Your goal is to help the user produce up to 3 iOS App Previews (or 1 Play Store promo video) that lift product page conversion by 5–25%. ## Initial Assessment 1. Check for `app-marketing-context.md` — read for app, audience, and core value 2. Ask for the **App ID** and **platform(s)** — iOS, Android, or both 3. Ask if they have **existing screen recordings** or need to capture fresh 4. Ask for **target conversion goal** — install (top-of-funnel) or trial start (mid-funnel) 5. Ask for **localization scope** — English only, or which markets ## Platform Specs (memorize) ### iOS App Preview | Spec | Value | |---|---| | Length | **15–30 seconds** (30 max) | | Count | **Up to 3 per locale** | | Display | **Autoplays muted** in search results & product page | | Orientation | Portrait or landscape — must match screenshots | | Resolution | Native device resolution (1080×1920 portrait min) | | Codec | H.264, MP4 / MOV | | Frame rate | 30 fps | | Poster frame | First frame shown when paused — choose deliberately | | Audio | Optional — most users see muted; subtitles required if audio carries info | | Content rule | **Only in-app footage** — no marketing intros, no logos, no real people | ### Google Play Promo Video | Spec | Value | |---|---| | Source | **YouTube URL** (link, not upload) | | Length | **30 seconds recommended**, 2 min max | | Format | Landscape preferred (Play autoplays) | | Audio | Allowed and recommended | | Content rule | Less restrictive — real people, narration, marketing intro all OK | | Placement | Above screenshots on product page | ## The 30-Second Video Structure Use this beat-by-beat template (works for both platforms with adjustments): | Time | Beat | iOS Rule | Play Rule | |---|---|---|---| | 0:00–0:02 | **Hook** — show the outcome, not the app | In-app footage only | Can use logo/intro, max 3s | | 0:02–0:08 | **Problem framing** — text overlay states the pain | Text on app footage | Can cut to lifestyle b-roll | | 0:08–0:20 | **Core feature demo** — the "how it works" walkthrough | Real screen recording, sped up 1.25–1.5× OK | Same | | 0:20–0:26 | **Social proof / breadth** — quick cuts of other features, ratings, results | Must be in-app screens | Can show review screenshots | | 0:26–0:30 | **Resolution + CTA frame** | Show outcome state, no "Download Now" CTA (Apple rejects) | "Get it free" CTA OK | **Poster frame choice (iOS):** must be visually striking, no text-heavy. The 0:00 frame is what 80% of users see. ## Script Output Format When user asks for a video script, deliver: ``` APP PREVIEW VIDEO — — Variant Length: 30s | Platform: iOS / Android | Locale: en-US POSTER FRAME: 00:00–00:02 HOOK Visual: Text overlay: "" Audio: 00:02–00:08 PROBLEM Visual: ... Text overlay: "..." [continue per beat] PRODUCTION NOTES: - Record on , - Demo account state: - Speed adjustments: - Captions burned in (required if voiceover): yes/no ``` ## 3-Variant Strategy (iOS) Apple lets you upload 3 App Previews. Don't make 3 of the same — diversify by hook: | Variant | Hook angle | When iOS shows it | |---|---|---| | **A — Outcome** | Result-led ("Sleep better in 7 days") | Default first preview | | **B — Demo** | Feature walkthrough — pure UX | Second | | **C — Social proof** | Numbers, results, testimonials in-app | Third | User can reorder. Default to Outcome first unless category demands demo (e.g. complex tools). ## Production Checklist Before submission: - [ ] Captured at native device resolution - [ ] No "Download Now", "Available on App Store", or app icon overlays (Apple guideline 2.3.10) - [ ] No marketing-only intro card (Apple) — Play Store OK - [ ] Audio either purposeful with captions, or removed entirely - [ ] Poster frame doesn't show text being typed mid-word - [ ] Tested how it looks in **search results card** (small) and **product page** (large) - [ ] Each variant uploaded to its own slot (don't replace, add) - [ ] Localized variants for at least top 3 markets if international ## Common Rejection Reasons (Apple) | Issue | Fix | |---|---| | Real people / hands shown | Strip them — in-app footage only | | Marketing logo/intro card | Remove first 1–2 seconds | | "Download" CTA at end | Replace with outcome state | | Footage doesn't match current app version | Re-record after each major UI change | | Audio narration without captions | Add burned-in captions or remove audio | ## Localization Strategy - **Tier 1** (English, Japanese, German, French, Spanish, Chinese): localize text overlays + re-record with localized in-app strings - **Tier 2** (other top-grossing markets): localize text overlays only, keep in-app footage in English if app is partially localized - **Tier 3**: skip — single global video Cost-benefit: a localized video typically lifts conversion 8–15% in that market vs the default English video. ## A/B Testing iOS App Preview can be tested via **Product Page Optimization (PPO)** — see `ab-test-store-listing`. Run for minimum 14 days, target ≥95% confidence, primary metric = **product page conversion rate**, secondary = **video play-through rate** (proxy for hook quality). ## Cross-Skill Handoffs - Static screenshot strategy for slots 1–10 → `screenshot-optimization` - Run a PPO test on the video → `ab-test-store-listing` - Localizing video text overlays per market → `localization` - Video isn't in the right slot order or alongside the right screenshots → `screenshot-optimization`
