In the Beamer class, is it possible to change the height of a page and frame? I'm producing a document for web display and would like it to be on a continuously scrolling format so I would like to have frames with height 4 times taller than the current default height. I tried something like the MWE below but I get "Missing \begin{document} error"...
\documentclass{beamer}
\usepackage[papersize={12cm,30cm}]{geometry}
\begin{document}
\begin{frame}{test}
\end{frame}{test}
\end{frame}
\end{document}
beamerarticle
etc.
