Thats exactly the method I am trying to replicate.
My problem is the values I input are not representing the the pre comp.
The two comps are the same frame rate 24fps.
I have used your slider and frames to time and it kind of fixes it.
Your method showed up errors when I tried to use whole numbers as keyframes. I.e 2.00 would be blank I cant understand where it got a blank frame from.
but 2.20 would show the keyframe I wanted.
Thanks for your help I will try to continue as is but it seems to be a problem.
I will try to post a gif like yours to show my problem if it happens again.
Thanks for all the support
