How to make a picture-in-picture video on iPhone
Picture-in-picture puts a small video on top of a bigger one: your face in the corner of a tutorial, a reaction over a clip, a close-up over the wide shot. In Video Grid Collage any photo or video can float above your main footage as an overlay.
Step by step
Start with the main video
In Video Grid Collage (free on the App Store), tap + on the start screen, choose Image or Video and pick the video that should fill the frame.
Insert an overlay
Tap Insert → Overlay → Image or Video and choose the clip or photo for the small window.
Move and resize it
Drag the overlay into place and pinch to resize it. Guides help it snap neatly to the edges and the center.
Style the window
Select the overlay to round its Corners, add a Border, or tap Remove BG so only the person floats over the video.
Sync the clips and the sound
Line both videos up on the timeline, and use Sound to decide which audio viewers hear.
Export
Export up to 4K in the aspect ratio your platform needs.
Picture-in-picture that looks intentional
- Put the small window where it doesn't cover the action — usually near the top, since platform buttons sit at the bottom.
- Rounded corners or a thin border separate the overlay from the main video.
- For reactions, remove the background from your face-cam clip so you appear right over the footage.
- Several overlays are fine, but keep one clear focus.
