How does it decide which visual goes where?

It reads the script for what each line is actually about and matches a visual to that meaning, timed to the narration beat. The alternative, keyword-matching individual words, is what produces visuals that are technically related and practically meaningless.

How is this different from the B-Roll Generator?

The B-Roll Generator sources and inserts footage. Smart B-Roll is the selection layer that decides which specific visual belongs at which moment, which is the difference between a video with visuals and a video where the visuals mean something.

Can it mix stock and AI-generated visuals?

Yes, and mixed is the sensible default. Real footage carries claims about real things; generated imagery covers abstract or conceptual material that no stock library has filmed.

What if a chosen visual does not fit?

Visuals can be swapped before publishing. A mismatched visual is worth fixing, since it is more distracting to a viewer than a plain or neutral one would have been.
