[Tex/LaTex] Change aspect ratio in beamer for a single frame

beamer

I have a presentation in 4:3, but would like to include a single slide from a 16:9 presentation made in beamer. These are complex slides, with subtle layout and animation, so I would prefer not to adapt the slide to 4:3. It is easier for me to admit that one slide will have a different aspect ratio. I was however not able to find any suggestions online, how to change aspectratio for a single frame.

This is one of the things I would like to understand in beamer, to increase my quest in making my beamer presentations more reusable. In Power Point it is relatively easy to glue presentations from existing fragments of other ones.

It is not difficult to change the page width if you don't care about layout elements like navigation symbols:

\documentclass{beamer}
\usepackage{lipsum}
\begin{document}
\begin{frame}
\lipsum[1]
\end{frame}


\setlength\pdfpagewidth{16.00cm}%
\setlength\pdfpageheight{9.00cm}%

\begin{frame}
blub
\pause
blub
\pause 

blub
\end{frame}

\setlength\pdfpagewidth{12.80cm}%
\setlength\pdfpageheight{9.60cm}%


\begin{frame}
blub
\pause

blub
\pause

blub
\end{frame}


\end{document}

The aspectratio option doesn't set any useful flag, apart from the page dimensions. One could check for these dimension pairs or else doing a direct check from the options list; here are two macros defined with the help of expl3 according to the latter strategy.

\documentclass[aspectratio=1610]{beamer}

\usepackage{xparse}
\ExplSyntaxOn
\NewDocumentCommand{\ifaspectratio}{mmm}
 {
  % Recover the option from those passed to the class
  \keys_set:nf { zunbeltz/beameroptions } { \use:c { opt@beamer.cls } }
  \str_if_eq:nVTF { #1 } \l_zunbeltz_aspectratio_tl { #2 } { #3 }
 }
\NewDocumentCommand{\xifaspectratio}{mO{}}
 {
  % Recover the option from those passed to the class
  \keys_set:nf { zunbeltz/beameroptions } { \use:c { opt@beamer.cls } }
  \str_case:Vnn \l_zunbeltz_aspectratio_tl { #1 } { #2 }
 }
% We need to define only one key, the other are treated as `unknown'
\keys_define:nn { zunbeltz/beameroptions }
 {
  aspectratio .tl_set:N = \l_zunbeltz_aspectratio_tl,
  aspectratio .initial:n = 43,
  unknown .code:n = {},
 }

% Generate the variants we need
\cs_generate_variant:Nn \keys_set:nn { nf }
\cs_generate_variant:Nn \str_if_eq:nnTF { nV }
\cs_generate_variant:Nn \str_case:nnn { V }
\ExplSyntaxOff

\begin{document}
\begin{frame}
\ifaspectratio{1610}{We're on 16:10}{We're not on 16:10}

\xifaspectratio{
  {169}{We're on 16:9}
  {43}{We're on 4:3}
}[None of the above]
\end{frame}
\end{document}

The macro \ifaspectratio takes three arguments, the ratio which we want to test, the true text and the false text.

The macro \xifaspectratio is more flexible: it takes one mandatory argument, which is a list of pairs {<ratio>}{<text>} and an optional argument for a "none of the above" case.

By adding to \keys_define:nn { zunbeltz/beameroptions } one could define similar macros for checking other options.

Maybe not the most elegant solution, but you can use pgfpages to place all your slides on one page:

\documentclass{beamer}
\usetheme{Boadilla}

\usepackage{pgfpages}
\pgfpagesuselayout{2 on 1}

\begin{document}

\begin{frame}
    \frametitle{Frame 1}
\end{frame} 

\begin{frame}
    \frametitle{Frame 2}
\end{frame}

\end{document}

This pdf can now either directly be directly or after conversion in a suitable format be used in the presentation tool of your choice. For example in Prezi on can directly add the pdf. For animating the presentation prezi frames can be added around the beamer frames and voilà:
