Price Drop Alert
Price Drop Alert is a square e-commerce lifecycle card that fires off a price-change webhook matched against browse history — the "the thing you were watching just got cheaper" moment, rendered one card per watcher straight off the product feed. 27 seconds, 1:1 (1080×1080), 30fps, four scenes on a bone → ink → bone → forest ground rhythm: the personalised alert, the product on the one dark frame in the piece (price deliberately withheld), the payoff — old price struck in signal red beside the new price at 176px on a single shared baseline, with the saving in a forest band bled to the bottom edge — and a receipt row plus CTA pill. Eleven dynamic fields swap per render: customer_first_name, brand_name, product_image, product_name, product_detail, product_price_was, product_price, message_line, status_note, cta_label and cta_url; the minimum viable set is five (product_image, product_name, product_price, cta_label, cta_url), everything else has a documented fallback. Type is Instrument Serif / Geist / JetBrains Mono, and it is a direct sibling of the Abandoned Cart Nudge template, sharing its palette, 84px measure and ten-field product-feed contract.

Used Car Listing (Vertical)
A bright, friendly 24-second vertical (9:16) listing video for one car on an independent used-car lot, for Reels, TikTok and Stories, cut to the beat of its own upbeat 120 BPM track. The vertical sibling of Used Car Listing, with the same 27 fields, so one dealer payload renders both formats. Each landscape lot photo sits whole in a full-width framed card, never cropped to the hood, with the text below it and clear of the platform buttons. Five scenes: the car with a badge sticker, a big price tag with the mileage, three highlights as a checklist, three key numbers, and a dealer card with a large phone number and a call-to-action button. Swap 27 fields per car: five photos, year, make, model, mileage, price, price note, badge, three features, three numbers with labels, dealer name, city, phone, website and call to action.
Used Car Listing
A bright, friendly 24-second 16:9 listing video for one car on an independent used-car lot, cut to the beat of its own upbeat 120 BPM track. Made for small family-owned dealers who post each car on their website, YouTube and Facebook. Five scenes on a warm paper background with a navy and price-tag-yellow palette: the car with a badge sticker, a big swinging price tag with the mileage, three highlights as a checklist, three key numbers, and a dealer card with a large phone number and a call-to-action button. Ordinary lot photos (asphalt, sky, other cars) sit in framed photo cards with a light color grade, so they look clean without a studio. Every claim is a variable and no slot is optional. Swap 27 fields per car: five photos, year, make, model, mileage, price, price note, badge, three features, three numbers with labels, dealer name, city, phone, website and call to action. The vertical sibling uses the same fields.
Luxury Car Listing (Vertical)
A 29-second vertical (9:16) luxury car listing film for Reels, TikTok, Shorts and Stories, cut to the beat of its own 126 BPM track. The vertical sibling of Luxury Car Listing, with the same 24 fields, so one dealer payload renders both formats. Six scenes in a black studio with one tail-light red accent: a light-slit teaser, the car revealed on the music drop with a flash and a camera snap, three full-screen detail shots with a feature line each, three stacked performance numbers over speed lines, the price with a finance line, and a dealer end card with a framed hero photo. Landscape dealer photos sit in wide windows, so the car is never cut at the sides, and all text stays clear of the platform buttons. Swap 24 fields per vehicle: five photos (hero, three details, rear), make, model, year, mileage, three features, three spec values and labels, price, price note, call to action, dealer name, phone and website.
