4-1-3 Making Video Input Settings Selecting the input video signal Displaying and adjusting the video input levels It is possible to check the video input levels, using the level meters. 1 • To select serial digital video and audio signals input to the SDI IN connector, select the right position (SDI IN). The SDI format includes audio signals, but there is a setup menu operation to determine whether to use these as the audio input, or to use separate analog inputs.
4-1 Preparations for Recording • When the input signal is component video, the meters indicate the Y, R-Y, and B-Y levels. The maximum values for R-Y and B-Y correspond to a 75 % color bar signal. R-Y B-Y Chapter 4 Recording • When the input signal is analog composite video, the meter indicates the sync signal level. VIDEO IN • When the input signal is digital in SDI format, the display indicates whether or not a signal is present.
4-1-4 Making Audio Input Settings Selecting the input audio signals Select the input audio signals as follows: When the video input is digital When the video input signal is digital in SDI format, it is possible to select in a setup menu whether to use the audio signals included in the SDI signal, or analog signals input to the AUDIO IN or CAMERA connectors. The settings for channels 1 and 2 and for channels 3 and 4 are independent.
4-1 Preparations for Recording 3 4 If the display is not showing the audio level meters, press the DISPLAY button in the adjustment controls until the audio level meters appear. 5 Pressing the DISPLAY button cycles the display through the audio level meters, video level meters, and setup menus. If the display is showing the video level meters or setup menus, and five minutes elapse without an operation, the display automatically reverts to the audio level meters.
4-1-5 Selecting the Monitoring Mode for Recording This selection determines the way in which monitoring will be carried out during recording. 4-1-6 Setting Time Values This section describes how to set user bit values, time code values and the real time. Open the lid covering the time code setting controls as shown in the following figure. CONFI switch Pull the projecting lug forward. Use the CONFI switch on the connector panel to select the monitored signal.
4-1 Preparations for Recording 4 Use the SHIFT button and ADVANCE button to set the user bit value. SHIFT button: Cycles through the digits, flashing the digit to be changed. ADVANCE button: Increments the value of the flashing digit. 4 Hexadecimal digits A to F appear in the sevensegment display as follows: Digit Display 5 A A B b C C D d E E F F Set the F-RUN/R-RUN switch to F-RUN or RRUN.
Recording VITC 1 Set the VITC switches in the time code setting controls to select the lines in which the VITC is inserted. Insert the tip of a fine screwdriver into the arrowshaped slot to turn the switch to the required hexadecimal digit (see table on next page). You can select the two lines where the time code is to be inserted with the A and B switches. F012 F012 VITC 3456 A 3456 Set the F-RUN/R-RUN switch to F-RUN or RRUN.
4-1 Preparations for Recording The relationship between the switch position and the line represented is shown in the following table. The factory default positions are 6 and 8 (for NTSC) and C and E (for PAL) for switches A and B respectively. Switch position VITC insertion line No.
4-1-7 Locking the Time Code Generator to an External Signal It is possible to lock this unit to an external time code generator, or alternatively to lock an external device to the time code generator in this unit. Locking this unit to an external time code 1 2 For an explanation of the color frame lock, see the footnote on page 2-4. Locking the user bit value to an external signal Turn the POWER switch off.
4-1 Preparations for Recording Then set the first DVW-250/250P so that it outputs the time code generator signal from the TC OUT connector. For example, when the “TC OUT” item is set to “AUTO” (see previous page), the unit must be in the E-E mode. Time Code Locking of Two or More DVW250/250P Units Connect the DVW-250/250P units as shown in the figure below. In this case, on each of the DVW-250/250P units, set the F-RUN/R-RUN switch to F-RUN and the CONFI switch to ECC or OFF.
4-2 Procedures for Recording This section describes how to prevent inadvertent operations during recording, and how to carry out the actual recording. 4-2-1 Preventing Inadvertent Operations During Recording KEY INHI switch 4-2-2 Recording Video and Audio The recording procedure depends on whether or not the CAMERA connector was selected in the procedure described in the section “Selecting the input video signal” (page 4-3).
