Performance-Driven Prop Replacement

This workflow lets you replace any prop in a video—like a watch, bottle, phone, or product—while keeping the original performance exactly the same.

You don’t need to reshoot anything.
The system updates the object, but preserves every detail of the actor’s movement:

✔ Same face and expressions
✔ Same hand motion
✔ Same timing
✔ Same body performance

Only the prop changes—cleanly and consistently.

How It Works

1. Turn on Qwen (the Image Editor)

Qwen acts like Photoshop for a single frame.
It lets you modify the first frame of the video, replacing the original object with the new one.

2. Select the Area That Needs Replacement

Load the first frame and highlight the region:

• the wrist

• the hand

• the table

• or wherever the prop is located

This tells the system:
“This is where the new item will appear.”

3. Describe the New Prop

Tell Qwen exactly what should replace the old object.

Examples:

• “gold luxury watch on the wrist”

• “sleek black smartphone in hand”

• “matte black perfume bottle on the table”

Qwen generates a clean, realistic edit with proper:
✔ angle
✔ lighting
✔ shadows
✔ reflections
✔ proportions

4. Send This Edited Frame Into Wan2.2

The edited frame becomes the reference image.
Wan 2.2 understands:
“This is the new object—keep it stable in every frame of the video.”

5. Upload Your Original Video

Your raw video supplies all the natural body motion:
✔ hand movement
✔ wrist rotation
✔ expressions
✔ timing
✔ gestures

Wan 2.2 uses this motion data so the performance stays 100% original.

6. Activate Wan2.2 Animate

Wan 2.2 rebuilds the entire video with the new prop integrated frame-by-frame.

The result:
✔ No flicker
✔ No jitter
✔ No warping
✔ The prop stays locked to the hand/wrist
✔ Motion stays perfectly natural

🎬 Final Result

You get a seamless video where:

✨ The original prop is fully replaced
✨ The new object looks physically correct
✨ The movement, expressions, and performance remain untouched
✨ The replacement stays consistent across the entire clip

The final output looks like the video was shot with the new prop from the beginning.
