Yes, PostUP supports video backgrounds that automatically loop behind your fan photos. You can upload an MP4 video file (H.264 encoded recommended) as your background instead of a static image. For best performance, keep the video file compressed and relatively short — a three-minute loop would be quite large to load, so shorter, well-compressed loops work best. Simply upload your video file in the mainboard uploads section, and it will continuously loop behind the rotating fan photos. Many teams find that a subtle textured or motion background makes the overall display look much more polished and professional, especially when the content is displayed for extended periods.
