That's what I think the tech at this stage cannot do. You make two clips from the same prompt with a minor change, e.g.
> a thief threatens a man with a gun, demanding his money, then fires the gun (etc add details)
> the thief runs away, while his victim slowly collapses on the sidewalk (etc same details)
Would you get the same characters, wearing the identical clothing, the same lighting and identical background details? You need all these elements to be the same, that's what filmmakers call "continuity". I doubt that Veo or any of the generators would actually produce continuity.
