Expression for typewriter effect
Hi,
i am trying to figure out a way to set the speed of the typewriter animation without keyframes to be the same rate regardless of the length of the text.. so i don’t have to adjust keyframes every time i use it… is there a way to define the typing speed by “letters per frame” or something? Or any workaround for this?
I need it to write on lower thirds,, and the names are all different lengths..this would save a lot of time..
I tried to simply use the (time*) expression on the start of the range selector but that didn’t seem to work..

Something like this for the Start parameter, maybe:
charPerSec = 5;
t = time – inPoint;
(t/charPerSec)*100Dan

Thanks…
The problem is that it dosent seem to take into account the amount of characters, it just automates the 0-100 percent value of the range selector, so if i duplicate the layer and add longer text, it reads out the longer text in the same amount of time.

That’s because I left out a step. Sorry–try it this way:
charPerSec = 5;
sec = text.sourceText.length/charPerSec;
t = time – inPoint;
(t/sec)*100Dan

Sweet….
Looks like that did it… Lifesaver, thanks so much. I need to learn how to write expressions.
