Thanks so much Mark!!! Very very helpful!! I’ve got what I needed. But I’ve made some slight edits to the expression. Below is the one which I’ve used. Thanks so much!!!!
startFrame = thisLayer.marker.key("1").time ;
timeOffset = -1*comp("Contorls").layer("Contorls").effect("Animation Offest (Speed)")(1);
ease,ease (t=time, startFrame-timeOffset, startFrame, 0,100)
