Fume hoods: sash still, overlay face velocity you measured
Photograph the hood. Overlay the velocity you actually measured. Do not let Veo typeset a number or a talking chemist.

A fume hood listing is a sash and a cert. The sash is a photograph of the unit you commission — glass height, baffles, the work surface, the room it sits in. The number is face velocity from the last test: the fpm or m/s on the sticker, the report, the commissioning sheet. Those two facts do not belong in one generate. A cinematic row that paints a number on the glass has invented a cert. A chemist talking “safe use” is a health persona YouTube already named.
Photograph the sash you actually certify
The honest plate is the hood where it hangs. Same corridor paint, same service fixtures, same sash stop the tech used when they measured. Facilities will recognise the tile. A paragraph will invent a nicer lab.
Do not send “photoreal chemical fume hood, 100 fpm, ready for use” to a stills model and call it the install. That sentence contains a number you did not measure and a room you do not own. If the only photo includes a person at the sash, crop them or shoot again. Hands in the well are a worker you did not hire.
Turn a photo into a video is the named one-still verb: attach the hood still, describe the motion, get a clip that opens on that file. The agent asks duration, aspect, and resolution, then picks an image-to-video row. Cost is priced per model, shown before you confirm. Prompt travel only — a locked camera, a light rake across the sash, no new baffle, no new room. Do not prompt the sash to drop to a height you did not photograph. Sash height is part of the cert. A guessed opening is a different face velocity.
The launcher for the same job is image-to-video: upload is frame one. Text-to-video of “a lab hood with air flowing” rebuilds the cabinet.
Overlay the number from the cert, not from Veo
Face velocity is a string you already wrote down. “92 fpm at 18 in sash.” “0.5 m/s, as tested 12 March.” Copy that string. Do not ask a video model to letter it into the glass.
Add a text overlay burns one authored line for the whole clip: add_video_captions, your caption_text, top, center, or bottom. Nothing is transcribed. A mute sash still has no speech to caption. One persistent cert badge is this tool. Sash height, then velocity, then “do not block the baffles” as three beats is timed overlays — a different job. Crop to the ship ratio before you overlay. Picture lock, then type.
Veo 3.1 is the talking cinematic row people reach for when they want the number “in the shot”: native audio, official 4K tier, 4 / 6 / 8 second clips, listed 40 credits. It is a scene generator. It is not a typesetter. Pause any Veo take that “shows 100 fpm” on the sash — the glyphs are the model’s, not the report’s. You cannot edit them. You cannot defend them. Do not brief Veo to invent a chemist either.
Flux 2 Max is an empty-hood plate, not a chemist
If you do not yet have a usable site photo and you need a catalog still of the box — sash geometry, empty work surface, labeled as a product render — Flux 2 Max is the photoreal stills row: 7 credits, text-to-image, ultra-detailed photorealistic outputs. Prompt the cabinet, the sash, the baffles. Do not prompt a person. Do not prompt a number.
Flux 2 Max will not become your corridor because you named the building. When the listing has to be the serial on the work order, photograph it. Use Max when you can live with a product render you will label as a render, never as the certified install. Do not ask Max to typeset face velocity. The cert is overlay after picture lock, or it is not on the file.
A talking chemist is a health persona
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 chemist walking sash height, “you should,” or a protocol at the glass is that shape. Labelling the face AI does not leave the bucket.
A silent hood on a real wall is not that shape. Authored type is typesetting, not a mouth. A real named hygienist on camera is a different file. Generation can still do the cabinet. It cannot be the consult. Photograph the certified sash. Hold that still. Burn the report string as overlay.
FAQ
Can Veo typeset the face velocity if I put the number in the prompt?
No. Veo 3.1 will invent glyphs you cannot edit and a cert you cannot defend. Write the measured string. Burn it with add a text overlay after picture lock.
Why not generate a chemist so the hood has a demo?
That demo is a health persona. Photograph the empty sash. Overlay the velocity from the report. A real named hygienist, on a different shoot, if you need a voice.
Is Flux 2 Max a substitute for the site photo?
Only as a product render you will label as a render. Flux 2 Max is 7 credits, text-to-image, photoreal. It cannot ingest the corridor. Use it for an empty SKU still with no chemist and no painted fpm. The certified install is a photograph.
Can I animate the sash opening so viewers see the well?
Not from one still unless you accept a guessed height. Sash height is part of the cert. If you need travel, shoot two approved stills of the same hood at two tested stops and interpolate those — a different job. This page is a sash still plus overlay.
