I found the pair pandoc+beamer perfect for some kinds of presentations. Recently I used them to prepare the keynote and the proceedings for a conference talk: https://bitbucket.org/Maurizio_Tomasi/adass2018-julia/src/master/ https://bitbucket.org/Maurizio_Tomasi/adass2018-julia/src/ma... (The keynote is in "presentation.md", and the paper in "article.md".) I had to customize a few pandoc's defaults (see the Makefile) and even had to use a Python filter to tweak the output, but the result was excellent: once everything was in place, creating the slides required no effort at all. I was even able to switch the format from 4:3 to 16:9 in a breeze, once I learned what the resolution of the projector was.
