Scripting: shift markers from selected layers random within values
Hi there!
Have been trying to shift markers from a bunch of selected layers, and all ok, but when I try to add some randomness to the shifting, the markers of all the layers move the same amount of frames. I’d need the markers to move random within a min max, but having each layer a different shifting, so if these are 2 layers with 2 markers
*————*—
*————*—after running the script, I’d love to get something like:
—*———–*—
—–*———–*—-and now I get:
—*———*–
—*———*–the script is this so far:
//as seen on https://www.aenhancers.com/viewtopic.php?t=71 and tweaked a bitapp.beginUndoGroup("shiftMarkers");
var comp = app.project.activeItem;
var myLayers = app.project.activeItem.selectedLayers;
var newMarkers = new Array();
var newTimes = new Array();
var min=-3;
var max=3;
var ran=Math.floor(Math.random() * (max - min + 1)) + min;
var myLayer;for (var j= 0; j< myLayers.length; j++){
myLayer = myLayers[j];
theMarker =myLayer.property("Marker")for(var i = theMarker.numKeys; i >= 1; i--){
var markerVal = theMarker.keyValue(i);
newMarkers[newMarkers.length] = markerVal;
var markerKeyTime = theMarker.keyTime(i);
var newMarkerTime =markerKeyTime+(ran*comp.frameDuration);
newTimes[newTimes.length] = newMarkerTime;// remove original markers
theMarker.removeKey(i);
}// add new markers with new value.
for(var k = 0; k < newMarkers.length; k++) {
theMarker.setValueAtTime(newTimes[k], newMarkers[k]);}
}
app.endUndoGroup();
Any ideas? Thanks!

I think you just need to move your ran calculation:
var ran=Math.floor(Math.random() * (max – min + 1)) + min;
inside your layer loop (j).

oh! thanks!
That works, but now I have a side effect… from here
after running the script, now it seems it is not removing the old markers anymore
mmm maybe I should add another removal?

hi!
after some attempts, I think I couldn’t figure it out properly… any ideas on this? I’m a bit lost
super thanks!
