TL;DR

Long AI video creation comes down to one repeatable loop. You write the prompt in Claude Fable 5, generate in Google Flow, and extend by confirming the last frame before adding new action.

This guide walks through building a character sheet, generating a first clip, and extending it step by step.

It covers the exact prompt pattern that keeps a character's face and outfit consistent across clips. It also covers how to fix broken continuity when a scene loses context.

Key points

  • Gemini Omni Flash generates roughly 10-second clips per segment.

  • The most common mistake: skipping the confirmation step and jumping straight into new action.

  • Attach the same character reference images on every extend, even after several clips.

Introduction

For a while I quit on long AI videos. The character kept drifting, and stitching mismatched clips felt like a waste of time.

Suddenly, Fable 5 came back online. Then I moved one job over to Fable 5, and Google Flow finally had something consistent to follow.

Now I know why people hyped over Fable 5 that much.

The method I use today works for any story you want to tell. You won't need to rely on one lucky prompt to get it right. Every step is laid out clearly, and you just follow them in order.

→ I'll walk you through each step with Claude Fable 5 and Google Flow to turn them into images and video. Like this:
