Panasonic Hi-Fi Professional/Industrial Video DS850 - Manuel (Page 35)

Precautions for editing
If the EDIT START button is pressed without the editing mode having been set, the edit mode buttons
(ASSEMBLE, VIDEO Hi-Fi, AUDIO CH1, AUDIO CH2) flash 6 times to prompt the operator to select the mode.
Due to the preroll requirements, a pre-recorded section lasting at least 3 seconds must precede the edit start
point. Editing cannot be conducted from the very start of the tape.
Normally, the controller’s preroll time is set to 5 or more seconds. However, when phase-synchronized editing is
not to be performed, editing is possible with a 3-second preroll time by using an external sync signal (EXT).
Precaution for assemble editing
Bear in mind that about 2 seconds of the original recording after the edit end point will be erased.
Precautions for insert editing
The picture will be thrown into disarray at the edit start and end points if insert editing is conducted using the
VHS system on a tape which has been recorded using the S-VHS system.
Since the control signal is used for the editing, make sure that the edit period does not extend beyond the
recording made on the tape.
Precautions for EE picture
NON V-FLOAT: The positions of the external sync signal and EE picture’s V-SYNC signal tally. The video
start line is delayed by an amount equivalent to the time taken by the Time Base Corrector
and other processing.
The positions of the external sync signal and EE picture's V-SYNC signal do not tally but the
proper relationship between the video start line and V-SYNC signal is maintained.
V-FLOAT:
At the V-FLOAT position, the EE picture may move slightly in the perpendicular direction.
