Innovate with Green Screen!

(View Complete Item Description)

Chroma key composting, or chroma keying, is a special effects / post-production technique for composting (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 news casting, motion picture and video game 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, color-separation overlay (CSO; primarily by the BBC[2]), 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.[3]

Research shows that maintaining high retention rates in distance learning education is a challenge. There are various tools and resources available web-based tools that can help identify at-risk students and measure and boost opportunities for growth and success. Students can take advantage of these resources to prepare ahead of time to ensure a "SMART" start and successful completion of their online course work. First we will review SmarterMeasure to identify attributes, skills and knowledge and assess competencies necessary for successful distance learning and help identify potential resources to help maximize efficiency in potentially deficient areas. Then we will review SMARThinking that helps educational institutions offer students outstanding academic support through a network of professionally certified educators focused on increasing student achievement and enhance learning.
