Countdown Timer in AE

[Julian Sixx]

Hi
use this expression for the source text

hr = 00;
min = 00;
sec = 0;

d = new Date((((hr*60)+min)*60 + sec + time)*1000);
s = d.toGMTString();
s.substr( -12, 8 )

I believe there is actually a Time effect that will count down…

i need it to count down from 24:00:00 . . . . this one starts at 00:00:00

just did this

add a slider to a blank source text layer and then add this expression:

timeToTimecode(t = effect(“Slider Control”)(“Slider”)+ thisComp.displayStartTime, timecodeBase = 60, isDuration = false)

Animate the slider 1400.00 will give you 00:24:00:00 then just add a mask to remove the first two digits. because you change the timecode base to 60 you end up with a timer that will count in whole seconds. .1 on the slider = 6 seconds.

you can also use this expression with a slider to make a hrs:min:sec:1/100 timer bu masking out the top dot in the last column

timeToTimecode(t = effect(“Slider Control”)(“Slider”), timecodeBase = 100)

just took the basic expression from the global properties and changed the timecode base and added a slider to change the number.
