I am using \columns in beamer to show two pictures. After I added \footnote{ExampleText} after captions, the ExampleTest just appear in each column. Now I want to show all of the ExampleText in the bottom of the slide instead of each column, how can I do this?

MWE:

\documentclass{beamer}
\usepackage{graphicx}
\begin{document}
 \begin{frame}
\begin{columns}
\begin{column}{.5\textwidth}
\includegraphics{img1}\footnote{f2}
\end{column}
\begin{column}{.5\textwidth}
\includegraphics{img2}\footnote{f1}
\end{column} 
\end{columns}
\end{frame}
\end{document}

You can use \footnotemark, \footnotetext{<text>}; a little example:

\documentclass{beamer}

\begin{document}

\begin{frame}
\begin{columns}
\column{.5\textwidth}
Some text for the first column and a test footnote\footnotemark
\column{.5\textwidth}
Some text for the second column and a test footnote\footnotemark
\end{columns}
\footnotetext[1]{A test footnote in the first column}
\footnotetext[2]{A test footnote in the second column}
\end{frame}

\end{document}

enter image description here

In a comment it has been asked how to use the same footnote text for two footnotes, one in each column; here's a possibility:

\documentclass{beamer}

\begin{document}

\begin{frame}
\begin{columns}
\column{.5\textwidth}
Some text for the first column and a test footnote\footnotemark
\column{.5\textwidth}
Some text for the second column and a test footnote\footnotemark[1]
\end{columns}
\footnotetext{A test footnote for both columns}
\end{frame}

\end{document}

enter image description here

  • Is there a way to have the footnotes appear at the same time as the item they belong to? Maybe something like \only<3-> to have the footnote appearing with the third item on the slide, but not before? – Matthias Braun Sep 19 '19 at 8:30

    @MatthiasBraun You can have \footnote<.->{Some text} and \footnote<3->{Some text} etc. – jadelord Sep 19 '19 at 13:55
  • To avoid to update footnote numbers by hand one can add at the beginning of the slides the code \newcounter{savedfootnotenumber} \setcounter{savedfootnotenumber}{\number\value{footnote}} and then \addtocounter{savedfootnotenumber}{1}\footnotetext[\value{savedfootnotenumber}]{First note}\addtocounter{savedfootnotenumber}{1}\footnotetext[\value{savedfootnotenumber}]{Second note} – Pietro C Sep 27 '19 at 8:11

The most consistent way to do this is to keep the footnotes as they are but supply the [frame] option to them.

\documentclass{beamer}

\begin{document}

\begin{frame}
\begin{columns}
\column{.5\textwidth}
Some text for the first column and a test footnote\footnote[frame]{A test footnote in the first column}
\column{.5\textwidth}
Some text for the second column and a test footnote\footnote[frame]{A test footnote in the second column}
\end{columns}
\end{frame}

\end{document}

Output as intended with standard footnote syntax

    In order to prevent the long footnote from overlapping the menu icons, you can add double back slash before the closing } – aiag Jan 2 '18 at 1:14
  • Is it possible to use something like \renewcommand<>{\footnote} ... to make this the default? I am using pandoc and the only way (as I see it) to enforce this is to redefine footnote command in the preamble. – jadelord Sep 19 '19 at 13:57

At first I removed this answer because I wasn't sure what you wanted. You might want to change the MWE above, I don't know. Anyway, this works for me to give a single footnote. Just call the footnote after explicitly closing the columns.

\documentclass{beamer}
\usepackage{graphicx}
\begin{document}
\begin{frame}
\begin{columns}
  \begin{column}{.5\textwidth}
  \includegraphics{img1}
  \end{column}
  \begin{column}{.5\textwidth}
  \includegraphics{img2}
  \end{column}
\end{columns}
*\footnote{Your footnote text.}
\end{frame}
\end{document}

Works for me. What did I miss?
