IN: Chroma key compositing, or chroma keying, is a visual 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 foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. 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 the color used as the backing.

IN: Internal bleeding (also called internal hemorrhage) is a loss of blood that occurs from the vascular system into a body cavity or space. It is a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. heart, brain, stomach, lungs). It can cause death and cardiac arrest if proper medical treatment is not received quickly.

IN: Canadian law requires that all persons entering Canada must carry proof of both citizenship and identity. A valid U.S. passport or passport card is preferred, although a birth certificate, naturalization certificate, citizenship certificate, or another document proving U.S. nationality, together with a government-issued photo ID (such as a driver's license) are acceptable to establish identity and nationality. However, the documents required to return to the United States can be more restrictive (for example, a birth certificate and photo ID are insufficient) -- see the section below on Return entry into the U.S.

IN: A shoot-out is usually considered for statistical purposes to be separate from the match which preceded it. In the case of a two-legged fixture, the two matches are still considered either as two draws or as one win and one loss; in the case of a single match, it is still considered as a draw. This contrasts with a fixture won in extra time, where the score at the end of normal time is superseded. Converted shoot-out penalties are not considered as goals scored by a player for the purposes of their individual records, or for ''golden boot'' competitions.
