I have a video recording of a presenter, going through her PowerPoint presentation and taking crowd questions.
I'd like to be able to upload the video of the presentation along with the PowerPoint presentation, shown side by side.
There are plenty of YouTube videos that have this sort of thing going on. For example, most DEFCON presentations (example) show the recording of the presenter in a corner, the logo below, and the slides taking the rest of the video.
Is there a simple way to do this?
