Swap Who or What
Keep the Motion
Upload a short video. Inflyu swaps in your product, a new person or a new background from a photo or just a description, while the original camera move stays. Free credits on signup.
Most people use it to put their own product into a video
Your first 4-second swap is covered by your free credits. Then credit packs from $1.99.
One swap tool, three targets
Describe what to replace. A photo guides the new look, and a description can be enough.
Person, object, or scene
Prompt the target: the talent, a prop, or the backdrop. On a clip of 4 seconds or more, an object swap, a multi-swap (up to 3 swaps) and a background swap are edited shot by shot at the clip’s cuts and priced per shot and length.
Photo or prompt
Person swaps work from a photo or just a prompt, and so do object and background swaps on clips of 4 seconds or more. A multi-swap needs one photo per swap, and a clip under 4 seconds is a single edit that needs a photo.
Motion stays yours
Blocking and timing come from the source clip. You are not generating a disconnected B-roll.
Prompt the region
Name the cup, jacket, or wall. Vague “make it better” prompts produce weaker swaps.
New file every run
The swapped MP4 lands beside the original. Compare variants without overwriting.
Account-backed jobs
Sign up so credits, retries, and gallery history attach to you — no anonymous generate.
Run a video swap
Register, upload clip + still, describe the target.
Create a free account
Swap jobs need a user for credits and R2 storage.
Upload clip, add a photo or prompt
Name the person, object, or background you want replaced. On a clip of 4 seconds or more a photo is optional for an object or a background; a multi-swap needs one photo per swap.
Save the swapped clip
Download or iterate. The source file stays intact.
AI Video Swap FAQ
What can I swap in a video?+
A person, a product or prop, or the background, or up to 3 people or objects in one multi-swap. Describe the target and add a photo, or just a description (a clip under 4 seconds is a single edit and needs a photo for an object or a background). The rest of the motion stays from the source clip.
Can I use it to make product videos for my store?+
Yes. That is the most common use: take a clip that shows a similar item, upload your product photo, and swap it in. The object swap page covers that flow step by step.
How long can the video be?+
Upload a clip up to 3 minutes — Inflyu uses the length you pick. Ordinary phone footage works; very dark or heavily blurred clips give weaker results.
Do I need a reference image?+
Not for a person, an object or a background: a photo helps the new item, face or place match, but a description works (an object or background swap on a clip under 4 seconds is a single edit and needs a photo). A multi-swap needs one photo per swap.
Is this a face-clone of a celebrity?+
No. Use your own footage and a reference you have rights to. Inflyu is not a celebrity impersonation product.
Why do I have to sign up?+
Video jobs debit credits and store outputs on a user. These pages convert to registration, not an anonymous trial.
How does a swap work on a longer clip?+
On a clip of 4 seconds or more, an object swap, a multi-swap (up to 3 swaps) and a background swap are edited shot by shot: Inflyu splits the clip at its cuts, edits each shot, and prices it per shot and length. The editor shows the credits before you run it. On a clip longer than the swap length you pick, you can choose where the swap starts. A photo is optional for an object swap and a background swap (describe it instead). A multi-swap needs one photo per swap. A clip under 4 seconds is a single edit and needs a photo (person swaps excepted).
How much does an AI video swap cost?+
A person swap is a flat price: 11 credits for 4s, 16 for 6s, 21 for 8s and 40 for 15s. An object, multi- or background swap on a clip of 4 seconds or more is edited shot by shot and priced per shot and length, starting at 12 credits for 4s, 17 for 6s, 22 for 8s and 40 for 15s. Clips with more shots cost more because every shot gets its own edited frame, and the editor shows the exact price before you run it.
Do I need a subscription?+
No. You can pay as you go: credit packs are one-time purchases and their credits never expire. If you would rather have a steady supply, the monthly Starter ($7.99), Creator ($19) and Pro ($49) plans refill your credits each month, and you can cancel anytime. Unused monthly credits do not roll over.
