I tried to use AI software make video girl change face, to make a new video
so I want to ask is there have software can make a women belly be big like pregnant
If can do it, I think there are many possibilities

I’ve actually wondered about this myself. I’ve seen breast expansion video edits. Im not sure what program guys are using to create the growth effect but I’m sure it can be applied to bellies in the same why it is done on breasts.

Not for consumer level. After Effects might be your best shot at something, but you're better off getting a faux belly and strapping that on a woman.
