This is a video on how to fold up your 5' by 7' green screen and put it back in the bag.
RaggyRagDale asked me to make a video on this and I am more than happy, too.
How to fold up your 5' by 7' green screen and put it back in the bag
Reversible / Flex - Blue & Green Background (150cmx200cm)
1.) Put your foot at the bottom of the green screen, right in the middle of it. Just enough to keep it from moving around. Be careful of footprints. If you can, put your foot on the black part of the band, only.
2.) Grab the top left or right corner. Pull toward you and down. This should cause it, to be on an angle.
3.) Keep turning it, in the direction that is closest to you. (left or right corner). Keep turning it, and pushing down at the same time. Make sure your foot is still holding it from moving around.
4.) Should be about 2 or 3 turns. And, you should have a circle shape. And, pull all the circles toward you.
5.) Put the circle shape in the bag and zip it up and you're done.
From Wikipedia, the free encyclopedia
Chroma key compositing, or chroma keying, is a special effects / post-production technique for compositing (layering) two images or video streams together based on color hues (chroma range). The technique has been used heavily in many fields to remove a background from the subject of a photo or video -- particularly the newscasting, motion picture and videogame industries. A color range in the top layer is made transparent, revealing another image behind. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as color keying, colour-separation overlay (CSO; primarily by the BBC), or by various terms for specific color-related variants such as green screen, and blue screen -- chroma keying can be done with backgrounds of any color that are uniform and distinct, but green and blue backgrounds are more commonly used because they differ most distinctly in hue from most human skin colors. No part of the subject being filmed or photographed may duplicate a color used in the background.
It is commonly used for weather forecast broadcasts, wherein the news presenter appears to be standing in front of a large map during live television newscasts, though in actuality it is a large blue or green background. When using a blue screen, different weather maps are added on the parts of the image where the color is blue. If the news presenter wears blue clothes, his clothes will also be replaced with the background video. A complementary system is used for green screens. Chroma keying is also used in the entertainment industry for special effects in movies and videogames. The advanced state of the technology and much commercially available computer software, such as Apple's Final Cut Pro, Pinnacle Studio, Adobe After Effects, and dozens of other computer programs, makes it possible and relatively easy for the average home computer user to create videos using the "chromakey" function with easily affordable greenscreen or bluescreen kits.
The principal subject is filmed or photographed against a background consisting of a single color or a relatively narrow range of colors, usually blue or green because these colors are considered to be the furthest away from skin tone. The portions of the video which match the preselected color are replaced by the alternate background video. This process is commonly known as "keying", "keying out" or simply a "key".
Processing a green backdrop
Green is currently used as a backdrop more than any other color because image sensors in digital video cameras are most sensitive to green, due to the bayer pattern allocating more pixels to the green channel, mimicking the human eye's increased sensitivity to green light. Therefore, the green camera channel contains the least "noise" and can produce the cleanest key/matte/mask. Additionally, less light is needed to illuminate green, again because of the higher sensitivity to green in image sensors. Bright green has also become favored since a blue background may match a subject's eye color or common items of clothing, such as jeans, or a dark-navy suit.
