INSTALLATION
The video output from the telecine should be connected to the GEN VIDEO
IN Loop even if the VITC generator is not being used. (See Section 2.6)
Program video with VITC is available on 2 identical video outputs. The
VITC1 and VITC2 LINES items on the TIMECODE menu are used to select
the lines you wish to record VITC on.
configured using K
When using the VITC output of the 4025TR, the time code generator built into
the VTR should be set to the "EXTERNAL DIRECT" mode of operation, or
turned off completely. The VTR's time code generator does not understand
the counting sequences of the encoded KeyKode data, and will introduce
delays and possibly errors in the user bit data if it attempts to regenerate the
timecode before recording it on tape. (See section 3.9.1)
2.7.2
Connecting the VITC Generator – Digital Video
The 4025TR can be used in conjunction with the 8025 Digital VITC inserter
to generate VITC directly into the digital VITC bitstream. The following
procedure can be used to connect the 8025 VITC inserter in most
applications.
Connect the digital video output from the telecine to the digital video input
of the 8025. Connect the digital video output of the 8025 to the video input
of your digital video recorder. For VITC to be correctly inserted into the
digital bitstream, it is imperative that the 4025TR and 8025 be operated
from a common timing reference. The REF SYNC OUT connector on the
8025 provides a composite sync output that is in time with the digital video.
Connect this output to the GEN VIDEO IN loop on the 4025TR and provide
a termination on the loop. The reference sync with VITC is available on the
2 video outputs. Connect one of these outputs to the Key FILL 2 input on
the 8025. Provide a termination on the KEY CTRL 2 input of the 8025.
The Ctl Level setting on the Engineering menu of the 8025 should be set to
Video in this application.
2.7.3
Connecting the LTC Generator
The generator LTC output is available on an XLR connector at the rear
panel. The output level of the generator is factory set to 1 volt peak to
peak, but may be adjusted using the level adjustment (labelled VR3)
located near the rear of the 651 (center) module, on the bottom circuit card.
