Expression to make texts grow in size

[Othman Ahmed]

Try Something like this might help

endSize = effect("Slider Control")("Slider");
endTime = effect("Slider Control 2")("Slider");
t = linear(time,0,endTime,1,endSize);
x = text.sourceText.style.setFontSize(t);

The only think I can think of would be to add a Scale Animation and set the Scale amount to your maximum size, add an Expression Selector (you can then delete the Range Selector) and add a Tracking property to the Animator so that tracking increases as the scale goes up. You might need to fiddle with the Expression Selector’s Amount expression if you don’t like how the size progresses from small to large.

An alternative approach would be to add a scale animator, select the desired line with a range selector and keyframe the scaling. Make sure to change the text layer’s anchor point grouping to line. Then adjust leading in the character panel or add a line spacing animator afterwards

You could then apply this expression to the animator’s scale to avoid setting keyframes:

t = time - thisLayer.inPoint;
v = t * x; //replace x with percentage you want to scale every second
[value[0] + v, value[1] + v]
