Part 1: Capcut: A Professional Video Editing Tool

Launched in 2020, Capcut has become a popular video editing tool due to its mobile-friendliness and ability to make professional-quality video editing features accessible to everyone, even if you don’t have a computer.

One such feature is the blur effect which allows you to obscure faces (or objects) in videos by applying a customizable blur effect. This tool delivers precision and simplicity, making it a valuable asset for content creators and casual editors.

Capcut’s blur face tool provides flexibility in how much you want to blur out a face. The blur opacity is adjustable, allowing you to choose how opaque or transparent the blur appears. You can also adjust the blur size to cover more or less of the subject’s face or extend the blur area to blur out additional parts of the video.

Another upside of this blurring feature is that you can use it alongside other effects like auto subtitles, transitions, or overlays without slowing down your workflow.

The blur face feature is available across all platforms, including iOS and Android, and is optimized for mobile devices. Canva’s lightweight design ensures smooth performance, even on devices with lower processing power, so you can still access it even if you don’t have a high-end smartphone or tablet.

In addition, the Capcut blur face feature remains available in the free version, so you can explore this feature without needing to upgrade. Keep reading to learn how to blur faces in Capcut.
