controlling keyframes

[Darby Edelen]

Something like this should work:

firstKey = key(1).time;
offset = effect("Slider Control")("Slider");
valueAtTime(time + firstKey - offset);

Although that will return an error if the property doesn’t have at least 1 keyframe. A try/catch statement could be used to prevent that error:

try{
firstKey = key(1).time;
offset = effect("Slider Control")("Slider");
valueAtTime(time + firstKey - offset);
}
catch(err){
value;
}

that’s working just fine , thank you bro , but what if you have a comped animation – for instance 2 seconds- and you want to offset and play it with expression through the time line ? I mean control the beginning with a slider on another layer.
is it possible ?

Time remapping is the easiest way to do something like that. In that case an expression would be optional depending on how you want it set up.
