  1. Green Screen Video Effects Enhance Your Classroom Video Projects

  2. Introduction • Green screen technology is the basis of the effects seen in everything from the latest Hollywood blockbusters to the weather forecast. • Learn how to create your own blue or green screen, light your backdrop & subject, shoot your video & how you can replace the screen with your own backgrounds. • In what subjects / grade levels would you like to use the green screen video effects?

  3. Lighting Video Camera Green screen tripod Props / costume color – NOT green or blue! Digital images Fire Wire Video Editing Software Overview • Quality In – Quality Out: Make sure that you have a good background, contrasting colours for clothing & props and good lighting.

  4. Hollywood Goes Green! • Numerous green screens were used to create the backdrops for this video. • Stargate Studios Virtual Backlot Reel 2009

  5. Third Grade Science Project • “How Star Wars Was Made”

  6. Green Screen Options • Green Screen Options: • Green or blue poster board / fabric **Go for something that is quite matte. • Green Paint • Pinnacle Ultimate – Contains a green screen ($129.00) • • Build a green screen – youtube video

  7. Lighting • Green Screen & Lighting • Other lighting recommendations

  8. Windows Movie Maker Tutorial (Wiki – How To) • Edit your video clips before you add your green screen effect • Make sure that your background image or video lasts as long as your video clip that you are overlaying. • EXTREMELY important that you don’t wear blue or green or use blue or green props!!! • Fix the chromakey colour for WMM • More “Blue Screen” Tips from Discovery Education

  9. Stock Footage & Photos • For some scenes, it will be impossible to get your own background video or photos. If you or your students need to get the image off the web, make sure that they choose a “large size” image so that it doesn’t appear pixilated in the video. (This is probably also a good time to talk to your students about Creative Commons.) • • Create your own stock footage / photo library

  10. Using Green Screen Effects in Pinnacle Drag the video to the second video track.


  12. 1. Select the video in the timeline, then choose Toolbox > Add Video Overlay Effects 2. Select the Chroma key tab 3. Use the eye dropper to choose the background colour.


  14. The Chroma Key Controls • Go through the controls pretty much in the order they appear. • Start by selecting the colour with the eyedropper. Then move the colour tolerance up until most of your background vanishes. • Next, use the saturation minimum control to tidy up the key - so that everything in the background is removed. • Use the softness control to adjust the strength of the background image . • The transparency slider fades out your foreground image. • Spill Suppression control acts on the edges of your objects, removing any green fringes or hues that can appear on complicated edges or semi-transparent objects.
