Face detection
Also known as: face finding, face tracking
AI that finds human faces in images and video and marks where they are. It differs from face recognition, which identifies who a person is.

What it means
Face detection answers a simple question: is there a face here, and where? It draws a box or points around each face in a frame, without knowing whose face it is. Face recognition is a separate step of computer vision that compares a face to known identities, which raises much bigger privacy questions.
Cameras use face detection to set focus and exposure on people, gimbals use it to keep a vlogger centered, and editing tools use it to reframe shots around faces or find moments where people appear. Faces are strong signals of human interest, so they matter for choosing highlights too.
Detection works best on frontal, well-lit, unobstructed faces.
How it works in practice
In action footage, helmets, goggles, masks and motion blur often hide faces. Clips from before and after the action, such as smiles at the bottom of a run or a reaction shot, usually give detectors the clearest view.
For vlogs on a pocket gimbal or with a phone, face tracking keeps the speaker framed while walking. Good light on the face improves reliability, and so does keeping the camera at a steady distance.
Editing tools can use face positions for auto-reframing to vertical formats, keeping people in frame when cropping a wide shot.
What to watch out for
Detectors can miss faces in profile, in shadow or far away, and can mistake patterns for faces. Results are good on average but not perfect on every frame, so features built on them, like tracking, can stutter.
Face detection in public footage raises privacy concerns, especially when combined with recognition. Be careful with footage of strangers, and follow local rules on publishing people, especially children.
Detection can be less accurate for some groups if training data was unbalanced. Responsible tools test for this, but it is worth keeping in mind when relying on automation.
How RawClip handles it
RawClip uses AI analysis that considers faces along with motion, jumps and peak action when it picks moments. It does not identify people, and your footage is never used to train models. The result is one highlight synced to music.
