We decided to shoot the videos indoors, actually in one of our classrooms. All the dialogues were performed in front of a green screen. Green screen for indoor shoot, or chroma keying, is a special effects/post-production technique for compositing (layering) two images or video streams together based on colour hues (chroma range). Green screen technology is the basis of the effects seen in everything from the latest Hollywood blockbusters to the weather forecast. The idea is simple. If you shoot a video with a single coloured backdrop (green is often used) the computer software allows you to make that colour transparent – replacing it with any other video clip, graphic or still image. With green screen, it’s simple to superimpose anything or anyone into any shot. You can transport yourself to the moon, appear in your favourite film, or make a presentation along with all the relevant facts and figures.
