Audio levels triggered by markers

[Dan Ebberts]

It looks like when n is 0 (before the first marker) L1 is not defined so this line will fail:

}else{[L1,L1]}

Hello Jean Livenais

NOTE- Not all error code is nothing

It might be pointing you to the way forward but if you can decode it , you can be pixee of or even fed up

Have finally decided and solved it for you with the meaning of each which will help you understand how to solve the errors

Kindly read through carefully

Answer is
“n=0;

m=thisLayer.marker;

//fadeTime = framesToTime(fadeFrames);
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;
if (m.key(n).value)
{

fadeFrames = m.key(n).duration;
L1 = eval(m.key(n).comment.split(” “)[0]);//-50;
L2 = eval(m.key(n).comment.split(” “)[1]);//-12;
v = linear(t,0,fadeFrames,L1, L2);}
else{
v = linear(t,0,fadeFrames,L2, L1);
}
}else{[L1,L1]}
[v,v]”

This code, which calculates a marker’s value based on its parameters at a particular time, was built in the scripting language of Adobe After Effects.

Two variables, n and m, are initially initialized in the code. Whereas m is given the value of the marker for the current layer, n is given the value of zero.

Then, it determines whether the marker contains any keyframes. If it does, it uses the nearestKey() method to identify the keyframe that is the closest to the current time (in seconds) and assigns its index to the variable n.Answer is
“n=0;
m=thisLayer.marker;

//fadeTime = framesToTime(fadeFrames);
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;
if (m.key(n).value)
{

fadeFrames = m.key(n).duration;
L1 = eval(m.key(n).comment.split(” “)[0]);//-50;
L2 = eval(m.key(n).comment.split(” “)[1]);//-12;
v = linear(t,0,fadeFrames,L1, L2);}
else{
v = linear(t,0,fadeFrames,L2, L1);
}
