Aflick is aunit of time equal to exactly 1/705,600,000 of asecond. The figure was chosen so that time periods associated withfrequencies commonly used for video or screenframe rate (24, 25, 30, 48, 50, 60, 90, 100 and 120 Hz), as well as audiosampling (8, 16, 22.05, 24, 32, 44.1, 48, 88.2, 96, and 192 kHz), can all be represented nicely withintegers.[1] That is useful in programming, because non-integer computing generally involves approximations, and possibly leads to noticeable errors.
A flick is approximately 1.42 × 10−9 s, which makes it larger than ananosecond but much smaller than amicrosecond.
The unit was launched in January 2018 byFacebook.[2] A similar unit for integer representation of temporal points was proposed in 2004 under the name TimeRef, splitting a second into 14,112,000 parts.[3] This makes 1 TimeRef equivalent to 50 flicks.
The wordflick is aportmanteau offrame (as in e.g. animation frame) andtick (as in computer instruction cycle).[2]
