Video Editing: A Step Ahead With Green Screen Technology

Video Editing has never become as easy as ever with green screen technique. The technique is also called chroma key editing. It is editing technique in which two images are fused together to create a single and finished image. Photographers use this technique extensively in film and television to create a wide range of special effects.

Procedure of Green Screen Technology:

“Chroma” means color in video jargon and chromakeying works by shooting a subject against a background of a very simple and uniform color. A photographer uses blue or green color screens because they are as far away from human skin tones as it is possible to get. Additionally it is easy to use these two colors, as they are sensitive to the image sensors in the camera. The subject should not wear blue or green color clothes that can be same as that of the background screen. It effects the editing of the photograph or video. The background screen should be uniformly lit and even the foreground subject. This is to prevent any kind of shadows on the subject or on the background screen. Keep subject and background as far apart as possible. After the shooting, editing software replaces the background color by another shot chosen by the photographer. The most common example is that of a map behind the weatherman in the news stations. The person is actually standing in front of a green or blue color screen that replaced in the control room with a background image of a map.

Uses of the Green Screen Technology:

Video editing with chroma key technology is a user-friendly procedure to transform your videos and images and personalize them the way you desire. Mainly professionals deploy this method and they use for photo shoots for magazines, advertisements, newspapers and for the Internet. In Portrait Photography, a photographer uses such kind of technique. One uses the method commonly in the television or news stations. A video editor uses the procedure often in films that saves time and money in shooting. If you see your favorite actor climbing the wall or getting invisible, it is the result of this technology. The people who have photography as their hobby can also use it. One can use the technique at home as well. You need to mount a solid blue or green colored sheet on the wall. Take the pictures that you need to replace and after shooting the foreground subject use an advanced photo program to edit. This will eliminate the background of the picture and replace it with another. Teachers can also use the technology by placing the image of a student in the area of the topic that they are learning. It is great fun for a person to use this advanced technology with expediency.
