How do I replace a person in a video with AI?

Simply upload a video, add a character image, and let Loova’s AI character swap tool handle the rest. No manual editing required.

What is a character swap video?

A character swap video uses AI to replace a person in a video with a new character while keeping natural movement, expressions, and timing.

What’s the difference between face swap and character swap?

Face swap only replaces the face. Character swap replaces the full body, including posture, movement, and overall presence—making the result far more realistic.

Can I swap characters in videos, not just images?

Yes. Loova's Character Swap feature works for videos, preserving movement, expressions, and timing in video scenes.

Will the swapped character keep the original motion?

Absolutely. The AI transfers the original body movement and gestures, so the new character moves naturally within the scene.

Does Character Swap affect the background?

No. The background remains unchanged unless you choose to edit or replace it separately.

Will facial expressions stay consistent after swapping?

Yes. The AI preserves facial expressions and emotions, ensuring natural and expressive results.

What Makes Loova’s AI Character Swap Video Tool So Powerful?

Swap anyone in a video instantly. Loova’s AI Character Swap replaces the entire person, not just the face, while keeping movement, expressions, and lip-sync natural.

Full Body Swap, More Than Face Swap

Loova goes beyond simple face swaps. With full character replacement, you can swap the entire body, clothing, and posture while preserving realistic movement. This makes it easy to truly replace a person in a video with AI, not just overlay a new face.

Lip-Sync Driven Swaps

Our recast AI technology matches mouth movement and expressions to the original video’s speech and timing. The result is a natural-looking character swap where talking, emotions, and gestures feel authentic.

Motion & Pose Preservation

Loova’s AI understands body motion, posture, and camera perspective across frames. It preserves the original actor’s movements or gesturing, so the swapped character moves naturally without jitter, distortion, or broken anatomy.

One-Click Character Replacement

Upload a video, choose a reference image, and Loova handles the rest. No frame-by-frame editing, no complex timelines. The AI automatically detects the character, tracks them across the scene, and replaces them consistently.
