positioning a video between 2 null objects
it says it all right there ^^^ but here’s some more details.
i needed lines to shoot around a tracked area, and found a video of this:
https://www.youtube.com/watch?v=hnKQnl09_BA
(not a link)so, i tried it, and had some trouble because i need to do the same thing, but without the beam effect because i have my own mp4 file of an animated line.
how do i use tracking, null objects, and expressions do do this?thanks for the quick response
(im still at an introduction level for expressions, so take it easy, but am experienced with everything else, like basic compositions, tracking, utilizing parenting, etc…)-jon

If you just need the center point of 2 Null Objects:
n1 = thisComp.layer("Null 1").transform.position;
n2 = thisComp.layer("Null 2").transform.position;
pX = (n1[0] + n2[0]) / 2;
pY = (n1[1] + n2[1]) / 2;
[pX, pY]

that did the job, thanks.
