Note
Cross-fade, fade in, or fade out processing is applied to the recordings after the IN or
OUT point. Setting this item allows rewrite of the recordings after the OUT point. Even
when the minimum value (5ms) is selected, one-field recordings are rewritten.
To avoid rewrite, select CUT in menu item 317. However, the audio signals discontinue
at edit points. (There is no effect on the recordings of the video signal.)
805 AUDIO MONITOR
OUTPUT MIXING Select the audio mixing method used for digital audio signals and Betacam playback
analog audio signals supplied to the MONITOR OUTPUT connector.
ADD: Simple addition.
RMS : Root-mean-square.
AVE: Simple average.
807 AUDIO OUTPUT
PHASE Select the output timing of a digital audio playback signal (SDI only). The reference
position corresponds to a setting of 80H; when the setting is less than 80H, the output
timing is advanced, and when it is higher than 80H, the output timing is delayed. (80H,
128 samples=approx. 2.7 ms, 1 sample=approx. 20 µs)
0... 80 ...FF: Setting in this range
810 AUDIO EDIT
PREVIEW
SWITCHER
Set the output phase for the audio playback signal when any of the ASSEMBLE,
VIDEO, A-CH-1 to A-CH-4, and TC is set t ON in the Edit Preset menu.
INT : The audio playback signal output phase is the same as the output phase in the
E-E mode. Use this setting when editing with a single VTR, or when previewing while
watching the VTR output signal.
EXT: The audio playback signal output phase is the same as the phase of an input
video signal or external reference video signal.
Note
Whichever setting is used, the correct editing results will be obtained. When, however,
you are using an external switcher to switch the audio output signal from this unit for
the purposes of preview, selecting EXT will prevent any muting or discontinuities in the
audio at editing IN and OUT points.
