Can you ease a text-generating expression…with an expression?
Hey everyone… bear with me here…
I am a building a Live Text template, so I would like to end up with a slice of text (which would animate on in a pretty way) that I can just quickly swap text in and out of in Premiere.
I would like it to animate from the center and stay center justified. I also have an expression that uses the SourceRecAtTime function to animate a shape layer along with the text as it animates on.
However, as near as I can tell, animating on by scale/character uses the anchor point OF THE FINAL LAYOUT, and not what is one screen at any given time.
Now, I was able to automate the characters typing on AND keep the text center justified with the following expression:
charPerSec = N;
idx = Math.floor(time*charPerSec);
value.substr(0,idx)(thank you for your 2011 post about this Dan)
…. but that doesn’t look quite right. It’s much too abrupt. I can get it to ease from the beginning by linking a slider to the “charPerSec” function, but it still hard stops at the end.
Is there any way to automate some easing of this, regardless of what and how much gets typed in?Thanks in advance for your help, any and everyone!

Try this:
charPerSec = 10;
tTotal = value.length/charPerSec;
t = easeIn(time,0,tTotal,0,tTotal);
idx = Math.floor(t*charPerSec);
value.substr(0,idx)Dan

Oh thanks, Dan! I’ll try that on Monday.
Can you break down what is going on in that for me briefly?
charPerSec = 10; –> how many characters get revealed per Second.
tTotal = value.length/charPerSec; –> something divided by the charPerSec
t = easeIn(time,0,tTotal,0,tTotal); —This string ive seen around in other threads, but I’m not sure what it all points to…
idx = Math.floor(t*charPerSec);Ya lost me
value.substr(0,idx)huh?Thanks so much, Dan. You have sent my workflow to the stratosphere over the years, so thanks so much. 🙂
