Green Screen Session

To gain further understanding of how to shoot and edit with a green screen, I asked one of Leyton's media technicians to show me how to do it. I learnt a lot about the whole concept, such as how time consuming it would be to create a frame that genuinely looks good, and will probably not be using a green screen for my own music video, despite how keen I was on using it before.

Here is a write up of the steps we took:

1) Put down flooring

2) Sort out the green background and make sure it is matte

3) Film the subject
If the subject has dark hair or skin, a dim hair light would be sufficient to illuminate the dark hair/skin.
Any new angles must be simulated eg. three different angles cannot be filmed at the same time, they must be filmed seperately

4) Adobe After Effects > New Composition > Preset HDTV 1080 25

5) Import video

6) Effects and presets > Keying > Keylight 1.2 > Screen Colour > Remove background

7) Get an image for the background and layer it behind the filmed image

8) Play around with minor effects accordingly.
The After Effects ring shows the spread of light and can make a vignette.
To make a silhouette, select the image and then turn the white output down.
Can also create masks to mark out a certain area.
