This is a rather old project but we have decided to add it to the showcase because it illustrates how you can create really good learning outcomes using very simple technology , along with a little editing magic from the Gaia Studio.
At the time that we did this project with The Star Academy in Stoke-on-Trent, the school had very little computer technology and were looking for a way of demonstrating how you could learn with IT. Pupils in the Reception Class demonstrated very poor knowledge of nursery rhymes and so the teacher was keen to boost this as part of early language development.
The plan that we hatched together was to video the children’s performance of rhyme at the same time as creating awareness of video production and technology. Armed with nothing more than a mobile phone camera and a coloured wall * the staff started to film the children in line with instructions from Gaia’s studio team. Those instructions guided the teachers to filming pupils so that could later be inserted into digital backgrounds. These were created by our digital artists,
The outcome was a short video, loved by parents, of the children performing their rhymes. Interestingly, we noticed a growing awareness of the camera and performance as the project went on. See if you can see it in the way the children react through this sequence of videos.
We commonly refer to green screen film production but the background does not have to be green. Technically, the process is called Chroma key compositing, or chroma keying.
Chroma key compositing, or chroma keying is a visual effects/post-production technique for compositing (layering) two images or video streams together based on color hues (chroma range). The technique has been used in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion picture, and video game industries. A color range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. Wikipedia
The reason that green is commonly used is that the colour does not usually feature in the human body, thus people are easily filmed and inserted into scenes without loss of part of the image. You can chose any colour as long as the foreground object does not contain that colour.
