A line move with two tracked point ?

Hello,
I have two tracked points and they are moving differently during my video clip.
I want to put a line and use this two points like my line's extremeties.
Then, my line length and her orientation changes with the movments of the 2 points.
It is possible to do this effect with motion5 ? If yes how ?
I think to "attached" the line's extremeties to the tracking's point....

Yes it can be done, I'm 90% sure. I'm not at my edit bay now but will jump back on when I am and take you through doing it.

Great ! Thanks !

Well, I may be wrong. I can get the Anchor Point of a line to track, but not both Control Points. It seems Control Points of a Shape can't be applied to a tracker.

But I'm not giving up yet, I'm asking a couple of Motion experts I know, see if they know some trick.

At worse, you can manually keyframe each Control Point of the line Shape.

Ok, i'm waiting then...

If you haven't already solved this, the way to do it is to use a Track Points behavior on your line and then make sure you select Attach to Source (rather than the default of Mimic Source) in the Track Points/Transform drop-down menu.

The Track Points behavior is specifically designed to deal with the tracking of shapes - it can be found under the Behaviors/Shape menu in the library.

I was just coming to post that. Thanks for catching that Simon.

Problem I'm having with it is that Track 1 analyzes just fine, Track 2 won't track at all, on a straight line shape.
