I began developing an online course in EBM and use videos for instruction. I thought it would be useful to tell others what I use. Videos are a useful way to teach others and are more learner-centered in that learners can use them when they want and can skip around in them for the information they need.
First off your videos need to be relatively short: 3-5 minutes is optimal. Longer than 10 minutes and learners will abandon the video. You have to be thoughtful on how to break up a longer topic into shorter chunks. They need to be engaging either through your teaching style or material presentation. They need to be consistent- use the same backgrounds, intro and exits.
Here’s what you need to make teaching videos: (Note: I am a PC guy. Mac has good built-in software that I can’t really comment on as I dont use Macs)
1) Video Hosting Service: YouTube and Vimeo are 2 of the more popular hosting sites. Some of the tools below also have their own site to post videos on. I personlly like YouTube. Here is my YouTube channel: (http://www.youtube.com/user/UABEBMcourse/videos?view=0)
2) Video Editing Software: I actually record myself giving intros and endings for each of my teaching videos. That way I have a “physical” presence. Because of this I need a video editor to splice these together with the main body of my video. There’s lots of video editing software out there. I use Corel Vidoe Studio Pro because it also contains a screen capture tool and seemed easy to use and wasnt too expensive ($60).

3) Screen Capture Software: I usually display a PowerPoint slide or a paper or a website when I teach. I use sceen capture software to record my computer screen and my voice. I like Screencast-o-matic (www.screencast-o-matic.com) because its easy and cheap (free). I bought the Pro version ($15/yr) so I have more tools available but the free version is good.
4) Video camera or webcam if you want to video something other than your computer screen.
5) Bamboo tablet: I use this to write on my screen when I explain/demonstrate how to make calculations. (http://www.wacom.com/en/products/pen-tablets/bamboo). This YouTube video shows me using the tablet and the digital drawing program I describe below:
6) Digital Drawing Program: this is the background I write (or draw) on with the Bamboo tablet. I like Autodesk Sketchbood Epress (http://apps.microsoft.com/windows/en-us/app/sketchbook-express/95d1acfb-4d64-487a-9e20-8d6f6d41cb54) because it was more intuitive to use and free. Khan Academy uses SmoothDraw (http://www.smoothdraw.com/) but I didn’t find it as easy to use.
7) Microphone. Often they are built in to your computer or webcam. I bought a high def one off ebay for <$10 because I wanted improved sound.
8) Audacity (http://audacity.sourceforge.net/) is software for recording and editing sound. If you want to just do voice recordings this is a good program.
So that’s it. For a minimal outlay of money you can develop pretty good quality videos. There is a learning curve on editing. You will also have to decide your style. Look around at other videos and do what works for you. This guy (http://www.youtube.com/user/bozemanbiology?feature=watch) has incredible videos but they take a little more time and skill to make.
