PatchReplacer
Tracked patch replacement
Replaces a damaged or unwanted image region with pixels sampled from a cleaner nearby area, with controls for transform and edge integration.

DaVinci Resolve · Fusion
PatchReplacer is a practical cleanup tool for blemishes, logos, stains, dust or small objects when a suitable replacement texture exists elsewhere in the frame. It works best when the source patch has similar perspective, lighting and texture.
Overview
What PatchReplacer does
PatchReplacer is a practical cleanup tool for blemishes, logos, stains, dust or small objects when a suitable replacement texture exists elsewhere in the frame. It works best when the source patch has similar perspective, lighting and texture.
Mental model
Think of it as a live clone-stamp patch that can be positioned and tracked inside the node graph.
Common uses
Remove small signs or marks
Clone clean wall or floor texture
Repair dust and sensor artifacts
Cover logos or blemishes
Patch small background defects
Create a manual clean-plate correction

Practical setup
A reliable workflow
- 1
Choose a clean source texture near the defect.
- 2
Place the destination over the unwanted region.
- 3
Match scale and angle.
- 4
Feather only enough to hide the seam.
- 5
Track the patch when the surface or camera moves.

Tracked cleanup
Use planar tracking data so the patch follows a moving surface.

Troubleshooting
Common mistakes
Sampling texture with different lighting
Using a patch larger than necessary
Adding excessive edge softness
Ignoring perspective change or parallax
Production notes
Practical tips
Sample as close to the defect as possible.
A small patch is easier to integrate than a large one.
For large or heavily occluded objects, use ObjectRemoval or a dedicated clean plate.
