No error when I do that.

>If I provided you with my .aep file, would you try to reproduce it in AE CC 16.1.3?

Sure.

I can’t reproduce your problem, but the closest version I have to what you’re using is 16.1.3. Expressions on the Outer Glow Opacity property work fine for me.

Try this for your range selector Start parameter:


spd = 10; // characters per second
n = 0;
if (thisComp.marker.numKeys > 0){
n = thisComp.marker.nearestKey(time).index;
if (thisComp.marker.key(n).time > time) n--;
}
if (n > 0){
t = time - thisComp.marker.key(n).time;
dur = text.sourceText.length/spd;
linear(t,0,dur,0,100);
}else
0


Dan

[Dan Ebberts]

Two questions– where did you apply the expression, and what’s the error message?

Dan

[Dan Ebberts]

Something like this probably:


n = 0;
if (numKeys > 0){
n = nearestKey(time).index;
if (time < key(n).time) n--;
}
540 + n*150

Henri,

I got your emails, but my replies get returned immediately with a permanent error rejection message. I’m not sure why, but I’ll post here instead.

What you’re describing is a lot trickier, because the expression has to be able to figure out how many characters were used in all the words triggered by previous markers. Not impossible, but considerably more complicated. I don’t have the time to do it right now, but maybe someone can crank it out for you.

Dan

[Dan Ebberts]

Based on your description, I think it would be roughly like this:


aud = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
period = .09;
curF = timeToFrames(time);
f = 0;
accum = 0;
curT = 0;
while (f <= curF){
curT = framesToTime(f);
p1 = aud.valueAtTime(curT);
p2 = aud.valueAtTime(curT - period);
if (p1 > p2)
accum++
else if (p1 < p2)
accum--;
accum = Math.max(accum,0);
f++;
}
accum

Assuming the expression is not throwing an error, what is the exact behavior you’re looking for?

Dan

[Dan Ebberts]

Just add this as the first line in your expression:

seedRandom(index,true);

I haven’t tested this, but give it a try:

var menu = comp(“MOGRT”).layer(“MOGRT Controls”).effect(“Position”)(“Menu”).value;
var opa = comp(“MOGRT”).layer(“MOGRT Controls”).effect(“StrokeAnimation”)(“Checkbox”).value;

(menu == 1 || opa) ? 100 : 0
