A good presentation is not a matter of software. You can make outstanding presentation without embedded videos and fancy transitions. And you can make them on PowerPoint, Keynotes, Libreoffice, or translucent sheets. Focus on a clear storyline, and key messages of each slide, keep it simple, use some visuals instead of a wall of text, use bullet-points wisely... People spend months on a project and then 1-2 days on the final presentation and wonder why the audience does not understand / is bored. Management consultants (whose main output are presentations) start working on the final deck from the first weeks / days of the project.
