How to put two videos side by side on iPhone
Whether it's a comparison, a duet-style clip or two angles of the same moment, putting two videos side by side is the fastest way to tell both halves of a story at once. You don't need a desktop editor — on iPhone the whole job takes about five minutes with a free video collage app.
Step by step
Get a side-by-side video app
Download Video Grid Collage from the App Store — it's free and built exactly for this: combining multiple videos into one frame.
Import your two clips
Open the app and add both videos from your Photo Library or iCloud Files. Clips can be different lengths and orientations — you'll adjust everything next.
Choose a side-by-side layout
Pick a layout with two frames next to each other. Prefer a top-and-bottom stack instead? There are stacked split-screen layouts too.
Set the aspect ratio
Choose 9:16 for TikTok, Reels and Shorts, 1:1 for feed posts or 16:9 for YouTube. The two frames resize automatically.
Sync the clips on the timeline
Trim each video independently: set in and out points so the right moments play together. This is what makes a side-by-side comparison feel intentional.
Style the frame
Adjust the gap between the two videos, round the corners and pick a background color. Add text labels — for example a caption over each half.
Export and share
Render in high quality (HDR supported) and post straight to your platform of choice.
Tips for a clean side-by-side video
- Keep both clips in the same orientation — two vertical videos side by side fill a 9:16 frame naturally.
- Use a small, even gap between frames; it reads as deliberate design rather than two clips glued together.
- Label the halves with text layers ("Me", "Tutorial", "POV 1") so viewers instantly get the format.
- Play the collage through before exporting to double-check the sync of both clips.
