Video Sync

these pages discuss the advanced sync concepts for a more general overview of video synchronization, see video sync overview docid\ mlhkos5yd5fricge0rckd brightsign players can synchronize their clocks; synchronize videos playing in zones; and jam sync, frame sync, and hdmi clock sync work behind the scenes to make sure that videos start at the same time, continue to play and sync, and are drawn to the screen all at the same time these synchronization features are described below screenshot 2024 02 13 at 10 20 53 am png player sync synchronized brightsign players communicate over ethernet when you have more than one brightsign player connected and synchronized, their clocks will be synchronized using ptp synchronization (see video wall synchronization architecture docid 2tw5hfk9u5tjdwf8x 1s3 for more detailed information) the leader player will set the pace for the follower players synchronization over wifi is not supported, and different player models (for example, the hd and xd) should not be synchronized since performance varies between models zone sync zone synchronization can be done in one player or across multiple players one zone and its associated video player is a leader and the other zones, with their associated video players, are followers this can be done all on one player, which doesn't require clock synchronization, or it can be done across multiple players which requires the synchronization of clocks, zones, and videos video sync features these features synchronize videos across players and zones behind the scenes to ensure that videos start at the same time, stay in sync across playback over time, and that the videos are drawn to the screen in the same way so that they're always in sync jam sync this forces the videos to start at the same time with the leader directing the followers frame sync the leader sets the pace for the playback video and the followers adjust their playback either by speeding up or slowing down on a frame by frame basis so the video is always in sync hdmi clock sync when the video leaves the hdmi outputs of one player or multiple players, the hdmi output clocks are in sync so each line of the video is drawn to the screen at the same time sync options these four methods can be used to create synchronized presentations brightwall™ this brightauthor feature allows you to create and publish looping video playlists for video walls (images cannot be included in the playlist) it is only available in versions 3 8 0 x and later and is not available in brightauthor\ connected see brightwall presentations docid\ yof9 porjy87iukgt8pv for more info brightwall has the following features tools to generate video wall content by splitting up a single video or integrating several video files into a synchronized wall you can save the video wall project as a single presentation file you can publish using standalone or local file network, without separate publishing steps for each player in a deployment advanced ip configuration is not required for most networks brightwall drawbacks include you can only create simple looping playlists there are no options for interactivity only mp4 and ts video file formats are supported (images cannot be included in the playlist) autowall the autowall plugin kit allows you to publish video walls that automatically resize to fit the number of players in the wall autowall presentations play videos from dynamic playlists docid\ lfmkbxpuqwc5t2osx8gix or mrss feeds (any image or audio files that are part of the feed will be ignored), and also supports a multi screen ticker option see this page docid\ pmovu0xw5oubjalyddiod for more info enhanced sync this feature, in brightauthor\ connected and versions 3 8 0 x and later, allows leader and follower synchronization events to execute within a few milliseconds of each other also, though enhanced sync presentations can be more complicated to create and publish than brightwall presentations, they let you create an interactive presentation that include synchronized videos see this page docid\ kuvhcsc jotyfetq o8yh for more info on this feature in brightauthor\ connected when using players with different brightsignos versions (which is not recommended), make sure the leader has the same or older os version as the follower players link zone sync this older method is a very simple way to synchronize zones (images and videos) within a presentation additional resources standard (linked / sync'd) videowalls docid\ kuvhcsc jotyfetq o8yh multiscreen video playback docid\ k9hptp4rvebnegdeegrjp for xc2055, xc4055, and xt2145 players
