Frame by Frame/Real Time Playback
By default, the ViewLog is set to play back video “frame by frame without audio” for Panorama View,
Quad View and Multi View. To change the playback method to real time with audio playback, find the
“Real Time or Frame by Frame” button on the Playback Control Panel.
„ Frame by Frame (without audio): Plays back video frame by frame. This method delays
playback depending on bandwidth and computer performance, but all video frames are fully
played back. When the view mode is set to be Panorama View, Quad View or Multi View, the
default play mode is Frame by Frame.
„ Real time: Plays back video on real time. This method saves waiting time for rendering, but drop
frames to give the appearance of real-time playback. When the view mode is set to be Single, the
default play mode is Real Time.
