To mimic the result of a video with animated frames, I started to use \transduration.

However, I am missing something.

There is a gap between the overlay I want to show and the \transduration applied to it.
- overlay 1 is supposed to last 10 seconds but actually lasts only 2 secs)
- overlay 2 is supposed to last 2 seconds but actually lasts only 10 secs)
- ...

MWE


\documentclass{beamer}

%\setbeameroption{show notes}
\setbeameroption{show notes on second screen=right}
%\setbeameroption{show only notes}
