Green Screening

Green screening is the technique of filming or photographing subjects on a green (or blue) background with the purpose of turning all green (or blue) to transparent. This allows the background to be seen through. The process is widely used in TV shows, news and weather reports as well as for special effects in movies.

For some perspective and inspiration! Check out this amazing example of green screening in the movies.

The possibilities that are enabled through “green screening”  are certainly exciting! The applications to learning are only bounded by imagination!

The most exciting aspect is that Green Screening is now highly accessible and easy.  Green screening was once only an opton with high end software at great expense but it is now built in to many standard pieces of video editing software as well as in apps for mobile devices. So let’s have an explore!

Premiere Elements: is a cut down version of Premiere Pro and has Green Screening as an option. This works across Mac and Windows. A nice feature of Premiere Elements (and Pro) is you choose where your project and files belong so you can move computers and be more organised, that said it requires a bit more tweaking to get green screening to work well.

Premiere Pro, Final Cut Pro and other high end Software: These higher end software options have a lot more fine tuning and the option to be more selective with areas and to edit your video prior to make it work better. (More on this later)

Ideas for use in Learning: (and examples)

There are a number of ways you can use green screening to enhance learning.  Some ideas are:
– Narrating a story
– creating a news bulletin
– presentations with stimulus material behind
– a TV channel
more ideas and Links coming!

Techniques, Tips and Tricks:

– The “secret” is to have an evenly lit smooth green surface.
– The further you are away from the green screen the less likely you are to have a green reflection on your subject.
– animation sequences from photos on a green screen work really nicely and can be created with apps on mobile devices or with great editing software like Adobe Premiere pro.

Links and Resources:

There are a number of schools that are doing awesome work with green screening. We hope to highlight some of these in this area. Stay tuned!

Physical Resources:

Getting gear does not need to be expensive. Large bits of material can be bought through eBay and other places very cheaply.
Green Screen Backdrop Frame: $60 on Ebay
These frames are working well for us so far. They come with three pieces of material but they were poor quality and we bought material separately.
Muslin Cloth Green Material: 3m x 3.6m cloth for $30 size has a loop to fit the backdrop pole through and drapes over the frame tightly with the clamps. The larger 3m x 6m cloth for $41 cloth is great for large setups.
Lighting: Individual softbox lights for $48 each OR a set of three softbox lights and stands for $105
Extra Clamps: 5  clamps for $12 OR 10 Clamps for $21 these have proven to be invaluable.
