Switchgear cubicles I2V the door you photographed; no talking engineer

The lineup still is the contract. I2V a door swing only if the cubicle, bus, and interrupting rating stay the photo. No talking engineer, no invented mimic.

A switchgear listing is a photographed cubicle: door, handle, nameplate, the interrupting rating a buyer will match to a spec. Motion is allowed. A cousin lineup with a generated mimic panel is not. A constructed engineer explaining the rating is a different file you do not need.

The lineup still is the spec sheet

Factories argue over ratings. Text-to-video "medium-voltage switchgear in a clean hall, door swinging open" re-decides bus arrangement, handle, and the stamp on the nameplate every take. That is a pretty eight seconds and a failed submittal. Image-to-video does not get a vote on the interrupting rating. If the still is the wrong cubicle, you are buying seconds of the wrong cubicle.

Photograph square to the door. Even light. Nameplate readable. Crop the hall if the hall is not the SKU. Crop people. A millwright in the still becomes a millwright in the motion. You do not want a generated cousin of that millwright talking.

Electricians is the nearby contractor page: panel work, hazard finds, "don't DIY this." That is a field audience. It is not an OEM lineup. Manufacturers is the plant tour and recruitment film. A switchgear OEM can film a real line when engineering has cleared the shot list. The listing that procurement pauses on is still the cubicle photo.

Do not generate a mimic: invented meters, invented breaker faces, a SCADA wall the model sampled from a different vendor. The door you photographed is the door.

Wan 2.7 for the door you already have

Wan 2.7 Image to Video animates a required still: first-frame to video, first-and-last-frame interpolation, or video continuation. Two to fifteen seconds, 720p or 1080p, fifteen credits listed. The catalog does not list native audio on this row. Do not expect a generated door clank. Score after lock, or pass driving audio only if you already own that stem.

First-frame is the usual listing: cubicle still in, a slow push or a handle settle out. First-last is the door swing when you photographed two states of the same cubicle — door closed as first, door open as last — and the travel has to land on the bus you already shot. Two photos of two different bays is a morph of the SKU. Video continuation is for a take you already approved, not a way to invent a second lineup.

Prompt camera and physics. "Door swings on the photographed hinge, camera locked, no new meters." Stop. Do not re-describe the interrupting rating in the paragraph. The nameplate is already in the file. Re-describing is how the model redraws the stamp.

Keep the nameplate large in frame. Fine type is the first thing a generator loses. If the rating is the claim and it is postage-stamp size, overlay the string after lock instead of asking the motion model to typeset it.

Seedance 1 Pro Fast when the brief is a silent hold

Seedance 1 Pro Fast is accelerated image-to-video: image required, audio false, 5s or 10s, 720p or 1080p, sixty-two credits listed. Aspects include 16:9, 9:16, 1:1. The file is silent. That is the point when you do not want an invented hiss, an invented alarm, or a mouth.

Use it for a short silent hold on the locked cubicle — a 5s push you will overlay. Ten seconds of the same door is a long miss if the still was already wrong. Because audio is false, quoted lines in the prompt do not become a soundtrack. Plan type after lock.

When the object must stay yours and the hall has to change — a 9:16 crop of a cubicle you shot on the floor, a scene you do not have — that is not a talking engineer. That is the AI product video generator: reference-to-video from photographs of the real cubicle. Check the nameplate at 100% before you keep a take. Do not feed a finished lineup still to R2V and ask it to "just add motion." It will restage.

No talking engineer, no invented mimic

A constructed engineer prescribing an interrupting rating, a coordination study, or "what you should specify" is a synthetic expert. You do not need that mouth to sell a cubicle. The door is the product. If a human must speak, it is a real named person on a different day, on a file that is not pretending to be the lineup.

Do not glue a talking head onto the cubicle inside one generate. Do not prompt a mimic panel into the open door. If the interior was not in the still, it is not in the listing.

Pause on the nameplate. Is it the cubicle on the submittal? Yes: ship. No: you used text-to-video, or you first-last'd two SKUs. Go back to the still.

FAQ

Can I prompt the kA rating into text-to-video instead of uploading the lineup photo?

No. A sentence is not a nameplate. The model will invent a cubicle. Upload the door you photographed and describe only the camera. Overlay the rating if the stamp is too small to read.

Wan 2.7 or Seedance 1 Pro Fast?

Wan 2.7 when you need first-last on two approved stills, a 2–15s window, or 1080p I2V at the 15-credit listing. Seedance 1 Pro Fast when the brief is a silent 5s or 10s hold and you do not want a generated soundtrack. Audio is false on the Fast row. Neither row is a talking engineer.

Do I need a last frame of the open cubicle?

Only when you photographed the open state of the same cubicle and the shot has to land on that bus. A single closed-door hero with a slow push is the usual listing. An invented interior is a mimic.

Why not generate an engineer to explain the lineup?

Because the product is the cubicle, not a mouth. A constructed expert is a different legal file. Hold the door. Caption a real named person if you need a voice.
