The DV Rack Components
The DV Quality Monitor and Clip Alerts
The DV Quality Monitor allows you to set allowable limits for audio and video
signal ranges. When your signals exceed these thresholds, Clip Alerts are
displayed in the DVR.
Video Clipping Alerts
Video clipping can occur when a quick, bright flash appears in your video such as
when a car with shiny hubcaps speeds by and momentarily catches the sun’s
reflection. You may not see the flash while you record but DV Rack will catch it
and display it as a video clipping alert in your DVR. You set the allowable luma
level, sample area and event duration thresholds and video Clip Alerts tell you
when your video quality exceeds all three threshold settings.
Audio Popping Alerts
Audio Pop Alerts indicate sudden or “popping” noises (sometimes associated
with “p” sounds in talent’s speech) or sudden level changes. You set the level of
“pop sensitivity”.
Turn Audio Clip Alerts On or
Off
Drag the sliders up or down to set threshold levels for
Video clipping and Audio Popping
Video Clip Alerts appear as yellow bars that run through the
middle of the green audio wave form in your clip. When you
see a Video Clip alert, this indicates that there may be clipping
in your video and your picture may be distorted.
Audio Pop Alerts appear as rectangular blocks along the
audio signal in your clip. Pop Alerts identify sudden surges in
sound that don't clip but are likely to result in unpleasant and
possibly, unusable audio.
