\subsection{Pimping your slides}

\begin{frame}
  {And even more good news}
  {\ldots almost seems to good to be true\ldots}
  \small
  However, now you can pimp your slides like never before. You can incorporate:
  \begin{itemize}
  \item videos and audio fragments
  \item animated GIFs and LaTeX animations
  \item iframe content
  \end{itemize}
  without being tied to Acrobat reader.
  In addition, there are some extra features
  \begin{itemize}
  \item press '?' for keyboard help, amongst which you will find:
  \item press 'm' to open the slide menu on the left
  \item press 'o' to get an overview of the slides
  \item press 's' to start a speaker view
  \item press 'g' to go to a specific slide by typing its slide number
  \end{itemize}
  The pancake menu on the bottom left also opens the menu.

\note{
  Don't spend too much time on this slide
}

\section{In detail}

\subsection{Candy for the eye}

\begin{frame}
  {Placing videos}
  {}
  \only<1>{On this first slide there is nothing to see. On the next animation frame, a video will appear.}
  \only<2>{Here it is!}
  \video<2>[above,draw,autoplay,height=0.7,aspectratio=16/9,
            background=yellow,fit=contain]
  (myvid) \at (0.5,0.1) {Media/beamer-reveal-testvideo.mp4}
  \tikz[remember picture,overlay] \node<2>[anchor=north,font=\tiny] at (myvid.south)
       {An example video (C) Walter Daems};
\end{frame}

\begin{frame}
  {Placing images (possibly animated)}
  {}
  \begin{columns}
    \column[T]{0.45\textwidth}
    Below you will find a png (for which you don't need reveal, BTW).
    \vspace*{1cm}

    Of course, you can exploit the transparency of the background layer in the PNG!
    \vspace*{2cm}

    And on the top right you will find a swinging pendulum (an animated GIF).
    \column[T]{0.45\textwidth}
    % this is a image whose box consumes area on your slide
    \image[width=0.33,aspectratio=1,fit=contain,draw] (myimage) {Media/beamer-reveal-AnimatedPendulum.gif}
  \end{columns}
  % this is an overlayed image (not consuming any space)
  \image[width=0.25,aspectratio=1,fit=contain] \at (0.1,0.6) {Media/beamer-reveal-WiresTp.png}
  \image[width=0.1,aspectratio=1,fit=contain] \at (0.9,0.1) {https://www.digmanwaves.net/About/Pictures/WalterDaems.jpg}
\end{frame}

\begin{frame}
  {Placing iframe material (possibly animated)}
  {e.g. generated with asymptote}

  Click and drag on the iframe below. You can manipulate it! Use your mouse
  scroll-wheel to zoom in or out.
  \iframe[draw,anchor=north,height=0.6,aspectratio=16/9,embed,
          fit=cover] \at (0.5,0.7) {Media/beamer-reveal-PCB.html}
\end{frame}

\note{
  Don't mention the amount of hours that went into this iframe!

\subsection{Resonance for the ear}

\begin{frame}
  {Adding audio to your slides}
  {}
  Below, there is an audio block
  that automatically starts playing.\\
  \audio[autoplay,controls,width=0.1,aspectratio=16/9,
    background=blue,fit=cover] {Media/beamer-reveal-AudioSample.ogg}
\end{frame}
