What is AI Character Swap Video?

AI Character Swap Video is JAI Portal's dedicated tool for replacing any character in a video with a single reference photo. Drop in a clip with a person on screen, drop in a photo of the new character, and the AI re-renders the video with the new character performing the exact same motion, framing, and audio as the original. The result is the cleanest video character swap AI workflow you can run from a browser — no rotoscoping, no After Effects keyframes, no shoot reschedule.

Unlike traditional face-swap tools that paste a face crop onto the original body, AI Character Swap rebuilds the full on-screen character — face, body, outfit silhouette, hair, posture — from your reference image while locking onto the source video's motion arc. When you need to replace a character in a video with AI, this is the right tool: the swap reads as a fresh take with a new performer, not a sticker on top of the old performer.

The page you're on is the working tool. Upload a video (up to 10 seconds), upload a reference image of the new character, click Generate, and the swap renders in about 60–150 seconds. Audio passthrough is on by default, so dialogue, music, and ambient sound stay perfectly synced with the new performance. This is a true AI character changer, built for creators, marketers, and editors who need a real character replacement AI pipeline.

Key Features

Full character replacement from one photo

Face, body, outfit silhouette, hair — all rebuilt from a single reference image. Not a face overlay.

Motion-preserving re-render

Source video's motion, framing, and timing are locked frame-by-frame. The new character does exactly what the old one did.

Audio passthrough by default

Original soundtrack, dialogue, and ambient audio stay synced. Toggle off if you plan to replace audio in post.

Pay-as-you-go, per-second pricing

No subscription. You only pay for the duration of the source clip. Cost shown before you submit.

Watermark-free, commercial-use ready

Every paid generation ships clean MP4 output with full commercial-use rights for ads, music videos, and client work.

Auto-refund on failed jobs

If a render fails, credits return to your account automatically. No support ticket, no manual review.

Pro Tips for the Best Character Swap

Use one clean reference photo, not a collage

AI Character Swap reads identity from a single image. Pick the highest-quality photo where the new character's face and body are both clearly visible — no sunglasses, no extreme angles, no group shots.

Match reference framing to source framing

If the source video shows full body, use a full-body reference photo. If it's a head-and-shoulders shot, match it. Mismatched framing forces the model to invent body parts and can drift.

Trim the source clip to a single continuous take

Multiple cuts or scene changes can produce identity drift mid-output. The model handles one continuous performance cleanly — split longer clips at the cut, swap each, then reassemble in your editor.

Keep audio on for music and dialogue clips

Audio passthrough is on by default — leave it on for TikTok dance clips, dialogue scenes, or music videos. Turn off only if you plan to dub or replace audio in post.

Spin variants by changing only the reference photo

Once a source clip swaps cleanly, treat it as a template. Re-run with different reference photos to spin localized ad variants, casting tests, or multi-character series — the source video stays the same.

Frequently Asked Questions

How is AI Character Swap different from face swap?

Face swap tools paste a face onto an existing body — the body, hair, and silhouette of the original character stay in the video. AI Character Swap rebuilds the entire on-screen character from your reference photo and re-renders them performing the source motion, so the hair, body shape, posture, and outfit silhouette all match the new identity instead of the original.

What's the maximum source video length?

10 seconds per generation. For longer clips, split your source into 10-second segments in your editor, swap each segment separately, then reassemble. The model produces best results on a single continuous take per swap.

Does the original audio survive the swap?

Yes. "Keep original audio" is on by default — dialogue, music, and ambient sound from the source video are preserved on the swapped output. Turn it off only if you plan to add custom audio in post-production.

How many credits does a character swap cost?

Pricing is per-second of source video — see the breakdown under the Generate button (X credits/s × Ys = total). A 5-second swap costs roughly half of a 10-second swap. Corporate accounts get reduced per-second rates automatically. No subscription required.

Can I use the swapped video commercially?

Yes — every paid generation grants full commercial-use rights including for ads, branded content, music videos, and client deliverables. The catch is that JAI Portal grants rights on the AI output, not on third-party content you upload. Make sure your source video and reference photo are either original or properly licensed.

What if the swap doesn't look right on the first try?

Work the inputs before re-rolling: (1) use a higher-quality, better-lit reference photo with face clearly visible; (2) trim the source to a single continuous shot; (3) match the framing of source and reference; (4) make sure the source video isn't shaky or heavily occluded. If you've tried all four, swap to tighter framing on both inputs — the model has fewer degrees of freedom to drift on.

Is uncensored / NSFW character swap supported?

No. JAI Portal is a B2B platform with strict content policies — uncensored, NSFW, and sexually explicit output is not supported. The underlying model has its own safety filters and the platform enforces additional moderation. Use this tool for marketing, music videos, casting tests, branded content, and creative storytelling.

AI Character Swap — Swap Any Character in Video While Keeping the Motion

Drop a video in, drop a character reference photo in, and the AI rebuilds every frame with the new character performing the exact same motion. Full character swap — body, face, outfit, hair, accessories — not a face overlay glued on top.

📄 About AI Character Swap

Most tools sold as "character swap AI" are really just face swap with extra steps. They leave the original body, original clothes, original hair — which breaks the illusion the second the camera pans or the subject turns. JAI Portal character swap AI works on the entire on-screen character: it reads the motion, pose and silhouette from your source video, reads identity, outfit and styling from your reference image, and re-renders the performance with the new character driving the same scene. That is the real definition of AI character swap — and it is what separates a usable production tool from a TikTok novelty filter.

Motion preservation is the part everyone underestimates. A dance clip, a walking shot, a sports highlight, a UGC ad take — they all carry tiny micro-movements that make footage feel real. Our pipeline locks onto those movements first, then transfers the new identity on top, so the swapped character inherits the original choreography frame by frame. Pair it with the AI Video Body Swap workflow when you need just the body swapped, Video Head Swap when you only need the head swapped on existing footage, or AI Image Body Swap and Image Face Swap for still-image identity transfers.

Creators ask whether character swap AI is free. Honestly: free character swap tools exist, but every one of them ships with a watermark, a 5-second cap, a queue, or a clause that forbids commercial use. None of that is acceptable if you are running paid UGC, monetised TikTok, brand content or e-commerce creative. JAI Portal character swap AI is pay-per-use — you only pay for the seconds you render, there is no monthly subscription, no watermark on the output, and you get full commercial rights on every clip. Pennies per render in exchange for clean masters you can ship to a client or push to ads the same day.

Under the hood it is tuned in the same family as the wan 2.2 character swap workflow creators have been asking about — built for video-native identity transfer rather than per-frame face pasting. It handles outfits, jewelry, glasses, hats and hair length changes, holds up under fast motion, and respects the original lighting of the scene. Pair with AI Video Translator for lip-synced multilingual dubs, layer captions via Auto Subtitle Generator, or reframe to 9:16 / 1:1 via AI Video Aspect Ratio Changer before publishing. If the swap calls for changing gender entirely, AI Gender Swap handles that as a dedicated workflow.
