  Fade in and out on each marker

  Posted by Andrei Popa on October 10, 2018 at 5:06 pm

  I need an expression that i thought would be simple but it seems i can’t get it. I want the opacity to go 0-100 in 10 frames, hold 10, fade out in 10. And all these before each marker.

  Basically the animation starts one second before each marker, split in 3. Fade in, stay, fade out. And stays zero for the rest of the duration.

  Try this:

  
m = marker;
n = 0;
if (m.numKeys > 0){
n = m.nearestKey(time).index;
if (m.key(n).time <= time){
n++;
if (n > m.numKeys) n = 0;
}
}
if ( n > 0){
t = m.key(n).time - time;
if (t > .6667){
linear(t,.6667,1,100,0);
}else if (t > .3333){
100;
}else{
linear(t,0,.3333,0,100);
}

  }else
0;
