Swap the character, keep the performance.
Upload your clip and one or two reference images. The AI character swap video tool replaces the person on screen with a full body swap — face, hair, build and outfit — while the original motion stays intact.
What it is
A full body swap, not just a face.
Most tools stop at the face. LazyKiwi replaces the whole person — build, hair and clothing — and tracks them across every frame, so the new character moves and turns exactly like the original take. Use it on footage you shot, with characters you have the rights to.
How it works
Your result in three steps
Upload your video
Pick a clip where the person is clearly visible. Steady framing and good light give the cleanest swap.
Add a reference character
Upload one or two images of the character you want on screen. Clear, front-facing shots work best.
Generate & download
Play the swapped clip back, then download it at the resolution you uploaded.
Frame to frame
The character holds up in motion
Swaps done one frame at a time drift and flicker. This one tracks the subject through turns, walk cycles and hand gestures, so the character stays the same person from the first frame to the last.
- Stable identity across frames
- Handles turns and profile angles
- Body proportions follow the reference
Your call
Two references, one look
Use one image for a straightforward swap, or two when you want the face and the outfit taken from different sources. Your camera work, timing and audio track stay as filmed.
- One or two reference images
- Original audio carried through
- Re-run with a new reference anytime

More answers
More about character swap
How long can the video be?+
Short clips work best. A few seconds up to about a minute keeps the character consistent and the render quick.
Can I swap in a real person without asking them?+
No. Only upload footage you filmed and characters you own or have written permission to use. Don't use it to impersonate a real person.
What if the subject turns away from the camera?+
Profile and three-quarter angles are handled. Frames where the person is hidden or heavily motion-blurred are the hardest, so favour steady shots.
Can I swap two people in the same clip?+
Work one subject at a time. Swap the first person, download, then run that clip through again for the second.
