FTP (File Transfer Protocol) — common Internet protocol used for transferring files between
computers.
Gamma — curve that describes how the middle tones of images appear. Often confused with
brightness/contrast, gamma is a non-linear function. Changing the value of the gamma
affects middle tones while leaving the white and black of the image unaltered. Gamma
adjustment is commonly used to compensate for differences between Macintosh and
Windows video cards and display.
Gamut — range of possible colors within a given color space. For example, the gamut of NTSC
is dramatically more limited than the gamut of the RGB color space.
Generation Loss — image degradation that occurs each time a movie is saved with a lossy
compression codec. Also occurs in each dub with analog video tape.
GOP (Group of Pictures) — self-contained sequence of MPEG frames starting with an I-frame,
followed by B-frames and P-frames and ending with a I-frame.
