Note:
1. For the MJPEG codec, every frame is key frame.
2. The Key Frame function only works on V8.3.3 or later. If the version of connected GV-System,
through Remote ViewLog, is earlier than V8.3.3, the Key Frame function is not available.
Zoom Function
When you zoom in, the video will be automatically switched to Picture-in-Picture (PIP) mode if the
video resolution exceeds the ViewLog panel. For recordings higher than D1 resolution, you can zoom
up to 32 times the original image size; for recordings lower than D1 resolution, you can zoom up to 8
times the original image size.
A to B Playback Mode
When playing video events, you can set a starting and an ending frame for auto-playing:
1. To set the starting frame A, click the A to B Mode button (Figure 4-4). The message A to B Mode
(Set A) appears on the screen.
2. To set the ending frame B, click the A to B Mode button. The message A to B Mode (Set B)
appears on the screen.
ViewLog will start playing the set frames A to B repeatedly. To stop the playing, click the A to B Mode
button; the message A to B Mode (Cancelled) will appear.
