Common record/play problems
This troubleshooting aid provides corrective action for some common record/play
problems. Search the table for the problem you are experiencing, then try the corrective
action. Some problems have more than one corrective action.
Problem Possible Cause Corrective Action
Application fails to select a
channel or channels when it is
started. Resource conflict because a
resource needed by the channel
is already in use. Check for resources that may be
assigned to more than one
channel and correct the problem
Refer to “Using the Warning
symbol to find shared
resources” on page 124. Also,
make sure the Channel
Configuration dialog box is
closed before running the
application or selecting
channels.
The recorded clip contains
colorbar. The colorbar generator is
selected as the channel input. Select the desired video input as
the channel source. Refer to
“Selecting video quality and
crosspoints” on page 131
The recorded clip contains black
or freeze frame. Loss of input signal. Verify that you have a valid
input signal. Refer to “Viewing
video input status” on page 170.
The channel output is black in
E to E, but playback is fine. Loss of input signal. Verify that you have a valid
input signal. Refer to “Viewing
video input status” on page 170.
Channel output is always black. The output you’re monitoring is
not assigned to the channel. Determine the video output
assigned to the channel by
referring to“Selecting video
quality and crosspoints” on page
131, then verify cable
connections.
Freeze frames or black frames
during playback. The number of record and play,
channels operating
simultaneously exceeds the
system storage bandwidth. Reduce the number of channels
operating at the same time, or
select a lower video quality
preset for the record. Refer to
“Guidelines for selecting Video
Quality Presets” on page 158.
