mimicA split-screen UGC video puts you in the top half of the frame and your product in the bottom half: app screens, a website, photos or a demo clip. You keep talking to camera the whole time while the panel below changes every few seconds.
To make one, film yourself with room above your head, collect four to eight screenshots or clips, and stack them under your take. Put a short title on the dividing line and keep captions just above it.

Why the format works
The usual talk-plus-demo edit cuts away from your face to show the product, then back. Every cutaway is a moment the viewer loses the person they were listening to. A split screen does both at once: your face carries the trust, the panel carries the proof.
It also front-loads the product. TikTok tells advertisers to introduce what the video is about in the first three seconds (TikTok Ads Help Center, 2025). With a split screen the product is on screen in the first frame.
The layout
| Zone | What goes there |
|---|---|
| Top half | You, framed so your face sits near the middle of the half, chin well above the line |
| Just above the line | Captions, one or two words at a time |
| On the line | A short title: the hook or the product name, small enough not to cover either half |
| Bottom half | Screenshots shown whole on black, or demo clips filling the panel |
Keep the title and captions inside the platform safe zone. The bottom of the screen is covered by the caption and buttons; see safe zones.
Filming for split screen
- Leave headroom. Only the top half of your video survives, so frame a little wider than usual with your eyes about a third of the way down.
- Don’t film too close. A very close face leaves no room under the chin for captions.
- Talk about what will be shown. “Here’s the screen where you…” lines give each picture a reason to appear.
- Collect the panel material first: four to eight screenshots or short screen recordings. Tall phone screenshots work well; wide images get small.
Pacing the panel
The most common mistake is one screenshot held for the whole video. Treat the panel like cuts:
- Change it every 4–6 seconds.
- Show a tall screenshot in beats: the whole thing, then its top, then its middle.
- If a picture has nothing more to show, push in on it slowly.
- Match changes to what you’re saying: a new screen when you mention a new feature.
Making one with Mimic
- Pick a split-screen style, or copy one from a video that uses it.
- Add your take and your screenshots or clips.
- Mimic frames you in the top half, fills the panel with your pictures one after another, changes them every few seconds, writes a title for the line and captions every word above it.
- Change anything in the editor, or ask the AI.
The video in this page’s first example is a real Mimic split screen: a creator’s raw take with his app’s App Store page and screens in the panel.
Questions
What is a split-screen UGC video?
A vertical video split across the middle: the creator talks to camera in the top half while the bottom half shows what they're talking about, such as app screens, a website, product photos or a demo clip. Viewers see the face and the product at the same time, so nothing has to cut away from the speaker.
When should I use split screen instead of B-roll?
When the product is on a screen (an app, a website, a dashboard) or when you have lots of pictures to show. B-roll cutaways hide your face; split screen keeps you in view the whole time, which suits talking-heavy videos and testimonials.
How do I frame myself for split screen?
Leave headroom and keep your face in the upper part of the frame. The top half of a 9:16 video is roughly a square, so your face and shoulders need to fit there, with room under your chin for a line of captions.
How often should the bottom panel change?
Every few seconds. A picture that sits still for 15 seconds goes stale. Change it every 4–6 seconds, or move across one tall screenshot (its top, then its middle) so the panel keeps moving.
Can Mimic make split-screen videos?
Yes. If the style you pick uses a split screen, Mimic frames you in the top half, fills the bottom with the pictures and clips you add one after another, puts a small title on the line and the captions just above it.
