3×3 Video Wall

Features

Split video or images into a grid of tiles (up to 6×6)
Cut one source into a 1×2, 2×2, 3×3, or custom grid and export each tile as its own MP4 or image file for separate screens.
Bezel compensation — content skips the gap between screens for a seamless picture
Enter your screen bezel width in millimetres and the tool drops the pixels hidden behind each frame, so the picture lines up across the wall.
Live synchronized playback across multiple browser windows
Live Sync mode pushes play, pause, and seek to every tile window over the BroadcastChannel API, keeping all screens frame-locked together.
Support for multi-monitor setups via Window Management API
The Window Management API detects your connected displays and launches each cropped tile onto its own screen for a true hardware video wall.

Frequently Asked Questions

What is a video wall?

A video wall is a display setup where multiple screens are arranged in a grid to show one large image or video. This tool splits your content into tiles so each screen shows its portion of the picture.

What is bezel compensation?

Bezels are the frames around each screen. Bezel compensation skips the content that would fall behind these frames, so the visible picture appears seamless across all screens.

How does Live Sync mode work?

Live Sync opens a separate browser window for each tile. All windows receive synchronized play, pause, and seek commands via the BroadcastChannel API. Each window shows its cropped portion of the source video.

Do I need multiple monitors?

No. Split mode works on any device — it exports tile files you can play on separate screens. Live Sync works best with multiple monitors but can also open windows on a single screen.

What formats are supported?

Video: MP4, WebM, MOV, AVI, MKV. Images: PNG, JPG, JPEG, WebP. For video splitting, output is MP4 (H.264).
