Blurring a face in a photo is easy. Video is where most tools fall apart: the blur lags a frame behind, the face drifts out from under it, and a single exposed frame undoes the whole edit. HideFace detects faces and tracks them across frames, so the cover follows people as they move and the camera shakes.
Drop in a clip, let HideFace find and follow the faces it detects, pick a style, scrub the timeline to check it, and export a clean copy. You never keyframe a mask by hand, and nothing you import ever leaves your computer.

Faces found and covered, and the cover follows them as the shot moves
In a still photo a face sits in one place, so a single blur covers it. In video that face moves every frame, the lighting shifts, and the camera drifts. A tool that blurs each frame in isolation tends to lag: the cover arrives a beat late, sits slightly off, or drops out entirely when the person turns. It only takes one clear frame for a viewer to pause the video and see who it is.
HideFace treats a clip as a sequence, not a pile of separate images. It detects faces and follows them from frame to frame, so the cover moves with the person instead of chasing them. That is the difference between a cover that looks deliberate and one that flickers.
The most common way a video edit leaks a face is a stretch of frames nobody watched back. Someone walks in late, turns toward the camera for a second, or appears reflected in a window. Scrub the entire timeline before you export, and pay attention to the moments where a person enters, exits, or moves quickly.
Check anything generated from the video too. A thumbnail, a preview frame, or a platform’s auto-selected cover image can pull from an uncovered moment even when the clip itself is clean.
Blur and pixelate read cleanly while things move and make a safe default. Mosaic and solid give heavier coverage when you want no doubt at all. A black bar suits a fixed head position, like an interview, but can slip if the person moves a lot. Emoji and glitch are stylistic choices for social clips rather than serious redaction.
The free plan exports video up to 15 seconds at 720p, which covers most short social clips. Pro removes the time limit, exports at full resolution up to 4K, and uses your NVIDIA, Intel, or AMD hardware encoder so long clips finish faster. Either way the whole job runs on your computer and nothing is uploaded.
Yes. HideFace tracks each detected face frame by frame, so it stays covered while people move and the camera shakes, not just in the first frame. Detection is automatic and not guaranteed, so review the clip before you publish it.

Pro uses your NVIDIA, Intel, or AMD hardware encoder when one is available, and falls back to the CPU otherwise.
Yes. You can cover everyone, cover only the people you pick, or keep a chosen few and cover the rest.
