end{frame}

\section{A section}
\subsection{A subsection}
\begin{frame}
  \frametitle{Frame title1}
  \framesubtitle{frame subtitle1}

\end{document}

You could use \only inside \title:

\documentclass{beamer}
\mode<presentation>
{
  \usetheme{Madrid}
}

\title[]{\only<1>{Title A}\only<2>{Title B}}

\begin{document}
  \begin{frame}
    \titlepage
    %some logos etc. 
  \end{frame}
\end{document}

EDIT: here's a modified version when the titles have different length and have different heights; all the code between \makeatletter and \makeatother was written by Martin Scharrer in his answer to Beamer alt command like visible instead of like only (all the credit goes to him and to Matthew Leingang for pointing this out to me). The only modification I added was a new command to use \parboxes and to allow different vertical alignment for the titles.

\documentclass{beamer}
\mode<presentation>
{
  \usetheme{Madrid}
}

\newcommand\math@@Alt[3]{%

[Tex/LaTex] How to customize \titlepage in beamer

You could use \defbeamertemplate to define your own title page template. There you may use the commands \inserttitle, \insertauthor, \insertdate etc. to insert those values, also don't forget to use the predefined font and color values.

Here is a compilable example. Of course you can use \centering, \vfill, beamercolorbox etc. but I keep it simple for the purpose of demonstration.

\documentclass{beamer}
\defbeamertemplate*{title page}{customized}[1][]
{
  \usebeamerfont{title}\inserttitle\par
  \usebeamerfont{subtitle}\usebeamercolor[fg]{subtitle}\insertsubtitle\par
  \bigskip
  \usebeamerfont{author}\insertauthor\par
  \usebeamerfont{institute}\insertinstitute\par
  \usebeamerfont{date}\insertdate\par
  \usebeamercolor[fg]{titlegraphic}\inserttitlegraphic
}
\title{A customized title page}
\subtitle{for demonstration}
\author{Stefan Kottwitz}
\date{\today}
\begin{document}
\maketitle
\end{document}

customized title page
