Removing an object (\institute{}) from Beamer title page

Question

I want to remove the \institute from the title page because I used it as \insertinstitute in \setbeamertemplate{footline} to customize footline{}. Apparently, non of the code below works. Many thanks in advance.

\setbeamertemplate{institute}{}
\setbeamertemplate{title page}[noinstitute]

Answer 1

You can redefine \institute locally:

\documentclass{beamer}

\title{Test}
\institute{My institute}

\begin{document}
{
  \institute{}
  \begin{frame}
    \maketitle % title page without institute
  \end{frame}
}

\begin{frame}
  \maketitle
\end{frame}

\end{document}
