you can record a color bar signal from a signal generator in the joints between the scenes of a finished tape.

To carry out standalone editing

Set the edit IN point with neither the recorder nor player selected with F6 (R/P SEL).

F1 (AUTOEDIT) flashes, and it is now possible to carry out automatic editing.

If necessary, you can also set the OUT point in advance.

5-3-4 Preread Editing

Video and digital audio signals already recorded on the tape can be used as an edit source for insert editing. This type of editing is called “preread editing”, and this unit uses the preread heads to read the signals in advance from the tape.

The read signals can be sent to a mixer for mixing, and can be recorded either on the original channels or on other digital audio channels.

For preread editing, set F3 (PREREAD) to “ON” in function menu page P04: MISC-1 (see page 67).

PROC and set setup menu item 309 to “AUTO1” (see page 84) so as to use an external reference signal.

•When the preread mode is selected, to prevent feedback due to the loop connection, no E-E video is output in any editing mode of this unit, however, if the loop connection remains and an E-E signal is output, feedback will occur.

To prevent this, select PB mode for the video and digital audio channels in all editing modes before the preread editing, as follows.

1 In function menu page P01: HOME, set F6 (PB/EE) to “PB”.

2 In function menu page P04: MISC-1, set F3 (PREREAD) to “ON”.

3 Make the necessary connections for the preread editing.

4 After selecting the desired insert edit mode, carry out the preread editing.

5 When the preread editing is completed, remove the connections.

6 Set the F3 (PREREAD) to “OFF”.

7 Check that no loop connection remains.

Notes

•In preread editing, if an input video signal is used as the reference signal, a loop connection between video input and output on this unit may cause acoustic feedback (howling). To prevent this, set F2 (REF VID) (see page 66) to “REF” in function menu page P03: VID
