Colposcope heads are Imagen 4 empty-optic plates at 4K, 4cr
Imagen 4 is 4K, 4cr, text-only; the optic is empty hardware, never a generated cervix — overlay working distance, no photoreal clinician.
Imagen 4 is 4K, 4cr, text-only; the optic is empty hardware, never a generated cervix — overlay working distance, no photoreal clinician.
A colposcope listing a buyer can match is this head: binoculars, illumination, the stand a biomedical engineer will recognise. It is not a generated cervix in the field, and it is not a photoreal clinician walking a protocol. Photograph the empty optic. Burn the working-distance string you already publish. Leave tissue and the mouth off the generate.
Empty optic is the plate
A colposcope is a SKU with a serial, a working distance, and an optic a clinic will match to a quote. Text-to-video of “a modern colposcopy suite, examination in progress” will invent a prettier cousin: a different head, a cleaner paint job, anatomy you did not consent. That is a different machine and a patient you did not hire.
Photograph the unit you sell. Head parked. Field empty. No phantom in the beam. No speculum in frame unless it is hardware you ship, sitting empty on a tray, with no anatomy. If the only photo includes a body, crop until only metal and glass remain, or shoot again. Do not prompt the anatomy out and hope the model rebuilds the optic.
The AI product video generator is the hardware contract: reference photos are the ground truth. Zoom to 100% and read the model badge before you keep a take. Prompt only camera on the unit: a slow orbit of the head, a hold on the empty objective. Re-describing “colposcope in a clinical exam room, ready for use” is how the model starts drawing a second head and a body. Keep private faces out of the plate. A photoreal “that clinician at the binoculars” is a likeness you did not clear.
Imagen 4 is 4K, 4 credits, text-only
Imagen 4 is Google’s text-to-image row: 4K, 4 credits, photoreal, text-only. Categories: text-to-image. audio is null. No duration. It cannot ingest the head photo. It will decide an optic. That optic is not yours.
Use Imagen 4 only when you need a closed, empty SKU still of the head you sell — binoculars parked, field empty, no body, no clinician — and you are willing to say the picture is a product render, not the suite. Quote geometry in the prompt if you must generate a catalog still. Proof at 100%. A wrong yoke is a different SKU. Do not send Imagen a paragraph that includes an exam. “Photoreal colposcope examining a patient” decides anatomy. Health content that invents a cervix is not a catalog still.
When frame one has to be the JPEG you approved, skip Imagen. Open image-to-video on that file. The upload is frame one. Motion is allowed only after the still is true: a slow orbit of the empty head, a tilt to the objective. Camera and physics. No new ports. No invented field on the glass. Native-audio I2V rows will mint a soundtrack if you do not write silence. Write “no speech, no invented clinician, room tone only,” or you will get a mouth you did not cast. Do not ask the model to narrate working distance.
Overlay working distance after lock
Working distance is a claim from the cut sheet you already ship. Video models do not typeset it. Glyphs in a generate have to be right every frame. They will not be. Prompted millimetres on the housing are a miss you regenerate to fix.
Add a text overlay burns one authored line for the whole clip — top, center, or bottom. It does not transcribe. A mute head has nothing to listen to. Write the string as it sits on the IFU: working distance, a SKU, “for demonstration only.” Proof the overlay against the nameplate. Overlay after picture lock. IFU revisions change. The optic should not.
Do not ask Imagen to letter working distance into the binocular housing. If the still shows a dark panel, leave it dark. A serial drawn by the model is fabricated panel type. Crop to the delivery ratio before you overlay. If the still already carries a sharp, real legend you photographed on the head you ship, keep it. Do not “enhance” the badge.
No photoreal clinician; never a generated cervix
Synthetic presenters on health and finance are a YPP kill. Help’s third inauthentic-content bucket is AI-generated personas that present as human experts on health. A constructed gynaecologist, “colposcopy nurse,” or clinician telling a viewer how to examine, when to biopsy, what a field “should” look like, is that shape. Labelling the face AI does not leave the bucket.
Do not glue a talking white coat onto the head inside one native-audio generate. If a protocol needs a voice, that voice is a real named credentialed person on a different day. Generation can still do the optic. It cannot be the clinician.
A generated cervix is anatomy. OEM catalog work does not need it. Do not prompt a field in the binoculars, even “anonymised”; a teaching-file still “for scale”; a speculum in use; a gown, a stirrup, a screening-age extra. Those are people, or medical images you do not have a right to mint. A child-sized exam is a hard stop.
A silent empty head on a real stand is not the YPP shape. Authored type on the plate is typesetting, not a mouth. Third-person description of the hardware is allowed: the optic, the stand, the working-distance overlay. Prescription from a synthetic face is not. If the first three seconds look like an exam, rewrite until they look like a head.
FAQ
Can we generate a cervix in the field so buyers see what the optic does?
No. That field is anatomy. Photograph the empty head. Overlay working distance and the IFU URL you already host. A real named applications person, on a different shoot, if you need a voice. Do not invent tissue so the optic has a scene.
Why not Imagen 4 the suite if we do not have a photo yet?
Imagen 4 is text-only. It cannot hold this stand. It will invent an optic that is not the serial on the work order, and it will be tempted to fill the field. Get the photo. Use Imagen 4 only for a closed, empty SKU still you will label as a product render, never as the clinic, never as an exam.
Is a disclosed AI clinician acceptable on the product channel?
No. Disclosure does not move a constructed health expert out of YouTube’s third bucket. Keep the empty optic. Keep the overlay. If someone must speak a protocol, that someone is a real named credentialed person, not a generate.
Can I I2V the empty head without overlay?
You can. Then working distance is missing unless it is already readable in the pixels. Motion on the real optic is allowed. Invented anatomy is not. If the distance string has to survive a pause, write it and burn it after picture lock.
