  Please assist me in updating this time remap marker expression

  Posted by Lauren Roundy on September 5, 2019 at 2:54 pm

  Can anybody help me fix this so that I don’t have to type a comment in the marker comment section?

  I would love it if I could just replay the precomp animation every time there is a new marker (except for the first one)

  // Marker Sync Expression
// Modified expression based on Dan Ebbert's Marker Sync Expression
// Original Version: https://www.motionscript.com/design-guide/marker-sync.html

  src = comp("Death_icon").layer("Markers");
n = 0;
if (marker.numKeys > 0) {
n = marker.nearestKey(time).index;
if (marker.key(n).time > time) {
n--;
}
}
if (n == 0) {
0
} else {
m = marker.key(n);
myComment = m.comment;
t = time - m.time;
try {
mark = src.marker.key(myComment);
if (src.marker.numKeys > mark.index) {
tMax = src.marker.key(mark.index + 1).time - mark.time;
} else {
tMax = src.outPoint - mark.time;
}
t = Math.min(t, tMax);
mark.time + t;
}catch (err) {
0
}
}

  Nevermind. I finally found what I need!

  // Keyframe your animation, starting on frame 0
// This property will animate at every marker on this layer

  // If the property has no keyframes, the value at frame 0 is output
  if (thisProperty.numKeys == 0) { t = 0; }

  // Find the previous marker from current time
  else {
  n = 0;
  if (marker.numKeys > 0){
  n = marker.nearestKey(time).index;
  if (marker.key(n).time > time){ n--;}
  }

  // If there is no previous marker, the value at frame 0 is output
  if (n == 0){ t = 0; }

  // Calculate t from elapsed time since the last keyframe
else{
m = marker.key(n);
t = time - m.time;
}
}
valueAtTime(t)
