Summary  
This chapter explains how to extend a short clip by interpolating and blending its first and last frames to generate smooth intermediate frames.

General domain of usage  
Video production and animation

Two features help you go beyond a single short clip:



**Extend** — continues a generated clip for a few more seconds, keeping the same style and motion, instead of starting a new prompt from scratch.

**First and last frame** — a feature where you give Veo a starting image and an ending image, and it generates a smooth transition between them, complete with audio.

Definition


**Example use case:** Supply a photo of a closed door as the first frame and the same room with the door open as the last frame — Veo generates the door opening.


Chain a few "Extend" clips together in the Flow timeline instead of writing one long prompt — shorter, focused prompts render more reliably than one prompt trying to cover 20+ seconds of action.

Note

AI video generation has moved from novelty to everyday creative tool — and Google Veo 3.1 is currently the most capable model you can access for free. This mini-course teaches you to go from a blank prompt box to a finished, publish-ready video clip. Across 10 short lessons, you'll learn to write prompts that actually work, generate built-in dialogue and sound effects, keep the same character consistent across multiple shots, and export the right format for YouTube, TikTok, or Instagram. No editing software or technical background required — just a browser and an idea.
