Goldmann tonometers overlay mmHg you measured; never generate an eye
The Goldmann prism-head still is the SKU, empty of a face: overlay the mmHg you measured as authored type, Nano Banana 2 is 8cr discounted for rapid catalog stills, and a generated cornea or photoreal clinician is a YPP kill.
The Goldmann prism-head still is the SKU, empty of a face: overlay the mmHg you measured as authored type, Nano Banana 2 is 8cr discounted for rapid catalog stills, and a generated cornea or photoreal clinician is a YPP kill.
A Goldmann listing a buyer can match is this prism, this tonometer head, the slit-lamp mount you ship. It is not a cornea. It is not a constructed ophthalmologist walking intraocular pressure. Photograph the prism empty of a face. Stamp the millimetres of mercury you actually measured. Leave anatomy off the generate.
The prism-head still is the SKU
Procurement already knows the category. What they need is the serial they quoted: prism diameter, doubling prism, the mount a technician will seat on a slit lamp. “A modern eye exam, Goldmann applanation” invents a cousin head and an eye you did not consent.
Shoot the approved unit like a line card. Square-on or a three-quarter that still reads the prism face. Empty of people. If the only photo includes a face or a globe, crop them or shoot again. A generated patient is a hard stop. A generated cornea is anatomy you do not have a right to mint.
The AI product video generator is the hardware contract: reference photos are the ground truth. Zoom to 100% and read the prism marking before you keep a take. Fine text is the first thing a generator loses. Prompt only camera on the unit: a slow orbit of the head, a hold on the prism. Re-describing “ophthalmic exam in a clinic” is how the model draws a second chassis and a second body.
Identity of this prism is the listing. A nicer cousin on a nicer lamp is a different SKU. Get the photo. Inventing the device so the week has a clip is how a bid goes out against hardware you do not ship.
Overlay the mmHg you measured
Intraocular pressure is a measured number, or a published range. 16 mmHg. 12–22 mmHg, demonstration only. Video models do not typeset those digits. Image models will try; they will also invent a digit.
Add a text overlay burns one authored line for the whole clip — top, center, or bottom. It does not transcribe. A mute prism has nothing to listen to. Write the string as it sits on the reading you took, or on the cut sheet you already publish. If you needed the reading at 0s and a CTA at 4s, that is timed overlays, a different editor job.
Do not prompt “Goldmann tonometer showing 16 mmHg on the drum.” Do not run auto-captions hoping a transcriber invents a pressure nobody said. A generated drum that reads 16 when the sheet says 14 is a listing miss and a clinical miss.
Crop to the ratio you will ship before you overlay. Picture lock, then type. Readings change. The prism should not. Overlay the new number. Do not regenerate the head to change the drum. If the still already carries a sharp, real drum you photographed on the unit you ship, keep it. Do not “enhance” the scale. Prettier ticks are a different reading.
Nano Banana 2 is 8cr discounted for rapid catalog stills
Nano Banana 2 is Google’s ultra-fast lightweight image row: text-to-image, image-to-image, and edit-image, 8 credits, discounted (4 at 50%). Qualities 1K / 2K / 4K. audio is null. There is no duration. requires_image is false on text-to-image; image-to-image and edit-image keep a plate you already have.
Use it for rapid catalog stills of the head: crop a glare, drop a background, hold the prism. Lightweight iteration. A new text-to-image of “Goldmann exam” is a new clinic and a new eye.
Do not prompt a photoreal cornea, even “anonymised”; a slit-lamp beam on a globe; hands holding a lid; a “glaucoma specialist” walking the reading; a child, a dilated pupil, a fundus. Those are people, or medical images you do not have a right to mint. If you need motion on the real head — a slow turntable, no new room — photograph the unit and animate that file from the product-video door. Motion is allowed. An eye is not.
Prompted type inside Nano Banana 2 is a misspelled mmHg you cannot edit without regenerating the head. Keep lettering in the overlay. Proof any catalog still at 100% before you buy seconds.
A generated cornea or photoreal clinician is a YPP kill
Synthetic presenters on health and finance are a YPP kill. YouTube’s inauthentic-content third bucket is AI personas that present as human experts on health. A constructed ophthalmologist walking “what you should expect from this reading” is that shape. Labelling the face AI does not leave the bucket.
A silent prism on a real bench is not that shape. Authored type on the plate is typesetting, not a mouth. A real, named, credentialed clinician on camera is a different day and a different file. Generation can still do the head. It cannot be the consult, and it cannot be the eye.
A cornea in frame is anatomy. Do not prompt applanation on a globe, even “for demonstration.” A positioning demo is a patient and a protocol. Photograph the parked prism. Overlay the mmHg you measured and the IFU URL you already host. A real named applications person, on a different shoot, if you need a voice. Do not invent a globe so the unit has a scene.
Third-person description of the plate is allowed: the prism, the mount, the overlay. Prescription from a synthetic face is not. If the first three seconds look like an exam, rewrite until they look like a head. Never generate an eye.
FAQ
Can we generate a cornea so buyers see applanation?
No. That demo is anatomy and a protocol. Photograph the empty prism-head. Overlay the mmHg you measured and the IFU URL you already host. A real named applications person, on a different shoot, if you need a voice.
Why Nano Banana 2 instead of a talking cinematic row?
Because the listing is a catalog still, not a mouth. Nano Banana 2 is 8 credits, discounted, text-to-image / image-to-image / edit-image, 1K / 2K / 4K. A presenter row will talk over an exam it invented.
One overlay or timed lines for the reading?
One persistent mmHg badge is a single overlay on the whole file. Reading, then model string, then “for demonstration only” is timed overlays. Neither job transcribes. Neither job belongs in the Nano Banana prompt.
Is a disclosed AI ophthalmologist acceptable on the product channel?
Disclosure does not move a constructed health expert out of YouTube’s third bucket. Keep the prism plate. Keep the overlay. If someone must speak a protocol, that someone is a real named clinician, not a generate.
