track born to video?

track layer to video
can copy coordinates to a layer, but can't you copy track coordinates to a bone like
track born to video?

You could place the root bone of a bone layer exactly on the origin point, then track that layer to a video.

And then menu: Bone>Track Bone to Video, and select the tracking point for the bone to follow. This keyframes the bone.

You can then copy these bone keyframes to any other bone, if needed.

Thanks for the answer

I wanted to use the tracking data for only the second point of the line, but I couldn't do that.
I thought it would be nice if the tracking data could be used for bones.

I'm not sure what you mean by "only for the second point of the line."
You could have one vector point unbound and the other on the line bound to a video tracked bone.

You can also track the base and tip of a bone to two different tracking points... that can rotate and even scale the bone.

I didn't know this command existed.
I believed it could only be applied to layers.
I'll re-read the manual.
Thank you so much.
