Green Screening

 

 

The Washburne Effect Keynote to iMovie through QuickTime
By Tom Kowalewski,

1. Open Keynote and create a blank presentation slide.
2. Using the slide Inspector, change the size of the slides to 960 pixels wide by 540 pixels high (iMovie large size).
3. Make a fern green background on the blank first slide.
4. Duplicate the slide so you have a pair of fern green slides.
5. Leaving the last slide blank fern green, you may place text, graphics, video clips, or your other creative items on as many slides as you need to tell you digital story*.
The key is to leave the last slide blank fern green because iMovie needs this to chroma key out the green from the clip.
6. Save your Keynote presentation.
7. Share the Keynote to iTunes from the Share Menu, exporting it to your desktop.
8. Leave the Playback Uses set to Fixed Timing and delete the Slide Duration and Build Duration before clicking Send.
9. Select a location to export and click Export.
10. Keynote saves the file using a QuickTime codec to iTunes.

The iTunes program will open, but we don’t need it right now, so just go to the iTunes application menu and select quit iTunes.

11. Import the movie file into iMovie using the File > Import.
12. Make sure the Show Advanced Tools is checked in iMovie preferences.
13. After importing the clip into iMovie, you can green screen your Keynote video into your iMovie just like any other green screen clip in your project.
Creativity and Innovation is now in the hands of all students.
