copy and paste vertice position

Hi.

I have multiple animations, where the scenes are identical, but the camera motions are different.

the camera moves on a path using follow path constrain

in all scenes (4) the camera starts at the same point, but have different shapes.

I want to change the starting point of the camera, and this must be exactly the same in all 4 scenes, so I must place the motion shapes first vertex in exactly the same place in all 4 scenes, how can I do this, there is a copy and paste location for vertices or something like?

Thanks, Boti

there is a cut/paste box-icon … in the fcurve-editor window
just in front of this “ghost”-icon at the end of the menu-bar (in the fcurve-editor window)
select with box (press b, drag mouse) one curve point and press the cut-icon
switch to other curve and there press paste-icon
and the point appears there at the position

or

press the n-key to let the property-window (at right side) appear
for a selectec f-curve point/vertex
and write down the values
then switch to the other curve
and there select the f-curve-point to be changed
and in the property window enter the values from the other point.
