Boiler psi belongs in captions, not in a voiceover

MAWP and fuel type are authored caption lines on the tank still. A VO engineer is a different file. Do not let a video model invent the ASME stamp.

A boiler listing is a specific vessel. The buyer knows the series, the fuel, the pressure on the nameplate. A cinematic generate that "has the stamp in the shot" will redraw the ASME mark, invent a psi, or swap gas for oil. That is a fabricated rating. Photograph the tank. Type the lines you can defend. Do not hire a generated mouth to read them.

The tank still is the SKU

The cabinet, the burner door, the nameplate already in the photo — those are inventory. Text-to-video invents a generic boiler: a pretty mechanical room, a plausible jacket, a badge that is "ASME-shaped." That is a different SKU. The specifying engineer who pauses on the stamp notices before they notice your logo.

Image-to-video starts from the file you upload. Frame one is the catalog or lab still. Prompt camera and physics — a slow orbit, a hold on the plate, a burner glow you actually photographed — not a second vessel. Re-describing the unit in the paragraph is how the model draws a second unit.

Keep the nameplate large in frame. If the stamp is unreadable in the jpeg, reshoot. Do not ask motion to sharpen characters that were never there. A last frame is allowed when you have a second approved still of the same model — boxed SKU as first, installed unit as last — only when both photographs are that model. Two photos of two different jackets is a morph of the SKU.

Proof at 100%. The stamp, the fuel badge, the model number are the pack-text of this category. If the generate melted them, throw the take out.

MAWP and fuel are lines you wrote

Maximum allowable working pressure, fuel type, a model string — those have to match the nameplate and the cut sheet. A video model painting them onto the jacket will miss a character. Overlay is the typesetter.

Add a text overlay to a video burns one authored line, whole clip, top / center / bottom. The agent twin is add a text overlay to my video: add_video_captions, the exact caption_text, a position. It does not transcribe. Silence, native rumble, a music bed — none of that changes the string. "MAWP on the nameplate · gas" is a caption you typed. It is not a voiceover.

Several specs on a beat — pressure, then fuel, then a CTA — are timed overlays on the same locked take. Font, size, colour, and position apply to the set. Do not regenerate the tank to "include the psi this time."

Add captions to a video is the speech path. It listens. A silent tank plate has nothing to transcribe. Running auto-captions on a rumble hoping the MAWP appears will not typeset your cut sheet. Use captions when a real named person spoke, and you want their words burned. Use overlay when you wrote the spec.

A VO engineer is a different file

A constructed engineer walking MAWP, fuel, and "what you should spec" is a talking-head generate glued onto a product still. That is a second contract. The tank does not need a mouth. The stamp does not need a narrator.

If a real applications engineer is on payroll and on camera, film them. Transcribe them with captions. Do not generate a cousin in a hard hat reading a rating the model invented. Do not prompt a native-audio cinematic row to "explain the boiler" and hope the psi matches the plate.

Score after lock if the still needs room tone. Overlay the spec after crop. Offers and fuels change. Copy lock can be later than picture lock. If either is open, do not burn.

The AI product video generator is for a locked object in a new pad, not for a talking spec. Check the badge at 100%. I2V from the tank still. Overlay the lines. No third method that typesets ASME in the prompt.

HVAC /for is the install; this is the nameplate

HVAC companies are the local installer. Seasonal urgency, a real pad, a technician intro. That page is not an OEM catalog. Mixing the briefs is how a manufacturer ships a fake mechanical room of a cousin boiler, and how a local shop ships a catalog jpeg as last Tuesday's install.

Manufacturers are a wider neighbour: the floor, sparks, a capability film for procurement. A boiler OEM can film the line. The listing clip is still the vessel, not a plant tour with invented stamps.

Plumbers are further out. Their still is the call they take. An OEM who copies a plumber playbook — generated leak, fake basement — has left the nameplate. Seasonal copy can overlay a locked tank. It cannot invent the house.

Three jobs:

• The SKU. Photograph the tank. Overlay MAWP and fuel.
• The install. Film the pad. That is /for/hvac-companies.
• The plant. Film the floor. That is /for/manufacturers.

Psi belongs in type you wrote. It does not belong in a voiceover a model performed.

FAQ

If the nameplate is already readable, do I still overlay MAWP?

No. Readable stamp is the typesetter. Overlay when the photo cannot hold the string, or when you need a feed-sized callout the 6-point plate will not survive. Do not overlay a different psi than the plate.

Should I generate a VO, then caption it, so the psi is "in captions"?

No. That is a talking file plus a transcript of a rating the mouth may have invented. Author the line. Burn overlay. Captions are for speech that already happened on a real take.

Can an OEM run the HVAC contractor playbook?

Not as a substitute for the tank still. HVAC companies is a local-install calendar. An OEM listing is the vessel. Seasonal type can overlay a locked unit plate. A generated basement is not a spec sheet.

Why not let Veo hold the ASME stamp in frame?

Because the model will paint a stamp, not typeset yours. If the generate melted the mark, throw the take out. Overlay the approved string on a locked still. Do not ship a cousin vessel with a plausible badge.
