Adobe After Effects Scrolling text

[Dan Ebberts]

I’m no expert in scrolling text, but I would think you’d want the speed to be a multiple of the frame rate. You could try an upward scroll with something like this:

mult = 2;
value – [0,time*mult/thisComp.frameDuration]

There’s an Autoscroll – Vertical animation preset that adds an expression for this purpose for you.

For this and other relevant information, see “Best practices for creating text and vector graphics for video”.

Great Expression! I use, but need of a delay to expression start and a limite to end, like Keyframes. Can Help me?

I want that text begin to scroll in 5 seconds and stop in 30 seconds.

Thanks.

mult = 2;
value - [0,time*mult/thisComp.frameDuration]

[Dan Ebberts]

I’m guessing this isn’t quite right, but something like this maybe:

mult = 2;
t = linear(time,5,30,0,25);
value – [0,t*mult/thisComp.frameDuration]

Thank you, Dan!

I did something wrong? I should not make a question in the post of someone else, is it?
I’m sorry.

[Dan Ebberts]

No, I just meant that it was possible that I had misinterpreted your question.

I understand. You were right. I need one more little help.

In another application:

How to use the same expression with delay of 22 frames to start? instead of simulate keyframes.

Thanks.

mult = 2;
value - [0,time*mult/thisComp.frameDuration]

[Dan Ebberts]

Like this maybe:


tStart = framesToTime(22);
if (time > tStart){
mult = 2;
value - [0,(time-tStart)*mult/thisComp.frameDuration]
}else
value

Oh, Yeah! Thank you so much!
