FX Expression for Days Hours Min Sec Countdown?

[Dan Ebberts]

This should be close:


function padZero(n){
s = "" + n;
if (s.length < 2) return ("0"+s);
return s;
}
dayStart = 5;
hrStart = 0;
minStart = 0;
secStart = 0;

clockRate = 10;

totalStartSec = ((dayStart*24 + hrStart)*60 + minStart)*60 + secStart;
curTotalSec = totalStartSec - Math.round((time - inPoint)*clockRate);

curDay = Math.floor(curTotalSec/(24*3600));
curHr = Math.floor((curTotalSec%(24*3600))/3600);
curMin = Math.floor((curTotalSec%3600)/60);
curSec = curTotalSec%60;

padZero(curDay) + " " + padZero(curHr) + " " + padZero(curMin) + " " + padZero(curSec)

Thank you so much Dan!! You’re incredibly kind. This worked wonderfully. My only set back now is the rendering, but the script is exactly what I needed and it works great.

Hi, how can I change the time in this expression, say I want it to start at 05:10:15 and continue?

[Dan Ebberts]

I’m not sure what you mean exactly, but maybe like this:


function padZero(n){
s = "" + n;
if (s.length < 2) return ("0"+s);
return s;
}

hrStart = 5;
minStart = 10;
secStart = 15;

clockRate = 1;

totalStartSec = ((hrStart)*60 + minStart)*60 + secStart;
curTotalSec = totalStartSec - Math.floor((time - inPoint)*clockRate);

curHr = Math.floor((curTotalSec%(24*3600))/3600);
curMin = Math.floor((curTotalSec%3600)/60);
curSec = curTotalSec%60;

padZero(curHr) + ":" + padZero(curMin) + ":" + padZero(curSec)

Hi Dan,

Thanks so much for this expression, I am trying to use it but I’d like to connect the trim path to your expression do you think this is possible?

See screenshot

Thanks very much in advance!!

[Dan Ebberts]

I’m not sure what you’re after exactly, but this example would drive the Trim Paths End value from 100 to 0 as the seconds count down. Probably some form of this would do what you want:

t = thisComp.layer(“time”).text.sourceText.value;
sec = parseInt(t.split(” “)[3],10);
linear(sec,0,60,0,100)

Thanks for your fast feedback Dan! I dropped the expression but I am getting this error

any idea why ?

Thanks again for your time.

It might have to do with how you have the time formatted, but I can’t tell from your screenshot.
