How to make a picture-in-picture video on iPhone

By Con, founder of Music Wide Selfie · Updated 22 October 2026

Short answerRecord the main clip and the reaction clip separately, then use an editor with picture-in-picture or overlay: put the main clip on the timeline, add the second as an overlay, resize and position it, and sync with a clap.

Record

Film the main clip.
Film yourself reacting, with a clap at the start of both clips.

Edit

Put the main clip on the timeline.
Add the reaction as an overlay or picture-in-picture.
Line up the claps.
Resize and place the small window away from captions.

Or record both at once

Dual-camera recording on supported iPhones saves the sync and editing step.
