Adding notes to beamer slide when using “\pause”

Question

I know how to add personal notes to slides thanks to this answer

But, when I use \pause inside the frame, it duplicates the note, like in this example:

%\documentclass[notes]{beamer}       % print frame + notes
\documentclass[notes=only]{beamer}   % only notes
%\documentclass{beamer}              % only frames

\begin{document}

\begin{frame}
\begin{itemize}
    \item talk about sth
    \pause
    \item talk about other thing
\end{itemize}

\note{talk about sth more}

\end{frame}  

\end{document}

I want it to output only one note for that frame, how can I do that?

Answer 1

You can specify that the note should only be shown for the first overlay using \note<1>{...}

You should not use the notes=only class option, it is obsolete and beamer will tell you this with a warning.

\documentclass{beamer}  

\setbeameroption{show only notes}

\begin{document}

\begin{frame}
\begin{itemize}
    \item talk about sth
    \pause
    \item talk about other thing
\end{itemize}

\note<1>{talk about sth more}

\end{frame}  

\end{document}
