Is it possible to set a global transition effect for all frames instead of specifying the effect again for each frame?

  • Yes. There is a work around in @diabonas answer below. \addtobeamertemplate{background canvas}{\transfade[duration=2]}{} – sajjadG Aug 26 '13 at 3:21

Short answer: no.

The longer answer is that the way the frame environment is set up in beamer deliberately resets the transitions and buries this deeply within the code. That reflects the original author's position that transitions should be used sparingly and for single frames only. Altering this behaviour would require a significant rewrite of parts of beamer.

  • I'm not questioning the developers design choices, but of course there are use cases where a global option is useful. I guess I'm going for a massive search & replace then :) Thanks for the info, saved me a lot of time. – jack Cosmi Jul 7 '13 at 15:51
  • If I were starting from scratch, this is something I would make available as an option: however, I'm very wary of making major changes to beamer at this stage. – Joseph Wright Jul 7 '13 at 15:53
  • @JosephWright It would be a nice feature. It is hard to add effect for every frame separately and adds a lot of same code which is a bad attitude. Please consider adding this feature in future. Thanks. – sajjadG Aug 25 '13 at 19:19
  • @sajjadG As I said in a comment, without more-or-less starting from scratch this would be very hard. Also, though, I do sympathise with Till Tantau's position: slide transitions should really not be used for every slide. – Joseph Wright Aug 25 '13 at 19:22

As a workaround similar to the one provided in Is it possible to define transduration for frames created with allowframebreaks?, you can add the transition effect to the background canvas template so that it is reactivated automatically after each reset:

\documentclass{beamer}

% Add global transition effect \transfade
\addtobeamertemplate{background canvas}{\transfade}{}

\begin{document}
\frame{\centering\Huge1}
\frame{\centering\Huge2}
\frame{\centering\Huge3}
\end{document}

An other way is to use impressive for your presentations. This software allow you to add transition effect between pages of your pdf.
