For a presentation with Beamer, I would like to have a slide where a long list of formulas (maybe mixed with text) scrolls automatically within a certain part of the slide. This should look like e.g. closing credits in movies.

I have tried the idea from here based on animateinline from the animate package, but whenever I use environments like \begin{equation} ... \end{equation} or commands like \textcolor{red}{...} I get an error:

TeX capacity exceeded, sorry [main memory size=3000000]. \end{frame}

Ideally, the formulas/the text should be given within the document itself, but if a solution with an external PDF works fine, I'll take it!

Any ideas how that might work?

%put a longer paragraph of text in a box

%scroll the box content within a viewport of limited height


  {<box number>}       %filled box
  {<viewport height>}
  {<steps>}            %increase to enhance smoothness
  {<steps per sec>}    %adjust scrolling speed (not more than 25)

Complete example:


  % [#1] autoplay
  % #2 <boxnum>
  % #3 <viewport height>
  % #4 <steps>
  % #5 <steps per sec>
  \xsavebox{scrollbox}{\usebox{#2}}% make re-usable PDF XObject

    \strut Lipsum:\\

    \centerline{* * *}\strut

    That's exactly what I was looking for. Thanks for figuring this out for me! Great job. Nov 7, 2014 at 19:53
  • This now is giving an error. Can you update the code? Missing number, treated as zero. ...utoplay]{\mybox}{0.93\textheight}{400}{25}

    +1 This is amazing! Should be part of the animate package. Feb 15 at 14:06

    @Dr.ManuelKuehner Maybe as an example in the manual. (I am a bit of reluctant to extend the package's interface with specialised commands.)
