A locksmith ad is a three-second door, not a brand film
The job is the latch. Hailuo Fast finds the motion; do not spend Veo on a door.
The job is the latch. Hailuo Fast finds the motion; do not spend Veo on a door.
A locksmith ad that ships is a still of this cylinder, this deadbolt, this van door, then a few seconds of the thing actually moving. The viewer does not need a cinematic street at magic hour. They need to see the lock turn. That is an image-to-video job on a cheap, short row — not a 4K native-audio generate.
Hailuo 2.3 Fast is that row: a single still in, a 6- or 10-second cinematic clip out. Catalog credits 28 on the listed rate; the discounted 6s tier is 14. Catalog audio is unset. Features: Fast, Image-to-video, Cinematic. The AI video generator will run it. The still is the contract. The motion prompt is "bolt throws, camera static." That is the whole ad.
The latch is not a Veo scene
Veo 3.1 is already in the catalog: native audio, official 4K tier, 4 / 6 / 8 second clips. It is a good model for a talking street, a physics-heavy insert, a plate you will park on a large display. A locksmith paid-social unit is none of those. The hook is three seconds of hardware. Native dialogue does not sell a rekey. 4K does not survive a feed encode. Eight seconds of invented sidewalk is a brand film you did not brief.
Routing Veo at a door is how a shop burns a premium row on a subject Hailuo Fast was built to animate. Fast requires the image. You already have the image: a photo of the lock, the door edge, the key in the cylinder. Approve that jpeg. Then buy 6s. 10s is for a gesture that lasts 10 seconds — a full open-and-close, not a way to "see more cinema."
There is no duration between 6 and 10 on Fast. There is no text-to-video sibling on that card. If you only have a sentence ("a trusted locksmith arrives"), you are in the wrong family. Lock a still first. Then animate.
What the still has to hold
Fast will not invent a clean cylinder from a muddy phone snap. It will animate whatever you gave it. Label text on the lock body stays wrong for six seconds if it was wrong in the still. A wide of the whole facade hides the latch. Crop to the hardware. Light it so the bolt reads. Then prompt motion only: throw, retract, handle dip, door clearing the jamb. A second competing action in six seconds is how Fast looks expensive.
Do not write a monologue into the motion prompt and expect a voice file. Fast does not list native audio. If you need a line — "rekey same day," a phone number, a city — that is a caption or overlay on the keeper, not a Veo take with invented speech. The picture job ended when the bolt moved.
Keep Veo for the week that is not a door
A locksmith week is mostly doors. That is the point of not living on Veo. Run Fast for the latch pack. Change the row when the slate actually changes: a talking owner, a 4K hero for the site header, a clip that needs always-on dialogue. Those are Veo-shaped. A deadbolt is not.
The test is rude and useful. List the last ten ads you posted. If eight of them were "watch the lock move," you have been overpaying for cinema. Fast is the motion pass. Veo is the scene pass. A door is motion.
FAQ
Can I prompt Veo to "just do a simple door"?
You can. You will still pay for Veo: native audio, 4K tier, 4 / 6 / 8 second cinematic clips. The model does not become Fast because the prompt said simple. Pick the row the job is.
Does Hailuo 2.3 Fast work from text only?
No. It requires an image. Generate or shoot the lock still, crop to the latch, then run Fast at 6s. Text-only locksmith copy belongs in an overlay after the keeper, not in this generate.
Should I run 10s so the ad feels like a film?
Only if the gesture lasts 10 seconds. 10s on Fast is the other duration on the card (56 full / 28 discounted), not a brand-film upgrade. A three-second throw does not get better at 10s. It gets padded.
Where do I add the phone number?
Not in the video model. Fast has no native-audio promise, and burned-in type in the generate is a misspelled string you cannot edit. Animate the latch. Caption or overlay the number on the file you are keeping.
