If you had images sitting in a Whisk library, they are gone. Google deleted anything
that wasn't migrated before the cutoff. Credits carried across by themselves, so there
was nothing to do on that side. Flow hasn't launched everywhere, which caught out people
in countries where it still isn't offered.
The three-input idea survived the move intact — you still hand it a subject, a scene
and a style. What changed is that Flow puts video generation and a scene builder on top,
so the same reference images can drive a short clip instead of a single frame.
Most of the guides on this site were written while Whisk was still standalone, and we
are working through them. Where a page tells you to open Whisk, open Flow instead — the
workflow is much the same, the address is not.
