“chained” tracking points possible?
Hello,
just wanted to ask if there’s a possibility to do something like this:
Let’s say I’ve got a piece of footage where the camera constantly moves and moves and moves to the right. Now if I wanted to track this motion, the tracking points would leave the picture of course.
So, my intention would be to have a tracking point on the right side which will of course move to the left, but a little while before it will leave the left image border, I’d like to introduce another tracking point on the right, so that I’d have two tracking points, and a few frames later, the left one would leave, but the right one would still be there, and also, when it gets near the left border, I’d like to introduce a third tracking point somewhere on the right.
That way, I’d have continuous movement. Is that possible? I know that I can “extrapolate” the movement, but that’s not perfect. And of course, I could just use several tracking points, but I’d need one continuous piece of tracking data to be able to apply it to an object.

Options:
1) If you hold down Alt (Option)you can reposition the track point but keep the same Attach Point, that should do what you want, methinks. Here’s that tut from Adobe:

2) Or apply tacking data to a Null, then apply a new track to another Null (Null 2), then parent Null 2 to Null 1… linking them up, like Andrew does here:

Andrew Kramer does exactly what you are asking in his “Set Extensions” tutorial.

Perfect!
This is exactly what I’ve been looking for. I’ll try it out immediately 😉
