Cyclone geometry must lock before you add swirl

Inlet, cone, and vortex finder are the SKU. I2V swirl after the photo holds. A model that redraws the cut sold a different efficiency curve.

A cyclone separator is not weather. It is a cut: inlet area, cone angle, vortex-finder diameter and insertion, the barrel you actually ship. Dust motion is allowed. A generate that fattens the cone or shortens the finder is a different machine. Photograph the unit or the approved section. Animate that still. Do not prompt “industrial cyclone with dramatic swirl.”

Geometry is the SKU

Procurement is comparing a drawing to a drawing. Inlet scroll versus tangential, the cone-to-barrel ratio, where the finder sits — those lines are the product. A cinematic cousin with a prettier vortex is a different efficiency story. You do not get to sell that story in an ad.

Lock the still before you spend on motion still applies when identity is a cut. Iterate the photo or the section until engineering would sign it. Then buy seconds. Text-to-video has to invent the vessel and the particle field. It will invent a vessel.

Do not “clean up” a weld in the prompt. Do not ask the model to hide a flange the drawing shows. Do not add a second inlet because the brief said “high capacity.” Those are claims. Overlay a capacity string after lock if you must show a number. Do not generate the number in the steel.

If the only still is a catalog rendering with a phantom cutaway that is not the SKU, stop. Animate a rendering only when that rendering is the approved geometry. A marketing cutaway that lies about the finder is a lie at 1080p.

Photograph the cut, then add swirl

Image-to-video treats the upload as frame one. Composition stays. Prompt camera and physics only: a slow orbit around the barrel, particle traces inside the volume the photo already implies, a light rake on the cone. Re-describing the inlet in the prompt is how the model starts drawing a second inlet.

Turn a photo into a video is the named agent job: attach the still, describe the motion, confirm duration and aspect. It is priced per model, shown before you confirm. Name the row. Do not let a general “make it cinematic” brief pick a talking generate.

A last frame is optional and strict. First frame the photo of this unit, last frame an approved section of the same unit, only if the two stills share geometry. A last frame from a different diameter is interpolation across two SKUs. That morph is the artefact a process engineer will notice before they notice your logo.

Do not generate a talking metallurgist or a constructed plant manager “explaining capture efficiency.” The number is overlay. The vessel is the still.

Wan 2.7 Image to Video is the swirl row

Wan 2.7 Image to Video animates a still at 1080p, 2–15 seconds, 15 credits. Catalog audio is unset — do not claim native audio, and do not write a voiceover into the motion prompt expecting a stem. Score later. Overlay later. Keep lips out of frame.

Three modes sit on that row: first-frame to video, first-and-last-frame interpolation, and continuation. First-frame is the usual cyclone job — photo holds, swirl is the only invention. First-last is the cutaway that must land on a second approved still. Continuation is for a keeper you are extending, not a way to “see more cinema” on a drifted cone.

Iterate at 2s, 3s, or 4s until the inlet still matches the photo. Fifteen seconds of a rewritten finder is a long miss of the wrong curve. 1080p is the ceiling on this row. That is enough for a product loop. A 4K cousin vessel is not an upgrade.

Prompt particles and camera. Do not prompt a new cut. If the swirl looks cheap and the geometry holds, you can live with cheap swirl. If the swirl looks expensive and the cone has changed, you sold the wrong machine.

OEM cut versus a plant film versus HVAC

Manufacturers already own the nearby plant job: line footage, a capability film, recruitment on the floor. That page is scale and process. A cyclone OEM is a cut. Do not rewrite /for/manufacturers. Do not hide a generic dust collector inside a factory tour. The SKU is the vessel you ship, not the hall it sits in.

HVAC companies own seasonal prep, a real diagnostic, a technician on a roof. That is contractor work on a building. A cyclone separator OEM is not a tune-up reminder. Name the difference: geometry on a photo, then swirl. Not a furnace checklist.

Efficiency, pressure drop, a model code — overlay those strings on the keeper. Generated type on the barrel is a misspelled curve you cannot edit. The plate stays clean until engineering would post the still.

The test: pause on the inlet and the finder. If they are the SKU, add swirl. If they have been restaged, you bought weather. Recycle the photo. Do not T2V your way to a prettier cone.

FAQ

Can I text-to-video a cyclone if I describe the inlet in the prompt?

No. A sentence is not a cut. The model will invent a vessel and an efficiency story that is not on the drawing. Photograph the unit. Run image-to-video. Describe only camera and particles.

Does Wan 2.7 Image to Video add a soundtrack?

Catalog audio is unset. Do not expect a native bed. Score after lock. Overlay the model code. Do not cast a talking engineer on the cone.

When is first-and-last the right mode?

When you have two approved stills of the same geometry — photo to matching section, or closed housing to an approved cutaway — and the shot must land. A last frame from a different SKU is a morph across two curves.

Should the efficiency number live in the generate?

No. Overlay it. A model that paints a capture figure on the barrel is a string you cannot proof against the datasheet, and a generate that also rewrote the finder sold a different machine while it was lettering.
