The interest in Green Screen seems to be gathering momentum. I think it's one of those techniques which is a mystery to many people but once you know how it works is really simple. The coloured background is replaced by another image using software; dead simple.
Below is a little test video we made with the media team at a local school. It became clear during this exercise that the process was exciting for the children and well within their capability. Using the software to replace the background and edit the sequence was within the grasp of some year five children.
The technique can not only help with ICT skills but potentially address teamwork, speaking and listening, writing, drama, storytelling, artwork. The next project will be a journey to the moon.
Bought 3 yards by 1 yard of green felt from Leeds Market and used Velcro to attach it to a wall between the photocopier and a desk. £20.
The school already had a MacBook which we upgraded to iLife9 - iMovie in iLife 9 is capable of green-screen overlay – earlier versions aren't. £40
Came up with the idea of a hiker who couldn't tell his left from his right and ended up in unexpected places download the script
Put the camera on a tripod and connected it directly to the MacBook using a firewire cable.
We recorded the action directly into iMovie.
Children sourced background images and imported them to the MacBook via a memory stick.
Edited the sequence in iMovie – green screen is a simple drag and drop.
Imported the music track to enhance.
I shall be setting up green-screen areas in a few local schools. If you'd like to have one and would like help please drop me an email.
I've been reviewing some of the projects I have been involved with recently and thinking about how they could have been improved.
The conclusion I have come to is that most creative projects are to some degree chaotic and uncertain; You can't always predict how they are going to run. You have to be flexible and responsive to new ideas and directions as they come up.
That said, there is possibly value in at least attempting to structure the management of creative projects around tried and tested ideas. A creative project, like any other, has process steps and milestones. One reason why creative projects often fail is because not enough time is spent understanding the purpose of the project and refining the ideas around that purpose. Sadly is is all to easy to forge ahead with half baked ideas with no idea of why we're doing it!
Step 1: The brief
Be sure about the purpose of the project and why it has come about. You might call this the creative challenge.
Get down on paper a description of what you hope to achieve, who it is for and why it is important. For example – Encourage year four children to take pride in their town by revealing its glorious history. We're doing this because ……
Set out what you want to achieve, how you are going to approach it, who it is for and why it is important.
Step 2: Ideas
Once we have a brief we can set about coming up with ideas (in the above case for revealing the town's glorious history). Not enough time is ever spent coming up with ideas or evaluating them. I would say that this is one of the biggest reason for the failure of creative projects. The temptation is to settle on the first and most obvious idea you come up with. Often the crazy ideas are sidelined at the outset, and yet these are often the most interesting.
Make plenty time for coming up with as many ideas as possible, even the crazy ones, and evaluate them according to the brief.
There are many techniques for coming up with ideas – here are some. Thinking Hats for evaluating ideas, Mind Mapping with which I'm sure you are familiar, and a favorite of mine, The Creative Whack Pack
Step 3: Planning
Do you decide on the team and resources before you have an idea or after? I would say that it's sometimes better to come up with the idea first with a small core team and then pitch for people and resources once you have the idea. That way you'll get what you need rather than having to put up with what you have got.
Careful planning of the resources and the timetable, setting of realistic deadlines and getting agreements.
Step 4: Action
Well planned activity with a great idea behind it should be exciting. Any problems will be quickly resolved because of a solid commitment to the purpose of the project.
Step 5: Celebration
The positive outcome should be shared and celebrated beyond the immediate team. The more external praise and feedback the better. A public film screening, a party for those who contributed, a commemorative web page. The legacy of successful projects should be preserved so that the benefits can be made available to the greatest number of people for the longest amount of time.
Step 6: Review
A constructive examination of the project should always be part of its legacy. Did it meet the brief? What were the points of learning and so on.
This may all seem obvious – in which case I apologies – but I need to remind myself just how important these project steps really are and that to skimp on any of them will weaken the outcome.
The grizzly times of the Tudors and Henry's willy nilly habit of chopping off heads has a natural appeal for year four children.
At this school we wanted to combine music, writing, film, animation and the wonderful technique known as green-screen – or perhaps blue-screen; Chroma Separation Overlay, CSO if you want to show off.
This film takes some of the more unsavory facts about life on the Mary Rose as a starting point. We also wanted to involve the children in a variety of interesting ways – particularly to include some of the less confident and disruptive children. For example, some of the drawings we included may be very simple and not hugely demanding to create but we found a place for them in the finished piece.
There is a natural tendency for the professional film maker to be concerned about maintaining a high standard but this must not be at the expense of including less confident children. This should not just be a showcase for the most talented children but a way of unlocking talent and confidence in the least confident ones. Otherwise why are we doing this?
A mind mapping session to unlock all the facts the children had learned about life on the Mary Rose
Using Garage Band create a rap backing track
Listen to the backing track and practice writing and performing words to the rhythm of the track.
The children in their own time (and with the rhythm in their heads) all write their own rap songs
We select the best ideas from each of the songs to create a single rap to be used in the film
Tasks are introduced and allocated to the team – animating the ship, drawing pictures, operating the camera and lights, recording the sound, performing, setting up the green screen, finding images, directing etc.
Animating session. We filmed the ship against a coloured screen and created the sea out of rolled up coloured paper which we animated manually. Pictures were drawn, biscuits were filmed, flames and rats were scanned. The scurvy ridden faces were drawn.
The green-screen session. The screen was set up facing a large area of windows so we had a lot of soft natural light. This was a hugely popular activity. The children decided to call this set-up the magic wallpaper.
The backing track was played from a CD player. Jobs included director, camera operator, sound and performers.
Editing. The editing for this was too complex for the the schools own software so most of it was carried out off-site. However I think there is scope in future for sections of these films to be edited by the children.
I liked the wide range of tasks and skills that this project involved, it was very inclusive. It didn't just use traditional animation techniques but required a range of solutions. There was a high degree of problem solving particularly making the ship and water move – the children were fully engaged in finding their own way of doing this.
Some of the less confident children appeared in front of the camera and some of the more modest drawing attempts were used in the film – this was obviously appreciated by the children concerned.
We had some positive discussion about making mistakes – if something didn't work we called it learning and improving. A mistake in the filming could be an entertaining out-take.
The green-screen was such a success that I am helping the school set up its own permanent green-screen (magic wallpaper).
