Blur vs Pixelate: Which Should You Use to Redact a Video?
June 21, 2026
When you redact a video, you usually have two choices: a soft blur or a chunky pixelate (mosaic). They look different and, more importantly, they aren't equally secure. Here's how to pick.
The short answer
For anything genuinely sensitive — text, faces you must protect, license plates — prefer a strong pixelate or a solid block. A light blur can sometimes be partially reversed or read, especially on text and small details. Blur is fine for cosmetic or low-stakes hiding.
Blur
- Looks natural and unobtrusive.
- Good for softening backgrounds or de-emphasizing something.
- Weak setting on text/plates can leave traces — always use a high strength for sensitive content.
Pixelate
- Clearly intentional — signals "this was redacted on purpose".
- Large blocks destroy detail, making recovery much harder.
- Preferred for documents, screens, and plates.
Solid block: the safest option
When in doubt, a solid block removes the underlying pixels entirely — nothing to recover. It's the most secure choice for high-stakes redaction.
