[Tex/LaTex] Can algorithm of shrink in beamer frame be improved

beamer

I used to [shrink] routinely beamer slides,
when just a few percent more content is on the page, that could fit by default. It makes no noticeable aesthetic change in the size of the font, but does not degrade the beauty with clipped object or text. Why I asked
How to shrink in 16:9 beamer mode? is, that the changed aspect ratio has an impact on the aesthetic of the frame.
It looks like the algorithm of shrink simply adjusts the height of the content to the height of the frame. As shown by the MWE below, the shrinking, what can be hardly noticed in 4:3 mode, is quite ugly in 16:9 mode.

\documentclass{beamer}
%\usepackage[orientation=landscape,size=custom,width=16,height=9,scale=0.5]{beamerposter} 
\usepackage{blindtext}
\usepackage{graphicx}

\begin{document}

\begin{frame}{Frame Number 1}
\blindtext[1]\par\includegraphics[width=4.8cm]{example-image-golden}
\end{frame}
\begin{frame}[shrink]{Frame Number 1}
\blindtext[1]\par\includegraphics[width=4.8cm]{example-image-golden}\qquad
\end{frame}

\end{document}

Best Answer

you can use shrink=5 which looks a bit better

the manual says:

The best way to use this option is to identify frames that are overly full, but in which all text absolutely has to be fit on a single frame. Then start specifying first shrink=5, then shrink=10, and so on, until no warning is issued any more (or just ignore the warning when things look satisfactory).

Using this option is very evil. It will result in changes of the font size from slide to slide, which is a typographic nightmare. Its usage can always be avoided by restructuring and simplifying frames, which will result in a better presentation.
