I just can imagine to do this with expressions, or i am missing something.
Three layers composition: at the point the first one finishes, second one begins,
at the point the second one finishes, third one begins.
I need to drag the second one along timeline so that
its In point and Out point slide the Out point of anterior and the In point of posterior one.
Ever keeping it between the other two ones,
without have to reassign their In and Out points.
Thanks in advance.
