Film Featurette and Resources:
Instruction- Top 10 Green Screen Filming Techniques
- Limit shadows and wrinkles
- Keep lighting diffuse, not harsh. Typical classroom lighting does this pretty well (you may need to cover windows)
- Make sure subject has nothing green on (unless you want it invisible; think: disembodied floating head)
- Have subject stand at least 3-4 feet away from green screen; more if possible to avoid spill
- Avoid curly, frizzy hair (Yul Brynner Andre Agassi=Good; Don King=Bad)
- The less movement, the better
- Make sure all action to be include has green behind it, but it's OK if the edges of the frame don't have green. You can create a Garbage Matte to get rid of those non-green areas.
- If you plan on using extra lights, light the subject just as you would if it weren't Green Screen, but keep spill off of the screen
- Try to have your subject lighting similar to background lighting so the two shots look organic together (consider angle of light, intensity, color, etc.)
- Have talent leave frame at end of take for a second or two to film just pure background (mainly for iMovie)
- Important: iMovie > Preferences > General > Show Advanced Tools
- Adding background
- Adding green screen clip
- Adjusting length
- Garbage matte, if necessary (watch for cut-offs)
- Subtract Last Frame
- Adding music
- Exporting
Task
Plan it Out - Pick a background clip from the supplied folder
- Pick background music from the supplied folder
- Develop a scenario for your talent to act out that's appropriate for the background clip; make it FUNNY!
- Include dialog if you wish, but it's not necessary
Shoot and Build the Scene - Film your green screen clip, following as closely as possible the best practices above
- Let the background clip you chose be your guide on length, but 10-20 seconds is fine
- Remember to have subject(s) leave view of camera at the end for a second or two (background only) before turning off camera
- Create a new iMovie '09 Project
- Import your background clip from the supplied folder (File > Import > Movies)
- Import your green screen clip from the camera
- Add the background clip to the Project, then the Green Screen clip on top of it
- Adjust end points (Tip: use the Precision Editor by clicking on the Actions Gear [
] of the background clip ) - Enable Subtract Last Frame checkbox on Green Screen clip (double-click on it to reveal the Inspector); you can disable this if you don't like the effect by unchecking
- From a Finder window, drag your music onto the Project background (not onto a clip; background should turn green)
Publish your Work - File > Export Movie > Medium
- Add to someone's PL blog
- Be prepared to talk about the good, the bad, and the ugly
- Re-assemble by 5:00 at the latest (we'll start earlier if all are accounted for)
