The process of publishing BrightWall presentations differs from publishing standard presentations. See the Publishing a BrightWall Presentation page for more information.
For best results, we recommend using the .mp4 or .mov container for video files that make up a BrightWall presentation. Transport Stream (.ts) files are also supported, but they must begin with a presentation timestamp (PTS) offset of zero. Program Stream (MPEG-PS) files are not supported.
It is possible to create a seamlessly looping video wall if the video files are formatted appropriately. See the Seamless Looping FAQ for more details.
