What is picture in picture?
By the KeyMo team · Updated
Picture in picture (PiP) is a small video window shown on top of a larger one. Editors use it for reaction shots, guest windows and screen shares. Phones and browsers also use the same words for a mode where a video floats above other apps. In a 9:16 clip, the narrow frame leaves little room for the inset.
Picture in picture meaning: two uses of one phrase
In editing, picture in picture is a layout: one video fills the frame and a second, smaller one sits on top, usually in a corner. A reaction channel puts the creator's face in a small box over the video they are reacting to. An interview can show the guest large and the host in a small window. A tutorial can show the screen large and the presenter small.
On devices, the same phrase names a viewing mode. You start a video, leave the app, and the player shrinks into a small window that floats over whatever you open next. That is a feature of your phone, TV or browser and of the app that plays the video, so what you get on YouTube or Instagram depends on your device and app version. It is not something you add while editing, and a clip you export does not carry it.
Picture in picture on a 9:16 frame
A landscape layout has room for an inset that stays out of the way. A vertical frame is 1080 pixels wide and 1920 tall, so a window that is a third of the width is only 360 pixels across. It also has to share space with captions and the platform's buttons.
Meta's guidance for Reels ads, which is the clearest published rule for placement, says to leave roughly 14% of the top, 35% of the bottom and 6% on each side free of text, logos and other key elements. Apply that to a 1080x1920 frame and about 269 pixels at the top, 672 at the bottom and 65 on each side are off limits. The usable area is roughly 950 pixels wide by 979 tall. That is advice for ads, so treat it as a careful starting point for ordinary posts, not a rule for them.
| Placement | Good for | Problem |
|---|---|---|
| Top corner | A small reaction face | The top strip can be covered by the app's interface |
| Middle, under the main speaker | Two people in a conversation | Eats into the main picture and the captions |
| Bottom corner | Rarely good | The bottom is where captions and buttons live |
Alternatives and when to skip it
If the second video matters as much as the first, stack them instead. A split screen gives each person half the height and avoids a tiny face. If the second video is only decoration, drop it: a cutaway or a text overlay is cleaner.
- Use PiP when the viewer needs to see a reaction to something specific, like a screen or a video.
- Skip it when the inset would be too small to read an expression.
- Skip it for a standard two-person podcast, where the speaker who is talking can simply fill the frame.
Mistakes people make
- Placing the inset where captions will land.
- Making it so small that it only adds clutter.
- Leaving it on screen for the whole clip when it is only useful for a few seconds.
- Forgetting that the app's own interface can cover parts of the top, bottom and sides of the frame.
Where KeyMo fits
KeyMo turns a long video into vertical 9:16 clips and uses automatic face-tracking to reframe the picture around the speaker. That is a single-shot framing, not an inset layout. If you plan to run a picture-in-picture layout, preview the clip before you export it.
