When one is asking beamer to generate notes on a second screen, a small version of the slide is also produced.
This is troublesome when it comes to a slide containing a video.
In my case (movie9
+ Acrobat Reader), the video is not placed at the
correct location and is partially visible on both screens.
Is there a way to exclude the movie elements from the second screen slide thumbnail?
Here is minimum example of the issue:
\documentclass{beamer}
\usepackage{graphics}
\usepackage{media9}
\usepackage{pgfpages}
\setbeameroption{show notes on second screen}
\begin{document}
\begin{frame}
\includemedia[%
addresource=sample_mpeg4.mp4,
height=\paperheight,
width=\paperwidth,
flashvars={
flv=sample_mpeg4.mp4
&autoPlay=true
}]{foo bar}{player_flv_maxi.swf}
\end{frame}
\end{document}
You can find the sample video on the Apple website (3rd one).
I compile the document with pdflatex
and view it using Acrobat Reader (9.4.1) on Ubuntu 10.04.

There are two problems with your example:
As Beamer frames have default left and right margins, a video resized to the width of
\pagewidth
will extend beyond the right edge of the frame into the second screen which is reserved for the notes. This is not amedia9
specific issue as any box with this horizontal dimension would behave similarly.If you really want to have a video box filling up the whole frame it must be centred within the frame. The macro
\centerline{...}
is an option.The beamer option
show notes on second screen
tries to copy a rescaled version of the video into the thumbnail image at the top right corner of the notes screen. A video box is an interactive PDF element similar to a hyperlink. However, rescaling of such elements does not work for technical reasons. See section 58 of the PGF manual for details.Therefore, repeating the video on the notes screen must be suppressed. This can be done using the
[typeset second]
frame option and by enabling the beamer optionsecond mode text on second screen
.Here is a possible solution:
