Summary  
This chapter demonstrates how to implement code that selects and applies different aspect ratio and resolution settings for media exports based on target platform requirements.

General domain of usage  
Video processing


Veo 3.1 supports multiple aspect ratios and resolutions — pick the one that matches where the video will be published.

| Platform | Aspect ratio | Notes |
|---|---|---|
| YouTube (standard) | 16:9 | Widescreen, horizontal |
| YouTube Shorts / TikTok / Reels | 9:16 | Vertical, native support in Veo 3.1 |
| Instagram feed post | 1:1 | Square |

Veo 3.1 can also upscale finished clips to 1080p or 4K before export.


Set your aspect ratio *before* generating, not after — cropping a finished clip afterward can cut off important parts of the shot.

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.
