Control speed of text tracking

[Andrei Popa]

What do you want your expression to do exactly? Because this seems bizarre. Is this applied to your tracking property? Because it increases it to 2 until it arrives to 2 seconds, then it is 0, then it grows during the last 1.55 seconds of your layer.

This is what I’m trying to accomplish. I need to do it on several similarly looking comps which have different lengths in text and durations, hence why I need it to be easy to adjust, by just extending or contracting the put point of the layer.

Thanks.

By the way, your assertion that after 2 seconds it goes back to 0 and then grows again is incorrect, after 2 seconds it continues to grow but not from 0, it keeps the tracking pace it had before.

I revised the expression to the following.
But When it reaches the fadeDur point in the layer it resets to 0, because I put valueAtTime(time) it should read the value at the current time and not go back to 0.
If anyone can help me sort this bit it will be greatly appreciated.

Thanks.

t=time;
fadeDur = 1.6;
tr=text.animator("Animator 2").property.trackingAmount

if
(t<=
(outPoint-fadeDur))
{
time*2
}
else
{
easeOut(time,outPoint,outPoint-fadeDur,tr.valueAtTime(time),30)
}
;

As far as I can tell, you can just add “time*2+” to the beginning of the easeOut line.

Thanks, Kalleheikki,

Yes, I eventually figured it out, but I placed it at the end of the line, like this:

I’m not very clear on why it works, but it does nonetheless.
Thank you for taking the time to look into this.

t=time;
fadeDur = 1.5;
tr=text.animator("Animator 2").property.trackingAmount

if
(t<=
(outPoint-fadeDur))
{
time*2
}
else
{
easeIn(time,outPoint,outPoint-fadeDur,(time*2),30)
}
;
