Animate multiple persons

Hi,

I'm investigating the Animations API, and found out that I can animate only one person from a photo.

If I copy each person into a separate image, and animate them one by one, I can not create a smooth video from multiple animations since the background doesn't fully match the original photo.

Could you please let me know, is there any way to animate multiple persons in a photo? Or probably there is workaround of how to create a smooth video from multiple animated faces?

Thank you.
