How to make a split screen video on iPhone
A split screen video shows two or more clips sharing the screen at the same time — the format behind comparisons, collabs, tutorials and multi-angle edits all over TikTok and Reels. Here's how to make one on iPhone without touching a desktop editor.
Step by step
Install a split screen video maker
Get Video Grid Collage free from the App Store. It handles split screens with 2, 3, 4 and up to 9 clips.
Add your clips
Import from your Photo Library or iCloud Files. For a classic split screen, start with two videos.
Pick the split direction
Choose a left/right split for two vertical clips, or a top/bottom stack when your source videos are horizontal. Both are one tap in the layout picker.
Choose the output ratio
9:16 vertical for short-form platforms, 1:1 for feeds, 16:9 for YouTube — the split adapts to whatever you pick.
Trim each side on the timeline
Every clip has its own track: set precise in and out points so the two sides start, peak and end exactly when you want.
Customize the divider
Control the spacing between frames and the background color that shows through — a thin colored divider makes the split look sharp. Round the corners if you want a softer card-style look.
Export in high quality
Render your split screen video (HDR supported) and share it anywhere.
Which split layout should you use?
- Two vertical clips → left/right split in a 9:16 frame. Each clip stays large and readable.
- Two horizontal clips → top/bottom stack in 9:16. This is the go-to for gameplay + facecam or tutorial + result formats.
- Three or four clips → grid layouts keep every frame the same size; mixed layouts let one clip dominate.
- Use contrasting background color between frames as a visual divider that matches your brand.
