\end{itemize}
```

4.2 Transition Effects

Beamer provides various transition effects to make slide changes smooth
and engaging.
4.2.1 Global Transitions
Set transitions for all slides:
```
\beamersetuncovermixins{<+->}{<.->}
```
This ensures a fade-in effect between slides.
4.2.2 Slide-Specific Transitions
You can define transitions for specific slides using:
```
\frame{
\transfade
\frametitle{Smooth Transition Slide}
// This slide fades in.
}
```
Common transition commands include:
 \transfade (fade-in effect)
 \transwipe (swipe effect)
 \transpush (push effect)

4.3 Overlay Specifications

Overlay specifications control when elements appear within a frame.
4.3.1 Using <n> to Define Steps
```
\begin{itemize}
\item<1-> First item appears first.
\item<2-> Second item appears next.
\end{itemize}
```
This technique is useful for stepwise content reveal.
4.3.2 Displaying Items Only on Certain Slides
```
\only<2>{This text is visible only on slide 2.}
```
This helps in controlling information visibility.

4.4 Animating Images and Figures

include them:
```
\input{introduction.tex}
\input{methods.tex}
\input{results.tex}
```
Each section is stored in a separate file for better management.
6.4.2 Using subfiles Package for Modular Slides
The subfiles package allows splitting the document while maintaining
independent compilation:
```
\usepackage{subfiles}
\subfile{chapter1.tex}
```
Each subfile can be compiled individually or as part of the main document.

6.5 Managing References and Citations in Large

Presentations
For research-oriented presentations, adding citations and references is
essential.
6.5.1 Using biblatex for References
