Need to control two key frames with expression
Hi CC,
Here is my first post!!!
I am doing a shape layer (trim) animation. The keyframes are set to “end” value from 0–100 (time 0–2 Seconds). Now I need to control this speed with a controller, I think I can use sliderControl for this. Any help to do this with expressions will be great.

There might be a better way, but I do this kind of thing with a marker (on layer or comp level)
Then have a slider control the time offset in seconds.Hope this helps.

endFrame = thisLayer.marker.key("MARKERNAME").time ;
timeOffset = pickwhip-the-slidercontrol ;
linear (t=time, endFrame-timeOffset, endFrame, 0,100) -
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)Anoop
