Replace anyone in a videowith a single photo
Upload a clip and a photo. oVideo puts the person from the photo into the video: same moves, same camera, same sound. Their face, hair, body and outfit come from your photo.

How it works
Swap a character in three steps
- 01
Upload your video
Any clip up to 60 seconds: a dance, a movie scene, a sports moment, your own footage. Then pick the 3 to 15 seconds to swap.
- 02
Add one photo
A clear photo of the new person, face visible. Waist up or full body works best, because the outfit comes from the photo.
- 03
Create
The AI copies the motion and camera onto your person and puts the original sound back. The video lands in your gallery in a few minutes.
Character swap vs face swap
More than a face swap
A face swap pastes a new face onto the old body, so the hair, build and clothes still belong to someone else. A character swap replaces the whole person. Your friend shows up with their own haircut, their own build and the jacket from their photo, moving exactly like the person in the original clip.
Everything around the person stays: the background, the lighting, the camera moves and the timing. That is what makes the result read as the same video with a new star, which is the whole joke of most viral remakes.
Ideas
What people swap into
- Viral dances and challenges. Put yourself or a friend into the trend instead of learning the moves.
- Movie and TV scenes. Recast a famous scene with your own face for a birthday or a group chat.
- Sports highlights. Score the goal, sink the shot or land the trick yourself.
- Brand and creator content. Reuse one strong clip with different presenters or mascots.

Answers
Frequently asked questions
- How do I replace a person in a video with AI?
- Upload the video, pick the 3 to 15 seconds you want, add one clear photo of the new person and press create. oVideo copies every move, the camera and the timing from your clip onto the person in the photo, then puts the original sound back.
- Is this a face swap?
- It goes further than a face swap. The whole person is replaced: face, hairstyle, body shape and the outfit from your photo. The background, camera movement and motion stay from the original clip.
- Does the video keep its sound?
- Yes. The audio of your original clip, music or speech, is added back to the finished video, in sync with the motion.
- How long can the video be?
- You can upload a clip up to 60 seconds and 200 MB, then choose any 3 to 15 second part of it to swap.
- How much does an AI character swap cost?
- It is priced per second: 19 credits per second at 720p and 26 credits per second at 1080p. A 10 second swap at 720p is 190 credits. The price is shown before you create, and failed videos are refunded automatically.
- Which AI model does it use?
- Kling 3.0 Omni, with your clip as the motion reference and your photo as the reference image.
- Can I swap in a friend or a celebrity?
- Only use photos of people who agreed to it. Before every video you confirm that you have permission from the person in the photo.
