Kizik Sierra «Step In, Hands Free» — the full prompt pack
The exact prompts behind this ad: the full master prompt, all 6 frame beats, and the product lock we used so the boots never change — same pair, same gore panels, every frame.
Comment this word under the video and the pack that lands in your DMs is this one — Pack №8, the Kizik Sierra pack.

The result
This is the finished ad the pack below produced — a 16.7-second hands-free step-in, animated between the approved frames, from a phone photo to a sunny Utah street walk.

The master prompt
Copy it as-is. This is the complete prompt — product, location and timing already locked in. The frame-by-frame timing is built into the text.
Create a 14-second vertical 9:16 ultra-photorealistic women's footwear commercial on a sunny autumn street in Utah. One pair of Kizik Sierra Chelsea boots in Brunette (identity lock above) is the only footwear in the video. A young woman wears light-wash cuffed jeans and white socks. Her hands are busy the whole video — right hand holds a coffee cup, left hand holds a shopper tote — and NEVER touch the boots: she puts the boots on by simply stepping into them, hands-free. Her nails: glossy purple manicure with a small white IK logo on the index fingernail. 0.0–2.5s PHONE: close-up of her hand (purple manicure, white IK on the index nail) holding a smartphone; on the screen — the real product photo of the Sierra Brunette pair from the reference; her thumb taps the photo; sunny blurred street behind the phone. 2.5–5.0s THROUGH THE SCREEN → REVEAL: the camera pushes into the phone screen and out the other side onto the street: the same pair now stands at real size on the pale sunlit pavement, exactly as in the reference photos; warm daylight, soft shadows, a few amber leaves; the phone is gone. The boots never deform — a clean camera transition, no morphing. 5.0–8.0s THE STEP-IN (central action): low camera at pavement level. Her legs enter frame — cuffed light jeans, white socks. Both her hands stay UP and busy: coffee cup in the right, tote in the left; she does NOT bend down. Her right foot slides straight down into the right boot: the heel gate flexes, the elastic gore stretches and settles, the heel clicks into place. Then the left foot steps into the left boot the same way. No hands ever touch the boots. 8.0–10.0s GATE MACRO: extreme side close-up of the boot already on her foot — fingertips with purple manicure (white IK on the index nail) brush once across the nubuck and the elastic gore panel, showing the matte texture and the panel's give; the debossed 'kizik' wordmark on the heel counter is visible; coffee cup still in her other hand at frame edge. 10.0–12.5s WALK: low tracking shot alongside the boots; she walks toward and past the camera along the sunny street, coffee in hand; the chunky two-tone lugged sole reads clearly in motion; light facades blur behind. 12.5–14.0s HERO: the pair stands in a three-quarter hero composition on the pale pavement, warm daylight, soft city bokeh behind, light settling. Hold. (Final anchor frame = clean pair hero; the animated end-plate with the product name is added in post-production.)
All 6 frame beats
The beats the master prompt breaks into — each beat starts or ends on an approved anchor frame:

A note on the prompt as actually used
The master prompt above is reproduced verbatim from the production file — including the GATE MACRO beat, where fingertips brush the nubuck and the gore panel. That is the prompt as written. The published final deliberately does NOT use that touch: under the owner's hands-free story rule, the touch was cut out of the final entirely. In the final, beat F4 is a clean macro of the worn boot with no hand in frame, followed by the first steps — the Flow segment's clean window (1.50–4.50 seconds of the clip) is what made the cut; its opening 0–1.25 seconds, where a finger presses the top edge of the gore panel, was excluded, as was the tail of the step-in segment from about 4.0 seconds where a hand descends toward the boot. No hand ever touches the boots anywhere in the final, and there is no finger-swipe sound: both step-ins happen by foot alone. The touch in the prompt line is the original plan, not the delivered film — and that difference is the whole point of this pack's USP.
Timing: the prompt line is 14 seconds plus an approximately 2-second end-plate; the published final is 16.70 seconds, built as Grok S1/S2 at 2.5 seconds each, Flow trims at 3.0 / 3.0 / 3.5 seconds, and a 2.2-second hold on the F6 anchor. The animated end-plate (“Sierra Chelsea Boots” / “Kizik • kizik.com”) runs from 14.7 seconds, and the demo watermark ends before it.
Two more honest facts about the published final. First, the Flow walk segment's tail (from about 4.5 seconds of the clip) materialised a second, unworn pair on the pavement — that tail is not in the final; the hero is a hold of the true F6 anchor, so there is only ever one pair on screen. Second, the store's own product page listed the Brunette colour as sold out in all sizes on 16.10.2026 — this pack documents the ad as it was made, not current availability. No prices are in this pack: the store price of the Sierra is internal only and does not appear here or in the tutorial texts.
The product lock
The identity block pasted into every generation, word for word. The passport sheet itself is built only from the store's own official photos — that is why the boots never drift.
Identity — pasted into every frame
The product is EXACTLY the women's Chelsea boot from the reference photos: Kizik Sierra Chelsea in Brunette — ankle-high boot in rich medium-dark brown WATERPROOF NUBUCK, matte finish, slightly lighter worn highlights on the vamp and rounded toe. Dark-brown elastic side gore panels on BOTH sides, set in a U-shaped tonal stitch line. Centre back seam with double stitching, small fabric pull tab at the top back, debossed lowercase 'kizik' wordmark low on the outer heel counter. Chunky two-tone sole: darker scuff strip on top, lighter taupe EVA midsole with wavy contour lines on the side, gum-tan rubber lugged outsole with deep rectangular lugs. NO laces, NO zippers, NO buckles. Hyperrealistic. The boots must NOT change shape, colour, panels or proportions between frames — the same physical pair in every frame.

How to run it — the short version
Three steps. The prompt alone is not enough: the frames and the passport do half the work, and their exact build is the part we keep in the paid work.
Choose the still frames the video will move between — the 6 beats above are your map.
One identity sheet for your product, locked word-for-word into every generation — like the Kizik lock above.
Start frame + end frame pinned, short segments, one approved frame feeding the next — the product stays identical to the last frame.
