Move text layer X pixels on every marker
Hi, (very) long time lurker would could really use some help please:
I have a large amount of text (three paperback pages-worth), the words of which are to appear on-screen as matching narration is spoken. So far, so straightforward. However what is killing me is trying to get the text to shift up in space 1 line at the end of every line, sort of how a typewriter works. I’m trying to work out how I tell AE to move up the text precisely X number of pixels every time a marker is added. So, if my text leading is 26 points, AE knows that at every marker, 26 pixels is added to the text layers Y value. I hope that makes sense, thanks for reading and big thanks to whoever can help. -

I’d start with something like this:
leading = text.sourceText.style.leading;
m = marker;
n = 0;
if (m.numKeys > 0){
n = m.nearestKey(time).index;
if (time < m.key(n).time) n--;
}
y = n*leading;
value - [0,y] -
Have you though of just using the captions tool in Premiere Pro or even the credits roll feature? Both would give you similar effects and they’re built in as standard…

No good Tom, it has to be more flexible due to timing of the underlying VO.

Thanks Dan, any idea why I’m getting an expression error on value – [0,y] – Error couldn’t return result into numeric value ?

Hmmm… It works fine for me. It’s a position expression. It would complain if you’ve separated dimensions, but I think it would be a different error. Can you post a screen shot showing the expression?

Dan, it was me being an idiot and placing the code in Source Text rather than Position and now it works perfectly! May I ask, is it much more complicated to make each line smoothly move up over, say 6 frames? I really appreciate your help.

A little more complicate, but not much:
easeFrames = 6;
s = text.sourceText.style;
leading = s.autoLeading ? s.fontSize*1.2 : s.leading;
m = marker;
n = 0;
y = 0;
if (m.numKeys > 0){
n = m.nearestKey(time).index;
if (time < m.key(n).time) n--;
}
if (n > 0){
t = time - m.key(n).time;
easeDur = framesToTime(easeFrames);
y = (n-1)*leading + ease(t,0,easeDur,0,leading);
}
value - [0,y] -
Magnificent!

Thank you for solving this, Dan!
