🎬 Creating Action B-Roll with AI Video Generation Tools(Sora 2 / Veo)with example Prompts



🧩 Introduction

Action B-roll is what makes your YouTube video feel alive. Instead of just telling viewers what’s happening, you show them.

Thanks to AI video generation tools (like Sora 2, flow+Veo), creators can now easily generate cinematic, realistic, or even stylized B-roll without filming a single frame.

In this guide, we’ll walk through several common examples of Action B-roll — and show how you can use AI tools to bring each one to life.

All prompts in this article have been tested and are compatible with Veo / Sora 2.
