# YouTube Thumbnail Generation via Gemini
## Overview
Generate custom YouTube thumbnails using Google Gemini's image generation (Pro mode). Each thumbnail is a 1280x720 image with bold text overlays, thematic visuals, and branding.
## Step-by-Step Workflow
### 1. Gather Video Info
For each video that needs a thumbnail, collect:
- **Title** (already set on YouTube)
- **Content type**: "AI in Action" weekly jam or "Paper Club" reading
- **Topic summary**: What was presented/demoed (from frame extraction or title)
- **Presenter name** (optional, for subtitle text)
- **Date** in `D Mon YYYY` format
