What is AI character swap?

AI character swap replaces the person or character in an existing video with a different one, while keeping the original motion intact. Unlike a face swap, which only re-skins the face, a character swap can change the whole subject and still follow the movement of the source take.

Can I swap characters in a video for free?

Yes. New CloneViral accounts start with 200 welcome credits, which is enough to swap characters in your first videos without paying. After that the tool runs on credits, which are included in every subscription plan.

Does AI character swap work on the full body or only the face?

Full body. Replace Character mode swaps the entire subject — body, clothing and face — rather than compositing a face onto existing footage, which is why the result holds up on wide and mid shots as well as close-ups.

What is the difference between character swap and face swap?

A face swap only replaces the face and leaves the original body, clothing and build in place. A character swap replaces the whole subject while following the original motion, so you can put a completely different character into a take instead of just changing whose face appears.

Can I animate a photo instead of swapping a character?

Yes. Photo Animate mode takes a still image and drives it with the motion from a reference video, so a photo performs the movement in the clip. It uses the same two uploads as character swap — an image and a video — but applies the motion to your photo instead of replacing the video subject.

What video formats and file sizes are supported?

Standard video and image formats are accepted, and each uploaded file must be under 100MB. For the cleanest character swap, use footage where the subject is clearly visible and not heavily occluded.

How to swap a character in a video

Swapping a character takes three steps and no editing experience. Upload the video you want to change, upload an image of the character you want in it, and generate — the AI keeps the original motion, timing and camera movement of your source take.

Upload the target video

Upload the video containing the character you want to replace. Files must be under 100MB, and the subject should be clearly visible in frame.

Upload the new character image

Upload an image of the character you want to swap in. A clear, well-lit full-body reference gives the most consistent result.

Generate the character swap

Select Replace Character mode and generate. The AI swaps the character while keeping the original motion, timing and camera movement of your source video.

Character swap FAQ

Common questions about AI character swap, how it differs from a face swap, and what the tool supports.

Upload the video you want to change, then upload an image of the character you want in it. Pick Replace Character mode and generate — the AI maps the new character onto the original performance, so the motion, timing and camera work of your source clip are preserved. No masking or keyframing is required.
