Synchronize videos with events Aim To synchronize the MediaRecorder videos with the event log of The Observer XT. When is manual synchronization not needed? Videos created by MediaRecorder are automatically synchronized with the events in The Observer XT when you followed the procedure in  MediaRecorder with The Observer XT . An automatic offset is applied to the videos. See  View the automatic offset of videos imported into The Observer XT  to see which offset was applied. When is manual synchronization needed? You need to synchronize videos and events manually in the following situations: You start video recording manually and import the videos into The Observer XT. You have an older version of The Observer XT that does not support N-Linx data transfer. See  Synchronize manually for the procedure.
