CUE's Light Show supports multiple file formats for on-screen content displayed on fans' phones: PNG and JPEG for static images and logos, GIF for animated content, and MP4 for video files. For colors, simply provide hex codes. Each GIF file must be kept under 5 megabytes; larger files may need compression. The total Light Show package should remain under 20 megabytes to ensure fast, reliable loading across all fan devices, especially in crowded venues where network congestion is common. CUE recommends using transparent PNG files for logos and graphics, as this allows dynamic colored backgrounds to flash and change throughout the show, creating a cleaner visual effect than static full-screen graphics. Content displays at 1080x1920 (vertical/portrait orientation). You can upload multiple images and have them rotate throughout the show at intervals you specify, or keep a single branded graphic displayed for the entire duration. The platform includes a green, yellow, and red warning system when building your timeline to indicate when your total content size may cause issues. For shorter shows (45 seconds), you have more flexibility to include video content or higher-quality graphics. For longer shows (3-4 minutes), be more conservative with file sizes. If you're concerned about file size, consider compressing your video content using Adobe Media Encoder or similar tools, or breaking up longer videos into smaller GIF segments that load between logo displays. Even if on-screen content fails to load due to file size or connectivity issues, the flashlight synchronization will continue to function—fans would simply see a blank screen on their phone while still participating in the light show effect. For venues with known connectivity challenges, CUE recommends sticking with simpler content like logos and colors rather than heavy video files. Your CUE account manager will provide detailed specification guides for all required assets and can help you prepare files in the correct formats.
