Tips for the best result

  • Pixelate at strength 6+ makes text completely unreadable.
  • Trim the video into parts if the subject moves a lot, and blur each part.

Blur / pixelate — FAQ

Does the blur follow a moving face?

The boxes stay where you put them. For something that moves, make the box a little bigger or trim the video into parts.

Is the blur reversible?

No — the hidden pixels are replaced in the exported file, so the original detail cannot be recovered from it.

How many areas can I blur?

Up to eight boxes, each with its own position and size.

Does the blur follow faces automatically?

Not yet — boxes are fixed. This keeps everything on your device with no AI upload.

Is the hidden area recoverable?

No. The pixels are replaced in the exported file.
