Facebook invented a new time section called a ‘flick’ and it’s truly amazing


I was all set to dislike a “flick,” a time section only recently invented by Facebook (technically a Oculus team), since we suspicion it was going to be something meaningless like “the normal time someone looks during a post.” In fact it’s a unequivocally crafty approach of dividing time that theoretically could make video and audio prolongation most some-more harmonious.

So what is a flick? A crack is one 7 hundred and 5 million 6 hundred thousandth of a second — 1/705,600,000 if we cite a digits, or 1.417233560090703e-9 if we cite decimals.

And since is that useful?

As a hint, here’s a list of numbers into that 1/706,600,000 divides evenly: 8, 16, 22.05, 24, 25, 30, 32, 44.1, 48, 50, 60, 90, 100, 120. Notice a pattern?

Even if we don’t work in media production, some of those numbers substantially demeanour familiar. That’s since they’re all framerates or frequencies used in encoding or display things like films and music. 24 frames per second, 120 hertz TVs, 44.1 KHz representation rate audio.

Many of these fractions solve into untimely decimal series, necessitating shorthand or estimations. For instance, a 1/24th of a second around that a whole film attention is formed on is equal to 0.0416666666666666… on and on perpetually (even attempting to use nanoseconds to paint these durations ends adult formulating fractions of nanoseconds). So it competence be shortened for preference to 0.04167. Easier to remember, yet not numerically exact, and who knows when that “extra” value competence mangle something?

On a other hand, regulating flicks roughly all these critical fractional frequencies spin into a good accurate round numbers, no bars or determination needed: 1/24th of a second, for instance, is 29,400,000 flicks. 1/120th is 5,880,000 flicks. 1/44,100th is 16,000 flicks.

Those numbers competence not be easier for you to remember, yet it creates them a heck of a lot easier for systems to compare with one another though formulating some kind of inter-format fragment that has to be resolved with nonetheless another adjusting frequency. Computers adore whole numbers, and so do I.

Even a uncanny NTSC numbers in use due to certain technical constraints order nicely. 23.976 (technically 24*(1,000/1,001)=23.976023976230 with a final 6 digits repeating) becomes accurately 29,429,400 flicks. It’s a same for 29.97, 59.94, and any others like them. No some-more fractions or decimals indispensable whatsoever! How good is that?!

I don’t know since this is so immensely gratifying for me, in a “things wise ideally into other things” way. Probably since carrying dabbled in video and audio modifying and effects, timing and support rate things was always a pain (though thankfully we’ve mostly left behind interlacing and other bequest cruft) and we would acquire harmonization unequivocally of any sort. we honour this group of talent self-starters for anticipating this extraordinary series and formulating this potentially super-useful time unit.

You can download, fork, or differently examine a flicks format and formula over during GitHub.

(Apologies for a meme lead picture yet it’s tough to illustrate units of time.)
