Google Flow
Google Labs' video workspace, built on the Veo models. It folds still-frame generation and motion into one interface, with two functions carrying the work: frames to video, where you supply a start frame and an end frame and Flow builds the passage between them, and ingredients to video, where several reference images drive the characters, objects and style of the resulting scene. Access runs through a Google AI subscription, Pro and Ultra plans.
Strengths
- Stills and interpolation in one interface, with no file round trip between two services
- The start-frame to end-frame function builds the passage without you describing what happens in between
- Reference images let you hold characters and style steady across several shots
Limitations
- A consumer subscription is required, with no programmatic access, so nothing to wire into an automated chain
- Availability and plans vary by country, which makes a recipe hard to pass on as is
- A fast-moving lab product whose functions get renamed from one model version to the next
Best for
- The first animated pass on a showcase page, before deciding whether the motif deserves a pipeline
- A designer who wants the transition shot without assembling a multi-service generation chain
- Showing a motion intent to a client before committing motion budget
