Create kangaroo animation (mp4)

What would be the easiest way to capture a kangaroo animation directly into an mp4 file? I know you can animate sliders and convert the multiple png´s into an animation, but since kangaroo works on a button basis, is there a way to record a viewport which shows you the complete kangaroo animation?

Thanks in advance:)

You will have to use the Step Solver. Check the post linked below:
