+\begin{center}
+  \href{run:ID16A.mp4?autostart&loop}{\includegraphics[height=0.23\textheight]{ID16A_snap}}
+\end{center}
+\begin{itemize}
+  \item This may or may not work on Windows machines, but tested to work on Linux.
+  \item This requires a supporting presenter, \emph{e.g.} \textbf{pdfpc}.
+  \item Also, at least the ``base'', ``good'', ``bad'', and ``libav'' GStreamer plug-ins should be installed.
+  \item The video file should be in the defined path (it is not embedded into the presentation, but linked to it).
+  \item If for any reason the video will not play, the embedded image will be displayed statically instead.
