Free video tools for presentations

Turning a deck into video used to mean recording yourself reading it. These tools generate the narration, time it to the slides and render the file, so a presentation becomes something you can send to the people who will never make it to the meeting.

Going the other way is just as useful. A recorded talk, a YouTube link or an MP4 can become a summary you can skim, a deck you can present from, or a quiz that checks whether anyone watched it.
