Swing gates interpolate the same posts, closed then open
Flux 3 first-last at 9cr interpolates the operator on the same posts; /for/garage-door-companies is a sectional door, a different product than this swing hardware.

Automatic-gate OEM content is a bounded motion problem. You already own both stills: leaves closed across the opening, leaves open on the same posts. The ad is the travel. Do not prompt a model to invent the driveway, the house, or a cousin operator from a paragraph.
Same posts, closed then open
Photograph the pair on the opening it ships for — same lens height, same posts, same hinge geometry, same light family. Closed leaves are the first frame. Open leaves on those same posts are the last frame. Composite the open state only if the geometry is still this opening. A different driveway is a morph.
First-last frame takes those two stills and generates the motion between them. Ordinary image-to-video knows where it begins and improvises the rest. First-last has to land. The arc of the shot is decided by you.
The two frames have to be plausibly connectable in the time available. Same posts, same camera, same lighting neighbourhood. A wide of the street morphing into a macro of a hinge is a warp, not a swing. Keep the posts.
A loop (the same still in both slots) is ambient motion on one plate. This offer needs two states. Closed-to-closed is not an operator product.
Do not use a last frame that is a different SKU. The model will connect them. The connection is the artefact everyone notices — a leaf count that changes mid-travel, an arm that swaps, a post that grows a lamp.
Flux 3 interpolates the operator
Create a first-and-last-frame transition video is the named agent job: two photos in, one transition out. The agent passes them as first and last frame and picks a first-last-capable model. Cost is priced per model, shown before you confirm. This is not the plain “turn one photo into a video” capability.
Flux 3 First Last Frame to Video is the catalog row for that interpolation: start frame and end frame, native audio, durations from 5 seconds through 20, listed 9 credits. The catalog description names up to 1080p. Audio is on — write the mix (arm travel, a quiet pad) or write silence. A silent brief still gets a soundtrack you did not choose.
Prompt the travel, not the objects. The stills already contain the leaves and the posts. Name the mechanism: hold, then the leaves swing on the same hinges; camera locked; no new house, no new operator arm. If the endpoints share geometry, the morph reads as a cycle. If they do not, you get a mushy crossfade you could have made in an editor without a video bill.
Start at 5s or 6s. A long dual-leaf does not automatically need 20 seconds. Inspect the midpoint. Ends are held by construction. The middle is where a generator cheats — extra hinges, an arm that swaps, a leaf that grows. If the middle is wrong, reroll the motion, not the stills, unless a still was the lie.
Native audio is on this row. Write “no speech” if you do not want a voiceover explaining access control the stills already show. A generated crew shouting “clear the drive” is a second product glued onto the interpolation. Cycle rating, if it must appear, is overlay after lock, on type you typed.
Garage-door companies is a sectional door
Garage door companies are the nearby installer page: a snapped spring at 7am, a car trapped, same-day open; and a slow curb-appeal upgrade on a house like the buyer's. Film ideas there are a torsion spring replacement done safely, a door from bare opening to finished, the same house before and after. That playbook is a sectional door on a garage opening. It is not this swing hardware.
A gate OEM who copies that page — generated emergency spring, a fake garage, a synthetic tech walking “never adjust this at home” — has left the posts for a trade they do not sell. A garage-door company that I2Vs an OEM swing jpeg as proof they hung a driveway gate has used the wrong still the other way. Do not rewrite /for. Do not import a torsion-spring explainer onto a swing arm.
Contractors want what is behind the wall. Swing OEM wants the posts, closed then open. Do not mix them in one generate. A generated “estate entrance at golden hour” that almost matches the catalog is a different SKU: wrong leaf, wrong colour, wrong operator. The two photos are inventory.
One photo is a different job
One hero of the closed gate plus “make it swing open” is ordinary image-to-video, and it will invent the open state. Useful for a light sweep. Useless as a demo of travel you never photographed.
Image-to-video from one closed still will guess the landing. Automatic-gate OEM is the open face on those posts. Pin the open face as the last frame or you are not selling the cycle.
Text-to-video of “automatic swing gate opening on a luxury driveway” rebuilds the street. You will get a house, not this hinge. If the week is the SKU, it is closed, then open, same posts. Interpolate. Do not Omni a garage-door emergency and call it the operator.
FAQ
Can I animate one photo of the closed gate and hope it opens?
You can. The ending is then the model's guess. Swing OEM is the open face on those posts. Pin the open still as the last frame or you are not selling the travel.
Why Flux 3 instead of a talking-head model?
Because the product is interpolation between two approved stills, not a mouth. Flux 3 first-last is 5–20 seconds, up to 1080p, native audio, listed 9 credits. A presenter row will talk over an opening it invented.
Is this the same as the garage-door-companies page?
No. That page is a sectional door: emergency springs and curb-appeal upgrades. This hardware is a swing operator on the same posts, closed then open. Different product. Do not rewrite /for.
Is this the same as uploading one image to image-to-video?
No. One image is open-ended motion. Two images is a bounded landing. The agent notes that this capability needs first frame and last frame. Missing the open gate is a different job.
