To blur a face in Premiere Pro, duplicate the clip, apply the Crop effect with an ellipse mask over the face, track the mask across the clip, invert it, then add a Mosaic or Gaussian Blur. It's all built in — great for protecting identities or a stylistic censor look. Here's the full workflow.
How to blur and track a face
Duplicate the clip
Hold Alt (Windows) or Option (Mac) and drag your clip up to a new track. The duplicate holds the blur; the original stays untouched below.
Add a Crop effect with an ellipse mask
From Window > Effects, drag Crop onto the top clip. In Effect Controls, click the ellipse mask icon to place a circular mask, then size and position it over the face.
Track the mask
Go to the start of the clip and click Track Selected Mask Forward. Premiere follows the face frame by frame.
Invert the mask
In the Crop controls, crop in until only the masked area shows, then tick Invert so the effect targets the face rather than the background.
Add the blur
Apply your blur of choice to the top clip:
- Mosaic — the classic pixelated censor. Raise Horizontal and Vertical Blocks for stronger pixelation.
- Gaussian Blur — a smoother, more natural softening. Increase Blurriness to taste.
Use one or the other, not both.
Feather for a clean blend
In the Mask settings, raise the Feather value slightly so the blur's edges blend into the footage instead of showing a hard ring. The result is a clean, tracked face blur that holds up on interviews, street scenes, and stock footage.
Pro tip: if the track drifts when the subject turns or moves fast, scrub to the frame where it slips, reposition the mask, and re-track from there — a couple of correction points keep the blur locked on.
