Blur an Entire Video or Manually Selected Region

Nujiz Blur Video hides visual detail using a pixel-blur effect. Apply it to the complete video or position a rectangular region over a specific area and resize that region until it covers the content you want to obscure.

Blur a selected region

In manual-region mode, drag the selection over the video and adjust its X position, Y position, width and height. This is useful for obscuring a fixed area, but the region does not automatically track a moving face or object.

Choose blur strength

The interface provides Light, Medium, Strong and Very Strong settings. Higher strength makes details inside the selected area harder to identify. Review the preview and choose a level appropriate for the content.

Blur is different from object removal

This tool visually obscures content and does not reconstruct the background behind an object. Removing a mark and rebuilding its surrounding area is a different type of processing.
