Playback Mode Option
By default, the ViewLog is set to play back video in the Frame by Frame mode. To change playback
modes, click the
button on the ViewLog Control Panel.
Frame by Frame (without audio): Plays back video frame by frame without audio. Playback can
be delayed depending on the bandwidth and computer performance, but all video frames are fully
played.
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.
Just Key Frame: Plays back the most representative frames of video. When your network
bandwidth is limited, select this option to enhance the playback smoothness.
Smooth Playback: When the playback appears choppy, select this option to enhance the
smoothness.
Note: For the MJPEG codec, every frame is key frame.
