Use an image or video as background
In short
A custom background gives your room screen real identity. Image (Pro plan) or looping video (Premium plan).
1 Background image
- **16:9 format** recommended, 1920×1080 px minimum.
- **Subject contained** in the center or on the sides (the main number takes the middle).
- **Dark overlay** automatically applied to preserve readability.
Ideas that work
A photo of your community hall, an aerial view of the village, a big watermarked logo, a photo from last year's AGM.
2 Background video
- **.mp4 format**, H.264 codec.
- **10 to 30 seconds** on loop.
- **No sound** (audio is not played).
- **50 MB max**.
3 Important precautions
Avoid fast or flashing videos: they tire the eyes and can trigger episodes in photosensitive people. Stick to slow shots, like a drone gliding over a beach.
Did you know?
On older smart TVs a background video can stutter. If you hit this, switch back to a still image — it's always smoother.
