A fence install is a property-line still that has to hold
I2V from the survey photo. Text-to-video invents a neighbor's house.
I2V from the survey photo. Text-to-video invents a neighbor's house. A fence quote is not a cinematic lawn. It is a line someone already measured and has to defend when the neighbor walks over. If the clip shows a different house, a different grade, or a panel that does not exist on that lot, the video is a drawing of someone else's property.
The survey still is the contract. Motion is allowed. Invention is not.
The survey photo is the only honest plate
A fence company ships work on a specific lot. The buyer knows the driveway, the slope, the tree they refused to remove. Text-to-video will invent a suburban stock shot: a pretty lawn, a generic two-storey, a run of panels that look like "fence." That is a different address.
Image-to-video starts from the frame you upload. Frame one is the file. Labels, posts, and the house behind the line survive because they were already in the picture. The prompt is for camera and physics — a slow push along the run, a slight parallax on the boards, nothing that reinterprets the lot. Re-describing the house in the prompt is how the model starts drawing a second house.
Seedance 2.5 is the still-to-motion family: four to thirty seconds, native audio, 720p on the I2V row, optional last frame when the move has a destination. A fence walk needs the measured line, moving — not a mood. The longer argument is Seedance I2V is still the still-to-motion job. This page is only the property line.
Motion the camera, not the lot
Once the survey still is locked, the generate is allowed to do three things:
- Move the camera along the run. Lateral drift, a gentle push toward a corner post, a hold on the gate.
- Add weather that does not rewrite geometry. Wind in grass that is already in the frame. Not a new hedge.
- Land on a second approved still if you have one — layout photo as first frame, completed install as last — so the interpolate is between two facts, not between a fact and a guess.
It is not allowed to "improve" the neighbor's siding, add a second storey, straighten a slope the survey recorded, or grow a fence style the quote did not sell. Those are claims. A homeowner will notice them before they notice your logo.
If the still is a phone snap with the crew's truck in it, crop the truck or shoot again. Do not prompt the truck out and hope the model rebuilds the driveway. The cheap place to lock the lot is the photograph.
Why a neighbor appears in text-to-video
Text-to-video has no plate. You asked for "a cedar fence along a suburban backyard at golden hour," and the model has to decide whose backyard. It will pick from the average of every fence clip it has seen. Average is not your survey. Average is a house that does not exist on that street.
That is the same fork as image-to-video versus text-to-video, except the cost of being wrong is not a wasted take. It is a clip that shows the wrong property. Fence work is adjacency. The person on the other side of the line will watch the ad.
If you do not have a photo yet, get one. A layout stake in morning light is enough. Then animate that. A style catalog of panel types still starts from stills of your samples, not from a paragraph about suburbia. The nicer T2V lawn is the invented neighbor.
FAQ
Can I prompt "match this survey" in text-to-video instead of uploading it?
No. A sentence is not a plate. The model will still invent the house and the grade. Upload the survey photo to image-to-video and describe only the camera.
What if the only photo includes the neighbor's house for real?
Keep it if it is actually in the shot and you are not implying you built their side. Crop if the quote is only your run. Do not generate a cleaner version of their facade. That is a new picture of a private building.
Do I need a last frame for a completed install?
Only when you have a second approved still of the finished line and the shot is meant to travel from layout to done. A single hero still with a slow move is the usual job. A last frame is control, not a default.
Is 720p enough for a fence ad?
For feed, yes. Identity of the lot matters more than a 4K invention of a different lot. Chase resolution on the same locked still, not by switching to text-to-video.
