Before you start

Tools used

Step by step

The workflow

Follow the sequence once, then adapt the prompts, checks, and handoffs to your own setup.

4 steps

Step01

Brainstorm with the AI Director

Use the chat feature in Google Flow to brainstorm a storyboard. Start with a broad request for scenes. The AI will ask clarifying questions about the setting, tone, and visual style. Answer these to refine the concept and get a detailed, multi-scene storyboard.

Example prompt
help me create a storyboard for a hype video. For the How I AI podcast, I already have a character. Named me, we can reference, help me come up with the few scenes that would make this great. This is a podcast by Claire about the best ways to use AI at work and in life.!
Step02

Generate Video Scenes

Copy each scene description from the storyboard and paste it into the video generator. If you are using a custom avatar, replace character names with the @me tag. Before generating, confirm the tool is set to video mode, not image mode. The model will return multiple video options for each prompt, allowing you to choose the best take.

Example prompt
I spin my ergonomic chair around to face the camera. I push my glasses, which I don't have up to the bridge of my nose, and I say, 'I'm Claire and this is how I AI.'
Step03

Assemble the Final Cut

Open the built-in video editor in Google Flow to assemble the final cut. For each scene, select your preferred video clip and drag it onto the timeline. Arrange the clips in the sequence outlined by your storyboard.

Step04

Trim and Finalize

Make final adjustments directly on the Google Flow timeline. Trim the start and end of each clip to control the pacing and adjust transitions between scenes. No external video editing software is required.

What good looks like

  • Storyboard includes distinct scene descriptions
  • Video generator returns multiple clips per scene prompt
  • Timeline contains clips arranged in storyboard order
  • Final export has trimmed transitions and consistent pacing

How to recover when the loop fails and where human judgment helps.

Recover

If it goes sideways

Scene generation runs in image mode instead of video mode
Confirm the generator is switched to video before rendering
Avatar prompts fail to reference the custom character
Replace character names with the @me tag in each scene prompt
Clip pacing feels inconsistent after assembly
Trim scene boundaries and adjust timeline ordering before export
