Thanks to Tom Barrett for publicizing, on Twitter, the TeachMeet09 Ed Tech Roundup. I happened to catch one tweet and watched a two-minute tutorial about greenscreening and iMovie 2009 by Kevin McLaughlin. It was so easy, once the advanced tools were turned on!
I started thinking about the use of this in our technology classes, and suddenly realized that one could put a green background (#00FF00) as one of the user-created backgrounds in PhotoBooth on the Mac, record the greenscreen video, and then use Kevin's tip for using that in iMovie. This way, each student has their own green screen!
Steps
1. Import a 500x500 green (color #00FF00) solid color JPEG as the background in one of the effects boxes in PhotoBooth.
2. Record the video in front of this green background.
3. Save the MOV file.
4. Import the PhotoBooth MOV file into iMovie.
5. Import the background video into iMovie.
6. Use Kevin's tips.
(I realize you can import the background video into PhotoBooth and record yourself on top of it, but keeping the two videos separate gives you the option of applying additional effects and options to them in iMovie.)
Here is my feeble attempt to show you a quick finished product following the above steps.
