Electrical OEM: the breaker still, overlay amperage
Do not let a model invent ratings.
Do not let a model invent ratings. A breaker ad is a photograph of this handle, this housing, this pole count — then a slow hold — then the ampere string you typed. It is not a talking panel. It is not a video model guessing 20A on a 15A SKU.
Amperage, AIC, trip curve, UL marks: those are claims a specifier will inspect. A 2 that becomes a 3 for six frames is a scrap part on a feed.
Photograph the breaker you will ship
The listing photo is the contract. Square-on. Cover or blank factory type if you will overlay. That file is frame one. Image-to-video keeps the upload as the opening frame so the handle colour and the screw pattern survive.
The image-to-video row on Seedance 2.5 is the hold: required still, first frame plus optional last frame, native audio, 4s–30s, 480p / 720p, listed 47 credits, billed resolution-based per second. Catalog copy: one frame into continuous motion without stitching shorter clips. Handle off to handle on is a last-frame job only when both stills are the same unit at the same angle.
720p is the ceiling. Enough for a faceplate. Text-to-video of "an industrial breaker in a clean electrical room" will invent a cousin SKU and a rating the catalog does not sell.
Prompt only the motion. Do not re-describe "commercial 42-circuit panel, 200A main." That paragraph restages the hardware. A generated electrician is a likeness you do not have. Empty gear, or a hand you photographed on the handle.
Amp is overlay, never a prompt
After picture lock, print the number yourself.
Add a text overlay to a video burns one authored line for the whole clip — "20A / 10 kAIC" — at top, center, or bottom. It does not transcribe. Silence in the file does not change the string. Position is a three-way enum, not a free pixel.
If the spec has to change — amp, then AIC, then pole count — that is timed overlays, not one persistent headline, and not auto-captions. Auto-captions listen. Nothing said "20A" unless a person said it.
Do not put 20A on the breaker in the prompt. On-screen text in generated video is the failure: Versely renders at 25 fps, so an eight-second clip is 200 frames, and a wrong glyph is the frame the eye locks onto. A text overlay burns one authored line; it does not listen. Crop to the delivery aspect before you overlay.
Motion is allowed; ratings are not
Native audio on Seedance can be plant noise if you write it into the prompt. It is not a panel that recites its own AIC.
Order: real still of the SKU; approve it as this breaker; animate on the I2V row if the brief needs a hold; burn the amp string as overlay. Swap the string for the next SKU without regenerating the housing. Reverse that order and you will regenerate a panel to fix a typo.
FAQ
Why not let the model write "20A" on the handle?
Because 20 is a claim. Overlay text is editable without regenerating the housing. In-frame type is a new generate every time the SKU changes.
Is Seedance required, or will any I2V do?
Any image-to-video row can move a locked still. Seedance's I2V row lists first/last frame and a 4s–30s single pass at up to 720p. Use it when the faceplate has to hold.
If an engineer says the rating on camera, do I still overlay it?
No. That is the caption job: speech in, styled subtitles out. Overlay is for a line nobody said.
Can I overlay a full panel schedule?
One overlay is one string for the whole clip. A schedule is a still composited, then a few timed callouts. Do not ask one burn to be a one-line diagram.
