## What it does

The skill outlines how to build short 6–15 second ecommerce promo spots in Remotion. It defines a strict beat sequence: a hook, the discount reveal, a strike-through price drop, a hero product shot, a promo code with urgency, and a call to action.

Animation timing relies entirely on Remotion's `useCurrentFrame` and `spring` functions. Because it avoids CSS transitions and standard timers, frames remain synchronized during headless server rendering. Prices and percentage-off values derive programmatically from the source numbers to prevent display mismatches.

The composition is designed for batch workflows. Passing a folder of JSON files directly into `npx remotion render` produces distinct product videos from a single template.

# Sale Promo Video

Make a punchy 6–15s sale spot that announces ONE offer and makes a viewer act now: the discount lands, the price drops from was→now with a strike-through, the promo code and deadline read clean, the CTA closes. This is the offer announcement — not a feature ad, not a testimonial. Energy, accurate numbers, urgency.

## When to use

- Discount / percentage-off reveals ("40% OFF", "$20 off").
- was→now price drops with an animated strike-through.
- Black Friday / flash sale / clearance / launch-week / seasonal spots.
- Promo-code reveals with a deadline or countdown.
- One promo template rendered across many products/offers (price table → N videos).

For performance-ad variants use `ad-creative-video`; for customer quotes use `testimonial-video`. Stay on the offer.

## The arc

A sale spot is short and ordered. Each beat does one job; never stack two.

| Beat | Job | Budget (of 10s) |
|---|---|---|
| Hook | Brand + occasion ("BLACK FRIDAY") snaps in | 0–1.5s |
| Discount reveal | The big number lands ("40% OFF") | 1.5–4s |
| was→now | Old price strikes through, new price counts down | 4–7s |
| Product | One hero shot, the thing on offer | (under price, 4–8s) |
| Code + urgency | Promo code + deadline, held still | 7–9s |
| CTA | "SHOP NOW" + URL, clean hold | 9–10s |

Scale tighter for 6s (cut the product beat) or looser for 15s (let each beat breathe). Never lengthen the hook.

## Two non-negotiable rules

1. **The number is the message — keep it exact.** Prices and percentages must be computed, never typed twice. Derive `now` and the `% off` from `was` and the discount so they can't disagree. A promo video that shows the wrong price is worse than no video. Round currency to cents, format with `Intl.NumberFormat`, and use `tabular-nums` so digits don't jitter mid-count.
2. **One offer, one focus per frame.** A single discount, a single code, a single CTA. Competing offers kill the urgency. If there are two deals, make two videos.

## The signature move: was→now with a strike-through

Three things animate together and must stay in sync: the strike-through line draws across the old price, the new price counts down to its final value, and a micro-overshoot punctuates the landing. Drive all three from `useCurrentFrame()` — never a CSS transition or a JS timer — so a server render never desyncs.
