YouTube videos are horizontal 16:9, so the trick is to choose a layout that suits your clips.

In Video Grid Collage, tap **Video** under **YouTube** on the start screen, or pick a layout in the **Landscape** section, add your clips, sync them on the timeline and export in up to 4K at 60 fps. **You'll need:** an iPhone (iOS 18+) · the free [Video Grid Collage](https://apps.apple.com/app/apple-store/id6743649992?pt=123926799&ct=en-youtube-16x9&mt=8) app · ~5 minutes ## Step by step ### 1.
