Cable-tray fill percent is overlay copy, not Veo inventing ladders
Photograph the rung or trough you sell. Overlay the fill percent you will stand behind. Veo that invents a ladder rung pitch is a different NEMA class.

A cable-tray listing is a spec: ladder or trough, rung spacing, siderail height, the fill percent the catalog will defend. The buyer is an engineer, not a tourist. A cinematic plant corridor with "tray" in the prompt will mint a cousin ladder — wrong pitch, wrong width, a NEMA class you do not ship. That clip is a different product with your logo on the slate.
Photograph the rung or trough you sell
The SKU is a still. Front of a ladder span, a trough section on a table, a cut of the siderail you actually extrude. Even light. Rung pitch countable. If you would not put the still in a cut sheet, do not buy motion.
AI product video holds the photographed object while camera and scene move. Prompt motion only: a slow travel along the span, a hold on the splice plate, a slight parallax on the rungs. Re-describing "a galvanized ladder tray at 40 percent fill" is how the model starts drawing a second class.
Do not seed the generate from a competitor's catalog scan. That is their rung. Do not prompt a plant you do not own and composite your part number later.
A last frame is useful when you have two approved stills — empty span to dressed span, or ladder face to the splice. A last frame that is a Veo still of "industrial cable tray" interpolates into the wrong NEMA class.
Fill percent is overlay copy
Fill percent is a number you will stand behind on a submittal. It does not belong in a generate. Models letter numbers badly. Models also invent a fill that looks "about forty" and is not forty.
Add a text overlay to a video burns one authored string onto a plate you already locked. Whole clip. Top, center, or bottom. Flavour: "40% fill, this span," a part number, a CTA. Write the string. Burn it after picture lock. Offers and catalog revisions change; the rung does not.
Add a text overlay to my video is the named agent verb: the video, the exact caption_text, a position. It does not transcribe. It does not listen to the plant. Silence, a music bed, native dialogue on some other row — none of that changes the string. Using it as auto-captions wastes a burn on a line you invented while the speech went untyped.
If you needed the words to change at 0s, 2s, and 4s, that is timed overlay, not a persistent headline. If you needed speech on screen, that is captions on a take where someone actually spoke. Fill percent is not speech. It is a number you typed.
Do not ask Veo — or any video row — to typeset the fill into the shot. Generated glyphs misspell. Generated percents are not the percent engineering signed. Picture first. Type second.
Veo inventing ladders is a different class
Veo 3.1 is native audio, official 4K tier, 4 / 6 / 8 second clips. That is the cinematic talking row. A cable-tray SKU does not want that mouth, and it does not want Veo's plant. "Industrial ladder tray, cinematic factory, 40 percent fill" on Veo is how you spend the expensive talking meter on a corridor that is not your extrusion.
Rung pitch is a class. Siderail height is a class. A model that invents a pretty ladder has invented a different NEMA listing. The engineer on the other end of the submittal will count the rungs. The clip will fail that count.
Text-to-video is allowed for weather, particles, a cutaway where "a plant corridor" is the whole brief and nobody will match it to a SKU. It is banned as an identity tool for the tray you sell. If you find yourself prompting the pitch, you do not have a Veo problem. You have a missing still.
Muted autoplay still needs the fill line on the file. Veo will not letter it honestly. Overlay will.
Electricians and manufacturers are nearby, not this extrusion
Electricians convert on the local panel: hazard finds, fixture upgrades, "don't DIY this." That page is the wall after it closes. It is not a ladder-tray SKU, and it is not a reason to generate a panel with a made-up amp stamp next to your tray.
Manufacturers own the factory floor: a line at rate, a QC inspection, a capability film for procurement. Cable-tray OEM content can sit next to that floor. It cannot become a plant tour that restages the extrusion. The tray still is the product. The plant is optional and expensive if it is not yours.
Do not rewrite those audience pages. This job is: photograph the rung or trough, hold it as product video, overlay the fill percent, refuse Veo that forges a different class.
Pause on the rungs. If the pitch changed, the siderail grew, or a fill appeared that you did not type, throw the file away. Do not "fix" it by prompting a prettier plant.
FAQ
Can Veo 3.1 put our fill percent in the shot if we write it in the prompt?
It can letter something that looks like a number. That number is not the submittal. Overlay the percent you will stand behind after picture lock. Veo inventing the ladder is already a different class; inventing the fill on top of it is two claims you cannot defend.
Is overlay the same as captions?
No. Overlay prints one authored string for the whole file. Captions transcribe speech. Fill percent is not speech. Use overlay. Use captions only if a real named person spoke and you want that speech on screen.
Why not generate the tray from a spec sheet in text-to-video?
Because T2V re-decides rung pitch, width, and finish every take. The spec sheet is cheaper to lock as a photograph of the section you ship. Product video is how you stop paying video credits to discover the class moved.
Does the manufacturers page mean we should always show the plant?
It means the floor you own is an asset. It does not mean generate a plant. The tray still is always legal to animate. A restaged factory is optional and a different job.
