Factors that can Affect Sync

to get the best results use enhanced synchronization which is the default setting in brightauthor\ connected and brightwall, but not in {{brightauthor classic}} otherwise, videos will only be synchronized at the beginning and end of playback, and can be up to 1 5 frames out of sync enhanced synchronization communicates during playback to keep the videos synchronized from frame to frame align versions, hardware, and content on all synchronized players use the same brightsignos version on all players if you must use players with different os versions (not recommended), make sure the leader (screen 1 in a brightwall) has the same or older os version as the follower players the presentations must be created in the same brightauthor\ connected or brightauthor classic version if possible, use the latest versions (see the downloads page https //www brightsign biz/resources/software downloads/ ) images that are synchronized between players should have the same size and format videos should have the same resolution and frame rate, and must be encoded at a fixed rate video bitrate should not exceed 25mbit/s for h 264 (avc) videos video bitrate should not exceed 80mbit/s for h 265 (hevc) videos if the leader player has video and audio, the follower players should also have video and audio video and audio must be the same length to the millisecond (if all screens are visible from the same location, drive all the audio from one of the players to avoid out of phase issues on other players) players must be compatible (see audio, videos, images docid\ loevgvyhzty5gpexkt5bb ) use the same microsd cards on all players we recommend class 10 microsd cards to play back synchronize presentations brightsign sd cards http //www brightsign biz/products/accessories/sd cards/ have been tested and proven to work well for synchronized applications transcend cards are not recommended sync over wireless is supported on recent brightsignos 8 x and 9 x versions but avoid multipath if there are multiple active network connections sync traffic should be limited to one network interface, via use of vlans and/or blocking/filtering ptp multicast to synchronize content between multiple players that are also using zone synchronization, make sure to use zone message commands/events rather than link zones commands/events (link zones are limited to the player) if you synchronize players in portrait mode, there are file/media and output restrictions depending on the model see optimize video quality docid\ h730drksg mjtzfmu 1gx for details off board processing by distribution amplifiers/splitters, display/wall processors, and on display processing (scaling, filtering, smoothing) can introduce additional delays and v sync discrepancies older player models if you use hdx10 models for synchronization, ensure that there is no audio track in the video files newer players (hdx20, xdx30, series 2, and newer) can synchronize audio and video, but older players cannot image playback can be sluggish on hdx10 (hd210, hd210w, hd1010, hd1010w), hdx20 (hd220, hd1020) and ls422 players, especially with larger images at 1080p we recommend using videos for sync on those players enhanced synchronization is not supported on hdx10 players we recommend making smaller and shorter videos for these players
