Presentations happen in a browser (full screen mode, no presenter screen). Both are solid, you can embed media (audio, video, links) as well as mouse roll-overs and so forth. You can use it to create presentations either with the JessyInk extension (which comes pre-installed with Inkscape), or with Sozi, a program that lets you create Prezi-style presentations (zooming and panning on one big canvas) from a SVG document. Inkscape never the less can be one way to make a multimedia presentation. Open/LibreOffice will just choke and become entirely unusable. No program will allow you to set in- and outpoint, set autoplay on or off and adjust the volume level for each media item.
If you are working with video or audio files, be prepared that you will have to jump through a few hoops on Linux.
#LATEXIT SERVICE NOT WORKING WITH KEYNOTE PDF#
PDF presentations generally don't allow videos though, which can be a huge drawback compared to Keynote. You might also want to look at Impressive for on the fly highlighting and transition effects (but no presenter screen support). For the presentation itself I employ the pdf-presenter-console package (unmaintained, but in the repositories, updated version: pdfpc, for a nice feature set but sadly abandoned check open-pdf-presenter).
#LATEXIT SERVICE NOT WORKING WITH KEYNOTE SOFTWARE#
You can use the Free software Scribus to create your presentations as PDF documents (Scribus now even has smart guides). Sure you could make your own styles, but typically presentations are done with very little time, and you just want to throw some things in, not modify styles just to see how it looks when you have three pictures on one slide instead of one. The LaTeX Beamer class templates look terribly scientific and are not usable for presentations outside academia and research just because of their graphic design (some notable exceptions exist, for instance hsrmbeamertheme has a refreshing look). A document with > 10 highres images in it will be so slow that you can't do a presentation with it. Trying to embed video files is even worse. Once you have added images which have a slightly higher resolution it becomes unusable and slow to the point that you just hate to work with it because you are spending time on waiting for it to save the document. In OpenOffice/LibreOffice you need much more clicks and sub-menus to align graphics or text. No matter how enourmous the graphics or media is, the next slide will always load instantaniously. these kind of situations can confuse and frustrate a presenter enourmously and Apple Keynote has covered this element in perfection. If the user presses "next slide", but the software is struggeling to render the frame promting the user to question if the "next slide" command was registered, maybe triggering it again, which then makes the software skit two slides ahead. What's key for a presentation software is to have very little lag when presenting slides.
It also handles all kind of media files and is still extremely fast at it.
What makes Apple Keynote "so cool" are the smart guides which let you align stuff with great efficiency and speed. Previous answers only seem to have second hand knowledge of what Keynote can. I can contribute describing the differences between Keynote, Impress and LaTeX Beamer.
