AI Face Swap Video: Inputs and Workflow | FluxoKit Docs

Replace the main actor in a video with the character from an image. The scene stays, the face and body change. Same canvas that creates and edits video, pay cents per generation.

Why Run AI Face Swap on FluxoKit

Swapping the character in a video usually means frame-by-frame edits or expensive English-only VFX tools.

On FluxoKit you upload a reference image of the new character plus the source video, and the model rebuilds the scene while keeping motion and framing. No video editor, no VFX, same plan that unlocks 90+ other models.

How to Use

1. Open the studio at /workflow.
2. Pick AI Face Swap in the video editing category.
3. Upload the reference image and the source video.
4. Generate. You get the same scene with the new character in seconds.

Use Cases

• UGC - reuse a winning video by swapping the creator.
• Info products - keep a consistent digital character across courses or VSLs.
• Localization - adapt the on-screen actor for a different market.
• Creative testing - vary the face of an ad without reshooting the scene.

What Makes a Good Swap

The model rebuilds a scene around a new character, so two inputs decide the result: a clean reference image and a clear source video. A reference with a well-lit, front-facing subject gives the model the most to work with. A source video with one obvious main character and steady framing swaps more cleanly than a crowded or fast-cut scene. Short reference clips with the actor clearly visible deliver the most consistent output. Scenes with several faces, heavy motion blur, or rapid cuts are the hardest to swap cleanly, so a single, steadily framed lead is the safest source.

What Stays and What Changes

The swap preserves the scene's motion, expression timing, and framing while replacing the face and body of the lead. A clip you already know performs can be reused with a different actor instead of reshooting it. The camera move, the pacing, and the edit stay intact, so the new version drops straight into the same slot.

Keep One Character Across a Series

Reuse the same reference image to apply one character across many videos. That is how you keep a consistent on-screen identity for an ad set, a course, or a content series without booking the same person for every shoot. Generate the variations you need and the look stays coherent across the whole campaign.

Where Character Swap Fits

Face swap is an editing step, not a generation engine. Create or source the base video first, with Seedance, Kling AI, or your own footage, then swap the lead. For a fully synthetic presenter instead of a swap, the AI Avatar Generator is the better starting point. Run the swap last, after the cut is locked, so the new character carries the final timing and you are not re-swapping every revision.
