Hi there,

I'm trying to time remap a loop I have in a Pre-comp so that in the main comp it start always when the time cursor hit a layer marker.
Basically I need strech the duration of the Pre-comp so that it always fit the distance between two layer markers.

I tried Dan Ebberts' express:

hit=marker.key(1).time;
t=time-this_comp.layer("audio.wav").marker.nearest_key(time).time;
t+hit

but the loop stop at half time of the animation.
I think because the time cursor as soon as it cross half of the loop is getting the value of the next layer marker.
I also try to add some statement but with no luck..
Does anybody have any idea?

Try this one. It should get you close. Change "marker layer" to the name of your layer where the markers will be.

L = thisComp.layer("marker layer");

p = 0;
if (L.marker.numKeys > 0){
p = L.marker.nearestKey(time).index;
if (L.marker.key(p).time > time){
p--;
}
}

n = 0;
if (L.marker.numKeys > 0){
n = L.marker.nearestKey(time).index;
if (L.marker.key(n).time <time> L.marker.numKeys) n = 0;
}
}

if ((p == 0) || (n == 0)){
inPoint
}else{
linear(time,L.marker.key(p).time,L.marker.key(n).time,inPoint,inPoint + source.duration)
}

Yikes! The forum formatting trashed my code. Let me try it again:

L = thisComp.layer("marker layer");

p = 0;
if (L.marker.numKeys > 0){
p = L.marker.nearestKey(time).index;
if (L.marker.key(p).time > time){
p--;
}
}

n = 0;
if (L.marker.numKeys > 0){
n = L.marker.nearestKey(time).index;
if (L.marker.key(n).time <= time){
n++;
if (n > L.marker.numKeys) n = 0;
}
}

if ((p == 0) || (n == 0)){
inPoint
}else{
linear(time,L.marker.key(p).time,L.marker.key(n).time,inPoint,inPoint + source.duration)
}

Dan, in case you don't know this, you can use the "code" tags to keep clean code formatting on the forum
