12 EDITING SYSTEM PHASE ADJUSTMENT

To ensure accurate, error-free editing with an AB roll editing system or any other multiple-unit system, you must adjust the phase of the built-in time base corrector (TBC) after connecting all system components. Phase adjustment must be updated each time you replace a connection cable, add or replace one of the units, or make any other changes.

●Preview switcher

Automatically switches the signal shown on the main monitor in conjunction with editing controller operation. (e.g. SW-320 from Imeginics Co., Ltd.)

●Enables editing without separate monitors for program output and pre-read output.

●When using an editing controller provided with the pre-read function, is not necessary to set menu switch No. 351 <PRE READ> on the BR-D95U to “OFF”.

Usable controller: RM-G820U

●When using the RM-G820U, check that the model name shown on its packing case ends with (A) and that (A) is indicated on the serial number plate on the controller.

●The RM-G820U is not ready for audio insert editing on CH3 and CH4. To select insertion on CH3 and CH4 with this unit, change the settings of menu switch No. 377 <AUD EDIT PRESET CH3> and No. 378 <AUD EDIT PRESET CH4>.

Notes:
• Note on the special effects generator
As most special effects generators provided with a DVE (Digital Video Effect) function have a built-in frame
memory, one frame delay occurs if the pre-read function of the BR-D95U is used. To avoid this, only use
special effects generators with no frame memory (such as JVC’s KM-3000) or ones provided with a function

that allows you to bypass the frame memory.

• When menu switch No.351 <PRE READ> is set to “VID-ON” or “AUD-ON”, the Record mode cannot be

engaged (pressing both the [REC] and [PLAY] buttons has no effect).

• When editing with the pre-read function, the material on the tape in the recorder is replaced with the special-

effects pictures. If you want to keep the original material, be sure to back up the original tape.

• When video phase shifting is obvious in video signals inserted for pre-read editing, adjust the video phase

(refer to page 120).

• If the editing controller is not provided with the pre-read function, set menu switch No. 351 <PRE READ> of

the recorder BR-D95U to “ON”.

12Send external reference sync signals from the sync signal generator to the system components. Composite video signals are delivered as video signals.

*When editing on directly connected VCRs without a switcher, adjustment of system and subcarrier phases is not necessary.
