Hm, I get “Error: SyntaxError: Invalid or unexpected token” on row “t = time – inPoint;”.

Okay, I got it working. I added this to the source text:

Speed = 40
StartAt = inPoint
X = text.sourceText;
T = time * Speed – StartAt * Speed;
if (T>0) X.substr(0,T)

And your script to the expression selector for the opacity animator:

spd = 40;
d = textTotal/spd;
t = time – (outPoint – d – thisComp.frameDuration);
i = t*spd;
textIndex-1 >= i ? 0 : 100

Is this the best way to do it? 🙂

Wow, that works fine to make it disappear! Thanks! Can you also help me add something that “types” the text at the inpoint in the same expression?

Thanks for your answer! I forgot to add why I don’t want to use keyframes. The thing is that I am creating an essential graphic (.mogrt) and I want the speed of the animation to be the same independent of the amount of characters.

If I do it that way, each letter will appear very fast for long words, and slow for short words.
