Chimney liners go in as a stainless SKU still

The liner is the catalog photo you I2V on Seedance 2.5. This is the SKU going in, not a soot-to-clean sweep interpolation.

A chimney-liner listing is a stainless tube you already tooled: diameter, wall, the flex or rigid you actually ship, the cap that belongs to that kit. Motion is the part going in — a slow feed, a hold on the bead, a light rake across the steel. It is not two stills of a dirty flue becoming a clean flue. That interpolation is a different job on a different page. Photograph the liner. Animate the liner. Do not morph creosote.

The liner is the SKU, not the sweep

Distributors compare the still to the carton. Diameter versus diameter is a warehouse fact. Flex versus rigid is a claim on the spec sheet. Mixing those into one generate is how a kit becomes a cousin tube with invented corrugation.

Photograph the approved unit the way you would print a line card: square-on, bead true, logo lockup readable, no invented listing stamp. That file is the identity. Text-to-video of "stainless chimney liner dropping into a Victorian stack at golden hour" rebuilds the corrugation and parks a house under it. You sell this kit.

Chimney sweeps interpolate creosote to a clean flue is the nearby service page: two stills of the same stack, dirty then clean, first-last on that geometry. A sweep ad that books is disappearance of creosote. A liner OEM ad that books is the stainless going in. Do not rewrite the sweep as a catalog row. Do not first-last a sooty crown into a liner you never photographed. That is a morph of two businesses.

If you would not print the still on a spec sheet, do not buy motion. Crop the warehouse clutter that is not the SKU. Crop people. A tech in the still becomes a tech in the motion. You do not want a generated cousin of that tech talking "what you should do before winter."

Seedance 2.5 I2V on the catalog still

The still-to-motion job on this family is image-to-video. Open it from AI image-to-video. The published family page is Seedance 2.5: 4s–30s in one pass, 720p ceiling, 47 credits listed, native audio with the picture. I2V is the still-to-motion job on that family; the published URL is the family page.

Prompt camera and physics only. Slow feed of the liner already in the still. Light shift across the bead. A cap seating if the cap is already in the plate. Do not re-describe the kit in the paragraph. Re-describing is how the model draws a second liner. Do not ask the generate to add a sooty flue "for context." Context is a second still you shot of the same kit, or it is overlay you typeset later.

Thirty seconds in one pass holds a SKU. Stitching four short text-to-video clips is how the corrugation drifts. 720p is the ceiling on this endpoint. A 2K lookbook plate is a different delivery row. Identity is still the I2V choice.

Native audio will invent a soundtrack if you leave the mix unnamed. Write silence, a metal-on-clay scrape you actually want, or plan score after lock. A talking plant host is a different generate. The empty liner does not need a mouth. Quoted "book a sweep" in the prompt does not become a readable title. Overlay that after lock.

A last frame is optional control. Use one when you photographed two states of the same kit — coiled on the bench as first, seated in the photographed flue as last — and the travel has to land. Two photos of two different diameters is a morph of the SKU. If the bead is wrong in the jpeg, it is wrong for every second you generate.

HVAC and contractor pages are install calendars

/for/hvac-companies is seasonal plant: pre-summer AC, pre-winter furnace, a system explainer. Two posts a week. 9:16. That page is indoor mechanical, not a stainless kit on a bench. Do not rewrite the HVAC calendar onto a liner. Seasonal type can overlay a locked plate. A generated house is not a spec sheet.

/for/contractors is process transparency behind walls — demo, framing, a walkthrough. A chimney liner is not a renovation arc. Nearby home-services pages stay nearby. This page owns the catalog still going in.

A contractor who I2Vs the OEM jpeg and captions it as last week's install has used the wrong still the other way. The flue, the van, the crown are the proof. The carton photo is the SKU.

What this listing is not

It is not soot-to-clean interpolation. That is the sweep page, two stills of one stack.

It is not a talking tech walking "your air is unsafe." You do not need a mouth on a liner feed. It is not a text-to-video "stainless liner sliding into a historic chimney." That invents the corrugation. The corrugation is the SKU.

Pause on the bead. Is it the liner on the quote? Yes: ship. No: you used text-to-video, or you first-last'd a dirty flue into a cousin kit. Go back to the still.

FAQ

Can I interpolate a dirty flue into a liner install and skip the catalog photo?

No. Soot-to-clean is the sweep job: two stills of the same stack. Liner OEM is the stainless kit going in. Pin the catalog still. Animate that. A morph from creosote into a tube you never photographed is a different product.

Why Seedance 2.5 instead of a talking plant tour?

Because the product is still-to-motion of an approved liner, not a mouth. Seedance 2.5 is 4–30s, 720p, 47 credits, native audio. I2V is the still-to-motion job on that family; the published URL is /models/seedance-2-5. A presenter row will talk over a chimney it invented.

Is this the HVAC or contractor audience page?

No. HVAC is seasonal indoor plant. Contractors are behind-the-wall process. This job is a stainless SKU still, animated as it goes in. Do not copy those /for pages onto the kit.

Do we need a last frame of the liner seated?

Only when you have a second approved still of the same kit and the shot has to land on the seated bead. A single hero still with a slow feed is the usual listing. A last frame is control, not a default. Two different diameters is a morph.
