Removing black spaces of embedded video in beamer

I am experiences some issues when including videos in my beamer presentation. Here is my frame,

\begin{frame}{Frame Title}
\movie[width=6cm,height=4.5cm]{}{videos/test.avi}
\end{frame}


The problem occurs when I set the width and the height of the video. When I enter Presentation-mode of my PDF-viewer, black spaces occur at the sides of the video.

Is there a way to completely get rid of these?

I tried forcing the background color to white before the frame (\setbeamercolor{background canvas}{bg=white}), but that didn't solve the issue.

MWE:

\documentclass[11pt]{beamer}

\usepackage{multimedia}

\usepackage{tabularx}
\usepackage{amsmath, amsthm, amssymb}
\usepackage{gensymb}

\begin{document}

\begin{frame}
\end{frame}

\begin{frame}{Frame 1}
\movie[poster,autostart,width=6cm,height=4.5cm,repeat=true]{}{rho.avi}
\end{frame}

\end{document}


The video is here: https://ufile.io/fb2de

• Maybe have a look at tex.stackexchange.com/a/143102/36296, this shows how to include full width images. But if your video has another aspect ratio then the presentation, some margins are inevitable. – user36296 Dec 19 '16 at 10:03
• @samcarter Is it possible to override the margins, maybe by setting the background color or some other "dirty" trick? – BillyJean Dec 19 '16 at 10:08
• Can you make a compilable MWE that can reproduce your situation. Maybe with some dummy video we can access? – user36296 Dec 19 '16 at 10:22
• @samcarter added a mwe with a video. when I enter presentation-mode with my pdf-viewer, black margins occur. – BillyJean Dec 19 '16 at 10:33
• This kind of animation could as well be embedded using the animate package, if you have the files of the single frames (preferably as original vector graphics) available. – AlexG Dec 19 '16 at 11:09

You can use the media9 package instead of multimedia (comes with beamer), which requires to convert your video to .mp4 first (e.g. here or wherever). It's worth the effort as media9 allows to include the video physically in the PDF, means you don't need to carry around the actual video file and you're not dependent on any codecs available on the target PC (which would be the case with an external .avi file and multimedia).

\documentclass[11pt]{beamer}

\usepackage{media9}

\usepackage{tabularx}
\usepackage{amsmath, amsthm, amssymb}
\usepackage{gensymb}

\begin{document}

\begin{frame}
\end{frame}

\begin{frame}{Frame 1}
\includemedia[
width=6cm,height=4.5cm,
activate=pageopen,
keepaspectratio,          % optionally useful
transparent,              % optionally useful
playbutton=plain,
flashvars={
source=rho.mp4
&autoPlay=true
&loop=true}
]{}{VPlayer.swf}
\end{frame}

\end{document}


• In case the player's and the video's aspect ratios don't match exactly (due to resampling of the video while viewing) it is worthwhile adding option transparent. It makes the player's background transparent and further reduces the occurrence of black lines around the video – AlexG Jan 3 '17 at 12:31
• Thanks. I tried out your example with rho.mp4, but in the PDF nothing plays - it only shows a grey bar with a play-triangle inside it. Nothing happens though when I push it. Is the part VPlayer.swf correct? – BillyJean Jan 3 '17 at 12:47
• @BillyJean : Okular doesn't support the embedding method of media9. And only the Windows version of Foxit works. – AlexG Jan 3 '17 at 13:37
• @BillyJean : Installing and running A-Reader and FlashPlayer in Wine under Linux could be an option for you. – AlexG Jan 3 '17 at 16:06
• @BillyJean I'm sorry, but I didn't knew there would be issues with other pdf readers. Unfortunately I can't provide another solution for them. – thewaywewalk Jan 3 '17 at 22:09
