Q encoder.
Similar to I encoder but responsible for different colours.
Quantisation
  1. Method of approximating the amplitude of an analog signal sample and recording it in terms of bits. The process of measuring an analog signal and assigning numerical levels to it.
  2. Rounding or truncating a value to the nearest reference value. In a sequencer, used to adjust recorded material so it will be performed precisely on a selected division of the beat. In digital audio, the range of numbers used for specifying amplitude levels of a recorded signal. (16 bit quantization = 65,536 values; 8-bit = 256, etc.)

    3. The higher the quantisation, the higher the quality of the sound.
    Inadequate quantisation usually results in a ‘buzzing’ noise.
Quantization Resolution.
The accuracy of measuring an analog signal and representing its strength with numbers. A two-bit resolution describes something by 4 levels, a three-bit resolution, 8 levels.
Quicktime Movie.
A file format that takes a series of individual files (pictures) and combines them into one file and can play them in sequence, creating animation or motion.
