# Thumbnail A/B Tester Generate 3-5 thumbnail concepts, score them, ship the winner. ## When to use - User has a video and wants 3+ thumbnail variants. - User wants critique on an existing thumbnail. - User wants to know which still frame from a clip is strongest. ## Variant generation strategy For one clip, produce variants across these axes: | Axis | Option A | Option B | Option C | |---|---|---|---| | **Frame** | Hook moment (start) | Climax (mid) | Payoff (end) | | **Text** | One word | Short phrase | None (visual only) | | **Face** | Tight crop (eyes visible) | Medium shot | Object only | | **Contrast** | Dark bg + bright subject | Inverted | High saturation | Pick one option per axis → 3-5 thumbnails total. Don't generate 30 — too much noise. ## Scoring rubric (0-10 each, sum / 40) | Factor | What to check | |---|---| | **Hook clarity** | Can a viewer read the *story* in < 1 sec? | | **Face / emotion** | If a face: is the emotion strong & specific? | | **Text legibility** | Readable at 320px wide (IG feed size)? | | **Contrast** | Subject pops from background? | ## Heuristics (the boring stuff that matters) - Faces with **visible eyes** outperform face-from-behind ~2:1 on IG. - Bright single-colour backgrounds (yellow, red) beat busy stills. - Text on thumbnail: ≤ 4 words. Beyond that, no one reads. - Avoid feed-camouflage: if your thumbnail looks like 5 others on the explore grid, it loses. ## When to NOT use a thumbnail - IG Reels cover image is shown on
