Summary  
The chapter explains how to balance resource consumption and output fidelity by using a fast, low-cost mode for prompt refinement and a quality-focused mode for generating final AI outputs.

General domain of usage  
AI video generation


Flow gives you a daily credit allowance (around 50 AI credits, roughly 12 videos a day on paid plans). Every generation uses credits, so it pays to know when to spend them.

### Use Fast mode when...</summary>
You're still testing and refining your prompt wording. Most good results take 3–5 attempts with small tweaks.


### Use Quality mode when...

You've already found a prompt you're happy with in Fast mode and are generating your final, keepable version.





Running Quality mode on every single draft is the most common way creators burn through their daily credits.

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.
