How do I put multiple videos on one screen on TikTok?
TikTok’s own Duet layouts only pair your recording with another TikTok. To show several of your own clips at once, make the collage here and upload the MP4 to TikTok.

Reels and TikTok collage maker
Several clips and photos in one vertical video, built to survive the like buttons and captions. For Instagram Reels, TikTok and YouTube Shorts.
To make a collage reel or TikTok, add your clips and photos above (the editor is already in 9:16), pick a layout, and export a 1080×1920 MP4. Neither Reels nor TikTok has a grid for your own camera-roll clips: TikTok’s Duet layouts and YouTube’s Collab put you next to someone else’s video, not next to your own.
What makes a collage work as a short video is pace. Show one by one in the Timing tab reveals each cell on the beat, so the video builds instead of showing everything in the first second.
How to make a collage reel
Add the clips
Select Add photos and videos and pick three to nine items. Short clips (2 to 6 seconds) work best.
Choose a layout that reads small
Mosaic, Big top, two below and Film strip read well on a phone; a 3 × 3 grid is busy at this size.
Build it with a reveal
In Timing, turn on Show one by one and set Time between cells to match your track’s beat.

Check the safe zones
Keep faces and text inside the dashed box: the striped areas sit under buttons, captions and the username.
Export and upload
Select Export, then Export video. Add trending audio in the app, or bake your own song in under Music.
Reels, TikTok and Shorts: what changes
- Instagram Reels: 9:16 at 1080×1920. Reels can be long, but Instagram says those over 3 minutes aren’t recommended to new audiences.
- TikTok: 9:16. TikTok’s buttons sit down the right-hand side, with the caption and username at the bottom left.
- YouTube Shorts: square or vertical, up to 3 minutes.
A collage here can be up to 3 minutes long, which covers all three.
Sound: bake it in or add it in the app?
Trending sounds only count as "using the sound" when you add them inside the app, so for trend-led posts export with the clips’ own sound (or silent) and pick the track when you upload. For your own music, voice-over or a song you have the rights to, add it in the Music tab and choose Lower under Clip sound to keep voices audible underneath.
