Audio Clipping Alerts
Audio Clip Alerts indicate the presence of sounds beyond the recording range of
your microphone. This type of audio clipping may or may not be audible on loca-
tion but can cause problems when editing. You can turn this setting on or off.

Video Clipping Settings
Video Clipping Alerts indicate whether there is too much light in your picture.
You define what “too much light” is by selecting the allowable luma level, sample
area size and event duration in frames. The light level must exceed all three of
these thresholds. The Video Clip Alert will extend for as long as all three thresh-
olds are exceeded.

The Shot Clock
The Shot Clock’s timer and production clock capabilities enable you to time
events in hours, minutes, seconds and video frames. You can time your clips
using a drop frame rate, non-drop frame rate or a PAL rate and choose between a
12 or 24 hour clock.
Audio Clip Alerts appear as thin red
markers at the top and bottom of the
green audio wave form in your clip.
When you see an Audio Clip Alert, this
indicates that there may be a problem
with your audio. Review it and adjust
your equipment as needed.
