Count up Expression

[Mike Clasby]

Dan’s Universal Up/Down Clock should do the trick:

I don’t want it in a time format though, I want it just to count from 0 – 60 between two keyframes

This should help more… https://www.motionscript.com/design-guide/counter.html

In a simplified way:

startTime = 1.5; //in seconds
endTime = 5; //in seconds
startValue = 0;
endValue = 60;

linear (time, startTime, endTime, startValue, endValue)

Apply it in a text layer, in the property Source Text.

I am not with AE here, so I did not tested it, but I think it works.

Just one note – be careful using “startTime” as a variable name because there is already a layer attribute with that name. I found this out the hard way. 🙂

[Lord Scales] “startTime = 1.5; //in seconds
endTime = 5; //in seconds
startValue = 0;
endValue = 60;

linear (time, startTime, endTime, startValue, endValue)”

You can also modify this to use keyframe times automatically.


key(1).time


Should give you the time in seconds where the first keyframe of the property is, key(2).time will give you the second.

Just an addendum to that, key(1).time will give you an error if you don’t have any keyframes for that property. You should be able to try() and catch() these errors in the expression though:

(AE uses JavaScript with custom classes/methods/variables for its expressions)

for something this simple I’d just use an expression slider and pick whip to it, then animate the slider by setting 2 keyframes. Use math round or math floor to get rid of the decimals.

Math.floor(effect(“Slider Control”)(“Slider”))
