Google describes Flow as an AI creative studio for creating, refining, and composing videos and images. Its public feature set emphasizes scene building and manipulation, including ingredients-to-video, object insertion and removal, video extension, camera control, and asset collections.
Future Video Studio overlaps on generation, but its positioning is more production-oriented. It is built around screenplay-driven shot planning, continuity management, soundtrack and pacing coordination, transparent per-render pricing, and delivery of a finished sequence rather than a loose set of creative assets.
A simple way to think about it is this: Flow is a flexible creative canvas, while Future Video Studio is a more cohesive AI production workflow for teams that want continuity and final assembly handled in one place.
