Here is a frame with an itemize list where the items appear one by one. Is it possible to change the transition style between item 2 and item 3?

\begin{document}

\begin{frame}
  \begin{itemize}
    \item item 1 \pause
    \item item 2 with default transition \pause 
    \transdissolve
    \item item 3 with transdissolve transition \pause
    \transreplace
    \item item 4 with default transition \pause
  \end{itemize}
\end{frame}

\end{document}

Answer 1

To achieve the desired result of having item 3 dissolve, you need to change to

\item item 3...
\transdissolve<3>

This tells the 3rd frame to dissolve, which doesn't affect the rest.

As karlkoeller points out, you can adjust the duration with the optional argument [duration = ] with the time you enter. Additionally, there is the optional argument [direction = ] with the degree you enter. This affects the effects direction. See page 141 of the beamer documentation for more detail.
