What Object Swap Changes
Object swap edits one element of a shot and leaves the rest of the frame intact. Replace a product on a shelf, a cup on a table, a jacket on a performer or the entire background — without reshooting anything. Because the source clip is real footage, the result inherits the lighting, the shadows, the camera movement and the way the subject's hands move around the object. The person stays the same person; the timing stays the same timing; only the thing you named changes.
How to Use Object Swap in 3 Steps
Step 1: Upload your clip and pick the seconds
Drop in a normal camera video, then select any 3–10 seconds. Tracking shots and handheld clips both work.
Step 2: Point at your references and describe the change
Choose what you are changing — a product or object, an outfit or the background. Optionally add up to four reference images of what should appear and call them @Image1, @Image2 and so on in the prompt. Say what should change and what must stay.
Step 3: Generate and download
The Generate button shows exactly what the job will cost. Most swaps finish within a few minutes; if one does not, you get the credits back.
Pointing at References: @Image1 and @Image2
Object swap reads references in the order you upload them, and you call them by name in the prompt. Write "@Image1" for the first image you attached and "@Image2" for the second, then describe the swap around those names — for example, "keep the hand and the shelf, replace the bottle with @Image1". Naming the reference removes the guesswork about which uploaded file you meant, and makes it obvious what stays: if you only name the object, the model assumes everything else in the frame should be left as it was.
Object Swap or Motion Transfer?
Use object swap when one element of the frame is wrong and the performer is right — a product that has changed packaging, an outfit that needs a different color, a background that is not the right location. Use motion transfer when the performer is wrong and the shot is right. You can also combine them: download the object swap result, upload it again and run motion transfer on it to hand the performance to a new character.
When Object Swap Works Best
Single objects with clear edges
A bottle, a phone, a cup, a jacket or a car gives the model an obvious thing to find and replace. Objects that blend into the background — a white box on a white wall — are harder to isolate cleanly.
Objects that stay visible
The object needs to be on screen long enough to be seen and stay in frame. A prop that is visible for the full 3 seconds swaps far more reliably than one that appears for a single frame.
Shots without heavy occlusion
If the object is hidden by a hand, a sleeve or another person for most of the clip, the model has less to work with. A clear view of the thing you want to replace gives the cleanest swap.
Object Swap Use Cases
Refresh a product video
A skincare brand filmed a bottle on a bathroom shelf — one take, good light, a steady hand. They swap the bottle for the new packaging and keep the same hand, the same tilt and the same 8 seconds of footage. A fresh ad without booking a studio day.
Update wardrobe and props
Swap a jacket, a hat, a bag or a phone on a performer in a clip you already shot, and keep the walk, the framing and the expression untouched. Useful for a campaign that has to show several colorways of the same garment.
Replace the background
Put the same performance somewhere else — a different city, a different room, a different season — while the subject's movement and the camera path stay exactly where they were.
Credits, Output and Failure Handling
You pay per second of output, and the price depends on resolution: 768P costs 1 credit per second and 2K costs 2. The total appears on the Generate button before anything runs. Pick 3–10 seconds of source footage, choose an output of 4–15 seconds, and if the render does not complete, the credits go straight back to your balance.
Object Swap FAQ
What does object swap do?+
It replaces a specific object in your video — a product, prop, outfit or background — while keeping the camera movement, lighting and timing of the original clip.
How do I tell it which object to swap?+
Describe the change in the prompt, and point at any reference images you uploaded with @Image1, @Image2 and so on. Say what should change and what must stay.
What is the difference between object swap and motion transfer?+
Object swap changes a thing in the frame and keeps the performer. Motion transfer changes the performer and keeps the frame. Restyle repaints the whole clip.
How long should my clip be?+
Upload up to 120 seconds, then select any 3–10 seconds to transform. Short clips swap more reliably.
Can I swap an object in a person's hand?+
Yes, as long as the object is visible in the frame for long enough to be identified. Name it in the prompt, keep the surrounding description simple and say what must stay.
What happens if the render fails?+
Credits return to your balance automatically, and you can retry without paying twice.
