What You'll Walk Out With

You leave with a character built,
not with a to-do list.

  • A reusable AI character set up in your own Flow account, ready to reuse
  • The map, so you stop confusing Omni, Veo, Flow, Agents, and Avatars
  • The one move that makes the same character show up across every clip
  • Your starter cast and which character to build next
02 · The promise
The Map, In Plain English

Omni vs everything else.

Google shipped a pile of names at once. Clear them up first, so the rest makes sense. Here's when to reach for each.

Gemini Omni Flash ← today

Google's new video model. Text, image, video, or audio in. A 10-second clip with sound out. Then you edit it by talking.

Veo

Google's specialist video model, the engine Flow is built on. Strong at generating a fresh shot from a prompt.

Flow

Google's filmmaking workspace. Where you direct scenes, camera, and keep a character consistent across shots.

Agent

The assistant inside Flow. Brainstorms ideas, tightens dialogue, organizes assets, holds your direction steady.

Avatars

A video clone of you. Record yourself once, then reuse your own likeness on camera.

@characters

How you call a saved character back into a new clip, so the same person shows up again.

03 · The map
What Is A Reusable Character

A short list of traits you lock once.

You define who they are, what they look like, and the job they do. You save it. Omni follows it whenever you bring that character back.

That's it. Same person, clip after clip.

# one character, reused everywhere @host ← the handle you call back ├─ look: 38, warm, navy blazer ├─ voice: calm, friendly, even ├─ role: workshop host └─ scene: changes every clip # look, voice, and role stay fixed. # only the scene and the line change.
04 · What is a character
The Mental Model Worth Keeping

Three layers. One stays fixed,
two change.

locked onceIdentityLook, name, and handle. This is what keeps the character recognizable. Lock it once and never drift from it.
per clipPerformanceVoice, dialogue, delivery. Same person, new line, every time you bring them back.
per clipSceneThe setting, the purpose, the call to action. The only part you rewrite for each video.

Get the identity right once, and every clip after that is fast.

How You Build One

The whole process, start
to finish.

  • 1 Decide the character's job. Spokesperson, teacher, host, customer, or ad opener.
  • 2 Describe the look in plain English, then lock it as a reference.
  • 3 Give the character a name and a handle, so you can call them back.
  • 4 Write one line of dialogue tied to a real business message.
  • 5 Generate the 10-second scene in Flow.
  • 6 Bring the same character into the next clip. Check they still look like them.
  • 7 Save the character and the prompts, then build the cast around it.

The One Thing That Matters Most

The reference decides whether
it's the same person.

Omni can make a great character once. Getting that exact character back is a different job. It comes down to one habit: lock a reference and reuse it, instead of re-describing the person every time.

Re-describe — you get a stranger

"a friendly woman in her 30s, navy blazer, hosting a workshop"

Type it fresh each clip and Omni gives you a new face every time. Close, never the same.

Reuse — you get them back

save one clean clip as @host, then: "@host, same look, new line"

Calls the saved character. Same face, same voice, clip after clip.

07 · The reference
Live Demo

We'll build the AI Spokesperson together.

It does one thing. It gives you a consistent presenter who can introduce your offer, event, or lead magnet, and then show up again across your promos.

Build the character once. Reuse it for the launch, the reminder, the replay, and the next campaign.

08 · The demo
Demo · Step 1

Nail the character before
you make a single clip.

Most people skip this and prompt straight into a video. Then nothing matches. Decide who this person is first, on paper, in plain words. Tell Omni:

What you tell Omni
"Create a consistent video presenter for my brand. Mid-30s, warm and direct, navy blazer, plain studio background. Calm voice, talks like a real person, not a salesperson. I'm going to reuse this exact person across multiple short videos, so keep the look simple to repeat."

You get one clean take. That take becomes the reference for everything after it.

09 · Demo step 1
Demo · Step 2

Lock it as a character you can call back.

Save the take you liked. Give it a handle and write down the parts that can't drift: look, voice, role.

No editing. No timeline. The character sheet is the reusable asset.

@host look: mid-30s, navy blazer, plain studio background voice: calm, warm, even, no hype role: introduces offers, events, lead magnets # reuse rule always call @host by handle. never re-describe the face.
10 · Demo step 2
Demo · Step 3 — The Payoff

Run the before-and-after.

Same job: introduce the workshop. First with a fresh prompt, then by calling the saved character.

No reference

A new face, a new vibe, a different energy. Three clips that don't look like they came from one brand.

Looks like three different people read your script.

@host reused

Same presenter, same look, same voice. Three clips that clearly belong together.

Now it looks like one show with one host.

That match is the moment it clicks.

11 · Demo step 3
Demo · Step 4 — The Consistency Fix

Character drifting clip to clip?
It's almost always the reference.

When the same character keeps showing up a little off, it's because you described them again instead of reusing them. The fix is one habit: stop typing the look, start calling the handle.

The line that keeps them consistent
"Use @host, the exact same person and look, with a new scene and a new line."

That one move is the difference between a cast you can reuse and a pile of clips that almost match.

12 · The consistency fix
Demo · Step 5

Save it. Reuse it. Done.

Keep the character and its best prompts in one place. From then on, every new clip starts from the same person instead of starting over.

Promo today, lesson tomorrow, ad next week. Same host, no rebuild.

Test before you trust it
Make three clips back to back with the same character. Watch whether the face holds, the voice holds, and the energy holds. If one drifts, you re-described instead of reusing. Fix that and run it again.
