What Chroma Key Screen Should You Use - Green or Blue colored?

Camera compression code, that long term makes me smile. People shooting videos at home and using video cameras probably have never heard it. What does this term have to do with video shooting and how does it reflect our chroma key screen?

In the DV world, our DV home video cameras use camera compression codec that does not compress the data of the pictures we are shooting into small files. Not compressing the files means cutting the "edge" and that means losing some of the information that was taken in a picture.

How does it affect our life?
If you want to operate your home greenscreen studio you should only use chroma key screen colored green. Losing information makes the stage of keying more difficult in the post production process.

The only time you will not use green chroma key screen in your studio will be only when it is vital that your talent has to wear green in the scene, or if they have light green eyes. As I have said this will be the only time you will use a blue screen. Otherwise you could end up getting our talent eyes keyed out in post production, which would end up in the video, looking like two holes straight through the head.

Make sure your talent will always avoid wearing anything green standing in front the chroma key screen. DV compression method used in video cameras throws away a lot of important colors. These colors are needed when you are trying to achieve a clean key in the post production process. In the process of compression more blue color then green, is thrown away, that makes green easier to work with.

Green chroma key screen is a lot more forgiving than blue simply because bluer gets thrown away by the in-camera compression codec, hence blue does not have as much information to work within the post production.

Conclusions
Green is the favorite color choice for shooting your video on DV formats.

In the world of DV and chroma key screen, the color green is sampled more than blue, and we get more data to work within the stage of post production.

The sample we get with blue color in DV world is far less sampled. It makes the keying difficult because we are getting a poorer choice.

If you use the green chroma key screen you will be able to perform good keying process, and it will give you smoother edges in post production.

To get a decent key using chroma key screen you should have good lighting work.

GreenScreen Studio – How Does Video ChromaKey Works

What is exactly Video Chromakey?

The word 'Studio' or 'video chromakey' for some of us rings the ball of big hall and changeable big decoration set in the background. Not any more with green screen studios. No need for building changeable sets and different backgrounds, green screen studio is a film set with only one screen.

The video chromakey method allows digital artists to display an image onto that screen creating any sort of background the production wants. The color of the screen is clear green with no design or any thing else.

In movies video chromakey screen is used as a backdrop to get the picture of the actor in front of a dynamic background with no need to get out of the studio and it all seems like in reality. Using this technology the actor has only stand in front of the green screen and the film editor will present him in anyplace the director will ask him. If the job is done properly there is no chance you will see the difference. With that modern technology the possibilities are endless and it is impossible to create a movie without a green screen studio.

Here are some examples for using video chromakey in everyday life:

1. TV Production.
You can watch daily green screen studios in action, every news show and weather reports are done with the technology. The weather reporter usually stands in front of a green screen and the animated map is shown right behind him.

2. Instructional Videos.
Instructional videos are usually boring to look at. Having an actor demonstrating the subject while actually he is standing in front of a green screen makes video chromakey more exotic.

3. Film creation.
The commonest use for video chromakey is in film or pictures. Most pictures we know, science Fiction in nature have a tendency to at least have a couple of scenes filmed in a green screen studio.

The difficulties with using green screen in straightforward videos are:

A. Creating video chromakey with green screen takes more time to edit the video.

B. It is tougher for actors to get around using only his imagination and not having something visual to relate to.
