2D animation program with video background?

Question

Video

Hello. I would like to find a program in which you can create skeletal 2d animation. At the same time, on the back "layer" it would be possible to place a video in which, for example, the character does actions (runs, etc.) and then it would be possible to create animation, so to speak, motion-capture, attaching to frames))
Where- I met similar.

So far, I know only one such program: Adobe Flash .
Specifically, the skeleton is created using the Bone Tool:
There was information that this tool was removed in some version of Flash, but it is present in Adobe Flash CC 2015.
