Part 1. Understanding Face Blurring Techniques

Manual Face Blurring

How can I blur a face in a video? The first to make a picture less blurry and most common technique used to blur a face in a video is called the manual face blurring technique. From the word itself, 'manual' means that the users or editor of the video will have to manually apply a blur effect or filter to a person's face in the video frame-by-frame, by applying a blur effect by creating a mask around the face, and from there, the user will have to position the mask using the keyframes frame-by-frame. While this method provides coverage and accuracy when blurring a face, it is time-consuming and is not recommended for videos with more extended footage that contain more movements.

Automatic Face Blurring

How do you blur out a face in a video? Another face-blurring technique that is more efficient to use is the automatic face-blurring technique. This technique is now being integrated and used in a video post-processing editor tool powered by AI, which automatically analyzes a video's face subject and applies a blur effect to the selected face, following it throughout the video. This makes the task easier, as it is fast and instantaneous, eliminating the need to manually select a face and create a mask frame by frame, like manual face blurring, which consumes a lot of time.
