Omni is for rough ideas. Flow is for repeatable videos.
Google just released two video tools at I/O. They sound similar. They’re not.
Gemini Omni is for when you have a rough idea and want to see it moving.
Upload a sketch. A drawing. A photo. Describe what should happen, and it generates a video from that. You can edit it by just talking to it. “Make it more cinematic.” “Change the background.” “Keep the character, change the scene.” It’s conversational and fast. Good for 10-second clips.
The idea is that instead of describing a scene from scratch, you feed it an existing sketch, voice memo, or clip and build from there.
Google Flow is for when you already know what you’re making and need the same character to look the same across multiple videos.
It creates what they call “Hero Seeds” — characters or products that stay visually consistent across multiple clips, solving the problem where a character’s face changes mid-video. Same face. Same style. Different script each time.
So the difference in practice:
Omni is your quick prototype tool. You have a product idea, you sketch it, you want something to show people. Done in minutes. It lives straight in your Gemini.
Flow is a separate production tool. You want 5 explainer videos with the same avatar, same brand look, different content each time.
Both are free.
