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>.

Positions indicating (A)

Upgrading is required if the RM-G820U

without (A) indication is used.

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.
