How to use it
- 1
Pick a frame
A screenshot of your shot, or the video itself (scrub to a typical moment).
- 2
Mark the face
Drag a box around the head. Make it cover where the head moves during the take, not one still.
- 3
Move the caption
Switch to Move the caption, drag it, and pull the corner handle to resize.

Read the verdict
Red when it touches the face (plus the breathing room you set) or a platform's UI area. Green when it's clear of both.
Where text goes in a talking-head shot
In a close shot the face fills the middle of a vertical frame, and the app's UI owns the bottom third and the right edge. That leaves two homes for text: the band above the head (hooks, titles) and the band between the chin and the bottom safe zone (captions).
If the face sits low in the frame, there's room above it. If it's high and close, captions go below the chin, which is why tight framing with the eyes about a third from the top leaves the most room.
Worked example
A close-up where the face spans 22% to 48% of the frame height.
A caption at 36% covers the mouth: red.
Tap Under the face: it moves to about 52% (below the chin plus 3% room), above TikTok's bottom zone at 65.6%. Green.

Questions
Does this detect faces?
No. You mark the face yourself. Nothing is analysed, so it works on any frame and nothing about your face is processed or sent anywhere.
Why keep captions off the face?
Viewers read the speaker's expression and lips. A caption over the mouth hides both, and a hook over the eyes covers the most-watched part of the frame.
What's breathing room?
Extra space around the face box, as a percentage of the frame, so text doesn't sit right against the chin or hairline.
Which safe zone should I check?
The platform you post to most. The safe zone checker shows all three at once.
Does Mimic do this automatically?
Yes. Mimic keeps captions, hooks and cards off the speaker's face and inside the apps' safe zones when it edits your clip.
