The prediction market experts and industry players should tap into the power of videos.

The Scientist urges the science researchers to produce videos and publish them on YouTube.

#1. CLUNKY WAY: Write slides on your MicroSoft PowerPoint software (a tool that was not meant for the Web), add audio, and publish the webinar on one little webpage with low visibility and popularity —as Robin Hanson did recently.

#2. USABLE WAY: Create your video (visuals + audio) using some DIY software, and publish it on YouTube (so any prediction market blogger is able to embed your video widget and help you propagate your message further by igniting some kind of viral marketing process) —as Jed Christiansen did recently.

That said, the real point to drill is what kinds of images to put in a video on prediction markets. I’d suggest to put text, mainly. Most images are a distraction, unless they convey a point, like a chart can do. (Of course, tests and surveys should determine that.)

UPDATE: Jed Christiansen…

[...] For reference, I put the presentation together using Keynote, which is Apple’s presentation software. You can do largely the same thing with PowerPoint if you wanted to, but I find Keynote easier to work with for my purposes.

I would argue against using largely text in a video. A person can’t effectively read text and listen to someone speaking at the same time, let alone translate “bullet points” to real sentences while listening to someone speaking. That’s why I used selected images with key points and spoke over them. I’ve learned a lot about presentations from the blog Presentation Zen: http://www.presentationzen.com, and highly recommend it for anyone that does any sort of public speaking or presenting.

YouTube is certainly the way to go, publishing-wise, but I had to fiddle with the original video that I uploaded quite a bit in order to keep the quality high enough.
