YouTube first 30 seconds engineered for maximum retention (with re-hooks by content type)

Act as a YouTube strategist who obsesses over retention graphs. You know that YouTube's algorithm weighs the first 30 seconds more than any other segment — but within those 30 seconds, the first 3 seconds matter more than the next 27. A viewer's thumb is still hovering over the back button. Your job is to make it stay.

Retention psychology you MUST apply:
- THE FIRST 3 SECONDS: This is the 'pattern interrupt' window. The viewer just clicked from a feed of thumbnails — their brain is deciding 'did this match my expectation?' You need VISUAL + AUDIO novelty simultaneously. No logo intros, no 'hey guys', no channel branding. Start mid-action, mid-sentence, or with an unexpected visual.
- SECONDS 3–10: Deploy the CURIOSITY GAP (George Loewenstein's theory) — create a gap between what the viewer knows and what they want to know. State a surprising claim, show an unexpected result, or pose a question they can't walk away from without the answer.
- SECONDS 10–30: Earn the right to keep them. Quick credibility (why should they listen to YOU?), a concrete promise ('by the end of this video, you'll know exactly how to...'), and an OPEN LOOP — tease something coming later that they'll miss if they leave.

For a video about [TOPIC] targeting [AUDIENCE], content type [TUTORIAL / COMMENTARY / STORY / VLOG], produce:

1. 5 TITLE OPTIONS (curiosity + clarity, ≤60 chars each):
   - At least 1 using a number + unexpected modifier ('7 Mistakes Even Senior Devs Make')
   - At least 1 using a 'How I...' or 'Why I stopped...' personal angle
   - At least 1 using contrast/tension ('The $5 Tool That Replaced My $500 Setup')
   - No clickbait you can't pay off in the video.

2. 2 THUMBNAIL CONCEPTS:
   - Subject/visual (what's IN the frame — face with exaggerated expression, a before/after split, a single object with context)
   - Text overlay: ≤3 words, large enough to read on mobile. Use a contrasting color.
   - Emotion to convey (curiosity, shock, transformation, 'wait what?').
   - The thumbnail must create a 'title + thumbnail = curiosity gap' combo. The thumbnail should NOT just restate the title — it should add information that makes the title more intriguing.

3. SCRIPTED FIRST 30 SECONDS with B-roll direction:
   Format each line as: [TIMESTAMP] [VISUAL: what's on screen] [AUDIO: what the host says]
   - 0:00–0:03: COLD OPEN — no intro, start mid-action or with the most surprising moment. Include B-roll or visual direction. This is your pattern interrupt.
   - 0:03–0:10: CURIOSITY GAP — the hook line that creates the gap. State the payoff or the unexpected claim.
   - 0:10–0:15: CREDIBILITY — one quick line (not a bio — a proof point: 'After testing 47 of these...' or 'I've been doing X for Y years and...').
   - 0:15–0:25: PROMISE + ROADMAP — tell them exactly what they'll get ('I'll show you the 3 settings, the one mistake to avoid, and the template I use').
   - 0:25–0:30: OPEN LOOP — tease something specific coming later ('...but the third one is the one nobody talks about, and it changed everything').

4. RE-HOOK LINES — 3 lines to drop at likely retention dips (usually at 30%, 50%, 70% of video length). Make these SPECIFIC to the content type:
   - For TUTORIALS: 'Now here's where most people mess up...' / 'This next step saves you [specific time/pain]' / 'If you skip this part, steps 4 and 5 won't work.'
   - For COMMENTARY: 'But here's what nobody's saying about this...' / 'And this is where it gets controversial...' / 'Wait — there's a counter-argument that actually changed my mind.'
   - For STORY/VLOG: 'And then [unexpected thing] happened...' / 'At this point I almost quit, but...' / 'What I didn't realize was...'

Return labeled sections. Keep it punchy — no filler, no meta-commentary about YouTube strategy. Just the deliverables.
