DFS-700/700P

Control From the BVE-900/2000 Series

Notes on Operation

Editing point delay

Because the DFS-700/700P has a built-in frame synchronizer, output of player VCR edit points set on the BVE-900/910/2000 is delayed by 1 frame, so that recording begins with the previous frame. However, recorder edit points are not delayed.

Example: If the IN point of the player VCR is set to 00:00:10:15, recording begins from 00:00:10:14.

If you are using a BVE-2000 with a ROM version of 2.00 or higher, in SYSTEM SETUP mode under SYSTEM CONFIGURATION you can set the DIGITAL EFFECT DELAY item to 01 so that the BVE-2000 compensates for the delay automatically.

Executing effects in the reverse direction

		• To execute an effect in the reverse direction from the BVE-900/910, add
		3000 to the DFS-700/700P effect pattern number. However, add 500 to
		the pattern numbers of user program effects (pattern numbers 9000 and
		above).
		Examples:
		To execute effect 25 in the reverse direction, specify pattern number
		3025.
		To execute effect 9203 in the reverse direction, specify pattern number
		9703.
		• To execute an effect in the reverse direction from the BVE-2000, add a
		minus sign (–) before the DFS-700/700P pattern number.
Chapter		Example:
		number –25.
		To execute effect 25 in the reverse direction, specify effect pattern

Control Using GPI Signals

You can combine the DFS-700/700P with any editing control unit capable of GPI signal output to carry out A/B roll editing using two players and one recorder.

You can use one GPI signal to execute DFS-700/700P effects, and a second GPI signal to turn the downstream key function on and off.

Preparations

Make the following preparations to control the DFS-700/700P using GPI signals output by the editing control unit.

For details about operation, refer to the manuals supplied with your editing control unit.

On the DFS-700/700P

• In page 1 of the setup menu, set F3(PORTS) to “GPI”.

• Press the EDITOR button on the control panel, turning it on. (This button is lit when the DFS-700/700P is powered on.)

On the recorder VCR

• Set the recorder VCR so that it enters PB (playback) mode when stopped. (If the VCR has a selector for PB or PB/EE, set it to PB.)

• If the VCR has a built-in TBC, set the VCR to DELAYED SYNC mode.

On the editing control unit

• Set the GPI signal output timing to 3 frames before the IN point.

• Set the GPI signal pulse length to at least 1 frame.

Notes

• To display the background image during or after a transition, press an

appropriate BACKGROUND bus button on the DFS-700/700P.	Chapter
