vid-sizzle-reel

Generates a high-energy sizzle reel or hype video from brand assets and key messages. Pipeline: HyperFrames HTML composition (GSAP timelines) → headless Chromium → FFmpeg H.264 MP4. No Runway. No Pika. No AI video APIs. Zero runtime cost beyond Node.js + FFmpeg.

Differentiation from vid-product-launch:

vid-product-launch tells a narrative story — one earned reveal, five sections, tension arc
vid-sizzle-reel creates energy and excitement — fast cuts, music-first, no single story beat

Critical Rules (read before every generation)

Write the key messages yourself — or ask the user to write them. These are the exact phrases that appear on screen. "AI will figure it out" produces filler. 3-5 sharp lines is the entire content of a sizzle reel.
Brand name appears ONLY in the Land section. Cold Open and Build create tension without naming the brand. The Land section is the payoff.
Declare the rhythm pattern in a comment at the top of the script before writing any HTML. Format: // RHYTHM: flash-sequence | Cold[0-5s]: stat | Build[5-40s]: msg(1.5s)|flash|... | Peak[40-55s]: ... | Land[55-60s]: logo+CTA. Every timing decision checks against this.
