I have a simple question for beamer programming. I've been looking around and was quite surprised not to have found a quick answer for a seemingly simple thing, so I am posting it here.

I have a list and would like to uncover the sentences of a single item from the enumeration one by one (basically, it shows resolutions of multiple choice question; but I would like the resolution of each item to be shown little by little).

I would be grateful for any help. My failed attempts used only, uncover, and pause, but couldn't do the trick with those.

    Does this answer help you for your purpose? – Ludovic C. Oct 28 '13 at 00:20
  • Not quite, it creates blocks, but that is not my purpose. I just want a sentence to be revealed little by little (possibliy for making a video of my screen as well). – MJS Oct 28 '13 at 18:22
  • Also, I would like the sentence to appear once and thats it. I don't the sentence to appear very dim at first and then uncovering it... – MJS Oct 28 '13 at 18:29

Is this what you are looking for?

\documentclass{beamer}

\begin{document}

\begin{frame}

\begin{enumerate}
\item Here are many sentences to present this item. \uncover<2->{This is the second one. \uncover<3->{And here comes a third one.}}
\uncover<4->{\item Bar}
\uncover<5->{\item Foo. \uncover<6->{Bar. \uncover<7->{Baz.}}}
\end{enumerate}

\end{frame}

\end{document}

Outputs

EDIT I did not like the typesetting of my answer (too many uncover) so here is an alternative for the same output (I added setbeamercovered{transparent=0} on the request of the OP). Here only the \pause command is used.

\documentclass{beamer}

\setbeamercovered{transparent=0}

\begin{document}
\begin{frame}
\begin{enumerate}
\item Here are many sentences to present this item.
\pause This is the second one.
\pause And here comes a third one.
\item \pause Bar 
\item \pause Foo.
\pause Bar.
\pause Baz.
\end{enumerate}
\end{frame}

\end{document}

  • I am still having some trouble because the items still appear very dim in the background before being uncovered, so for some reason I can't replicate your example... – MJS Oct 29 '13 at 16:04
  • @MJS Try to set \setbeamercovered{transparent=0} in your preamble. – Ludovic C. Oct 29 '13 at 16:07

    @LudovicC. You can use \item<...> instead of \uncover<...>{\item ...}. – Paul Gaborit Oct 29 '13 at 16:09
  • @PaulGaborit I agree if you want to reveal all the content of the item but what if you want to show only some part of this item? – Ludovic C. Oct 29 '13 at 16:10
  • @LudovicC. Try it (third item): \item<5-> Foo. \uncover<6->{Bar. \uncover<7->{Baz.}} – Paul Gaborit Oct 29 '13 at 16:15
  • @PaulGaborit Yes sure for this part, I thought you were speaking of all the uncovers command. I am currently trying to improve the method to get it lighter to typeset. Edit in progress. – Ludovic C. Oct 29 '13 at 16:17
