What is AI Character Swap?

AI character swap is a smart editing method that replaces one person (the “source”) with another (the “target”) in a photo or video, without rebuilding the whole scene. In practice, you give the tool two inputs: the clip or image you want to change and the character you want to insert. The AI then tracks pose and motion, masks the original subject, maps the new character onto the same position, and blends textures, lighting, and shadows so everything looks like it was shot that way.

It works for both photos and videos: still images are swapped in one pass, while videos are handled frame by frame to keep expressions and movement natural. The big advantages are speed (seconds to minutes, not hours), consistency (same character across multiple shots), and control (backgrounds, props, and timing stay intact). You get believable results for social content, mockups, demos, or playful remixes, without advanced editing skills.

What Can AI Character Swap Do?

AI character swap opens up creative possibilities across both video and photo editing:

• Retouch photos with creativity

In photos, it serves as a tool for creative retouching, blending a new character seamlessly into family portraits, product shots, or artistic compositions.

• Personalize your video making

On social media, it’s a way to personalize or add humor to your content: make a fictional hero dance, put a friend into a trending meme, or replace yourself in a viral clip.

• Perform classic film scenes

For film lovers, it lets you re-cast iconic scenes, placing your favorite actor, or even yourself, into a movie moment while keeping the original camera work intact.

>>Pro Tips

• Use consistent lighting between the character image and the base video for better blending.
• Prefer medium shots (waist-up) and non-occluded subjects; overlapping arms/props can confuse tracking.
• If motion is complex, try a shorter clip first; then upscale to a longer scene.

How to Swap a Character in a Photo

We will use Galaxy AI character swap tool as an example:

Step 1.Upload base photo + target character photo. The tool blends your target into the base scene.

Step 2.Refine settings (if available). Keep posture, scale, and face angle coherent.
