Beamer - blank black frame

Question

I'm making a presentation with LaTeX Beamer package. And I want to have a slide where the screen is all black so I can use other media. Is there a way to insert a black slide simply?

If you were using Impressive to display your slides, it's as simple as pressing B at the right moment... — Seamus, Apr 02 '11 at 15:38

@Alan Munn changing the background colour won't change all the frame to black. The structural elements will still be there. — Seamus, Apr 02 '11 at 15:54
@Seamus Other than the navigation symbols, changing the background canvas does exactly that. No other elements are visible. So Herbert's solution is an exact duplicate of the solutions posted in the question I reference. — Alan Munn, Apr 02 '11 at 16:17
@Alan No. The relevant difference is the plain option that turns off, say, the top bar and lower bar from the infolines outertheme. — Seamus, Apr 02 '11 at 16:27
@Alan and in fact, even if the answers had been identical, I think the questions are different enough that I don't think this should be closed... — Seamus, Apr 02 '11 at 16:42
@Seamus I just noticed it is the same with evince - my pdf viewer of choice. — pirad, Dec 08 '11 at 16:09

\documentclass{beamer}

\begin{document}

\frame{foo}

\bgroup
\setbeamercolor{background canvas}{bg=black}
\begin{frame}[plain]{}
\end{frame}
\egroup

\frame{bar}

\end{document}

You need \setbeamertemplate{navigation symbols}{} inside your group to make the slide totally blank. – Seamus Apr 02 '11 at 15:56

I know, but it may still be useful to have the symbols – Apr 02 '11 at 16:18

If you have \mode* on then the background color remains set for subsequent slides even if you have the command wrapped in a group. This works:

\mode<presentation>{
  {   
    \setbeamercolor{background canvas}{bg=black}
    \begin{frame}[plain]{}
    \end{frame}
  }
}
\mode<presentation>{\setbeamercolor{background canvas}{bg=white}}
\mode*

I assume that's in the preamble, how exactly do you switch within your document from one slide to another? – Joanne Demmler Aug 01 '13 at 14:26

It might additionally be necessary to use \setbeamertemplate{background canvas}[default] before \setbeamercolor{background canvas}{bg=black}. Have a look at this post.
