I gave a lecture yesterday on animal minds, and in the course of it tried to show some YouTube videos in Keynote by linking to the pages (tool using crows, by the way, and the excerpt from Life of Birds by Attenborough on Japanese crows using stop lights to get nuts they dropped under car tyres, very cool. The students loved it). Great technical problems.
Today (of course, a day late!) I came across TubeTV which downloads the Flash videos for embedding in Keynote directly. Works, is free and is very useful for when you don't have enough material for the entire lecture.
Highly recommended (as, of course, is the new Keynote from Apple: I have recovered Powerpoint presentations munged by PPT by opening them in Keynote, and it is a much better interface).
I would hope it's free, since it looks to be a shiny wrapper around the open source app youtube-dl.
I like shiny wrappers, since it means I don't need to remember switches in a CLI.
I know that this is not related to the post, but I am trying to make it easier for you to find you that you've been tagged by the mutating meme.
