Green Screen In TV Production: Using It Effectively
The advent of satellite television has seen the virtual explosion of TV channels, broadcasters, production houses and content producers. This is because cable TV and direct to home platforms have indeed pushed the frontiers of television broadcasting beyond all conceivable limits and onto a global scale. It is no wonder that TV networks across the globe utilize the use of a Green screen.
One of the common techniques that are used in television program production is that of using a Green screen in the background of the studio where a particular programme is being shot. This is part of the technique of chroma key which deals specifically with the removal of certain images in the background of the shot and superimposing this with some other image, which is more suitable for the production. For instance, one can use a screen that is green in colour behind a broadcaster who is reading out the weather news. When viewers watch the programme, the green or blue screen as the case may be, is replaced with a weather map or scenes of certain cities or satellite images being shown instead.
A Green screen is particularly useful for chroma key uses, on account of the fact that the normal human skin tone has very little elements of green in it. This helps in superior quality of image superimposition as well as the replacement of background, without interfering much with the general view of the broadcaster who is standing in the foreground. If there had been any green tint or tone in human skin, parts of the body would have become invisible when using the other coloured screen, making the effect quite odd and extremely inappropriate and incongruous.
One of the main advantages of using a Green screen is that it is fairly easy to implement as well as being cost effective. If one were to use a huge plasma or HDTV screen behind the broadcaster, the effect could be marvellous, but the cost would be far greater than using a green screen. In these days of economic downturn, where cost management is the key, the dice is loaded in favour of using cheaper options.
One can easily make a Green screen that can be used in TV programme production. For this, something as simple as a table cloth can be used. This cloth has to be uniformly painted, so that there are no smudges or uneven areas that would stand out when the show goes on air. One can also use a plain wall that is evenly painted in green to form the coloured background. One of the tips to remember when using such a screen is that if the background image is one of trees or forests, green is a more suitable colour to use than blue for the background, while if the image is of the sea or the sky, green would not be so apt. Using a green screen is thus an effective means of utilising chroma key technique in TV programme production, which is popular due to its simplicity and inexpensiveness.
What color should I use for Chroma Key photography?
Green and Blue seem to be the colors. Anyone had any experience with this? Is there any advantage of one over the other?
I've had some problems with blue eyes on the blue, so I prefer that obnoxious shade of green.
Overlaying video on encrypted HDMI connections (Hackaday)
[bunnie] is up to his old tricks again. He successfully implemented a man-in-
the-middle attack on HDCP-secured connections to overlay video in any HDMI
video stream. There's a bonus, too: his hack doesn't use the HDCP master-key.
It doesn't violate the DMCA at all. HDCP is the awful encryption scheme that
goes into HDMI-compatable devices. Before [...]
