How to Do AI Video Person Replacement in 3 Simple Steps

Swap the full person in a video while keeping the scene. Follow these quick steps in Pixelfox AI.
Step 1
Upload a Reference Character Image
Choose a clear portrait or full‑body image of the new character. A well‑lit shot works best. Try to match camera angle and general pose to your scene for a tighter Character Swap. Tip: you can add an optional clean first frame plate to improve occlusions.
Step 2
Upload the Driving Video
Pick the clip you want to re‑characterize. Aim for steady framing and natural motion. Avoid hard cuts inside one shot. Select the Full Body Swapping preset to enable Role Replacement across body, outfit, and hair, not just the face.
Step 3
Generate, Review, and Download
Click Generate. Turn on Temporal Consistency to cut flicker. Use Scene‑Light Match to lock color and grade. Enable Occlusion Shield if hands cross the face. Export in HD or 4K and share your AI Actor Replacement anywhere.

Pose & Body Segmentation Engine

We track full‑body motion, not just facial landmarks. This powers AI Body Swap and AI Actor Replacement that holds up during movement, partial turns, and casual gestures.

Scene‑Light Match & Grade Lock

Keep the set, lighting, and grade you already shot. Our color lock blends skin tones, fabric, and reflections with the original environment for a natural Role Reversal.

Temporal Consistency Controls

Reduce flicker and jitter with a single toggle. Stabilize fine details like eyes and lips for cleaner Video Re-Characterization across the full shot.

Occlusion Shield & First‑Frame Plate

Hands over faces? Props in front? Enable Occlusion Shield. Optional first‑frame background plate helps the model reason about what lives behind the actor you replace.

Identity‑True Character Swap

Guide the output with a single reference photo. Keep the hairstyle, outfit cues, and facial structure of your character while the video’s scene stays intact.

We give you consent prompts, clear usage flags, and private processing by default. Use Pixelfox AI responsibly for Replace Person workflows that meet policy.
