Functional Limitations on MPEG-4
296
VB-C60 supports MPEG-4 format video in addition to JPEG format video.
However, this are several functional limitations as follows.
●
Live Viewing
The following video window settings become disabled, and the frame rate setting of the
camera takes effect.
• Max. Live Frame Rate
• AutoAdjust Frame Rate
Synchronization of audio and video is not guaranteed.
A message is displayed if you attempt to display 21 or more MPEG-4 video windows.
●
Video Recording
The recording frame rate cannot be set for the following recording modes.
• Constant recording
• Motion detection recording
• Sensor recording
The Reduce recording frame rate when disk is under high load setting in the Storage
Server Settings Tool becomes disabled.
Record Now only supports the JPEG format, and cannot record in MPEG-4 format.
●
Playback
Although the following controls can be used when playing back video recorded in
MPEG-4 format, the rewind and nudge back controls do not function.
• Specify playback time using the timeline
• Begin playback from the live event viewing window and event search window
• Pause, fast forward, nudge forward, previous event, next event
If a schedule that had previously been recording in MPEG-4 format is switched to
recording in JPEG format, when rewind playback from the JPEG format time range
enters the MPEG-4 time range, although the rewind playback continues, the video is not
displayed and an error stating “No Recorded Video.” is displayed.
If you attempt to save a time range of recorded video that spans multiple recording
schedules, only the video recorded in the oldest schedule is saved.
The MPEG-4 format video recorded using this software cannot be played back in other
software.
