Hot tubs: the unit still on the deck they have

I2V the lot photo. The unit on the deck they already have is the product. A generated cedar spa on a cliff is a different SKU in a place they do not sell from. Buyers are shopping a shell, a cover, a step, and whether it fits the pad they own.

Photograph the tub you will deliver — lot, a customer's deck you have the right to show, or the showroom. Then move that still. Do not prompt "luxury hot tub at sunset" and hope the jets match the price card.

The lot photo is the set

Trees, fence, pad, the HVAC in the corner — that is the install. Stripping it for a mountain is how a booked visit dies in the side yard.

Image-to-video keeps your upload as frame one. Prompt steam, orbit, water in the shell — not the cabinet colour. Re-describing is how you get a second cabinet.

Seedance 2.5 is the identity-lock family: one still (or first and last), 4–30 seconds in one take, up to 720p, native audio. One pass is why you do not stitch four clips and watch cover hardware drift. 720p is the ceiling on this row. A 4K showroom grade is a different model. The tub remaining the tub is this one.

SKU lock, not a mountain spa

A beautiful shot of almost-your-tub is a failed ad. Wrong jet grid, wrong cover, shell half a shade off — the buyer has been staring at that grid on the manufacturer page.

Product video is the same lock on a pack: two or three clean angles of the real object, then a scene around it. Use it when you want night or a seasonal re-skin without changing the shell. Zoom to 100% on the badge, panel, latches. Fine hardware dies first.

Do not send generated "tubs" as references. References are photographs. A single lot still is the default. Several true angles is the upgrade when the object must match across 9:16, 1:1, and wide.

First frame, then a move

Order of operations:

1. Lock the still. If the still is the wrong model year, stop.
2. Describe only the move. Steam, orbit, dusk on the same deck.
3. Inspect the SKU before you keep the take. Re-run rather than retouch a drifted panel.
4. Caption after. Type on a true plate. Do not ask the model to typeset "in stock this week" into the water.

A last frame is control: three-quarter to panel of the same unit. Two floor models are two SKUs.

Hands, sit, water feel — real footage wins. Generated water is a tell. I2V the establishing orbit; cut in the phone clip of the actual jets.

When the unit is the product

You are selling this shell on this pad. Lifestyle means weather and time of day, unit locked. A model the lot does not have is a still you do not have — do not generate one to pretend you do. Identity is the I2V choice. Resolution is delivery. A drifted tub at 4K is still the wrong tub.

FAQ

Can I generate a backyard the customer does not have, with my real tub in it?

Reference-to-video can hold a photographed unit in a scene you did not shoot. That is a placement, not a substitute for the lot photo when the ad is "what we have on the ground." Do not invent a yard that implies an install you cannot do.

Why not text-to-video a steam shot and overlay the logo?

Because text-to-video re-decides the shell. Logos on a cousin of your tub train the buyer on the wrong grid. Lock the unit in a still, then animate.

Do I need a last frame for a simple steam loop?

No. A single lot still with a short camera move or steam is the usual job. Add a last frame only when the shot must land on a second approved still of the same unit.

Is 720p enough for a dealer site?

For feed and most product-page loops, yes. For a large showroom display, pick a higher-resolution generate and still start from a locked still if the model accepts one. Do not trade the SKU for pixels.
