DESCRIPTION
RS-422
Table 001 is the primary table for RS-422. It works for most VCRs and camcorders
using RS-422 protocol. The other tables in the group change the performance of the
jog and/or shuttle.
If the VCR has a step/linear choice for the jog or shuttle, select step.
Most RS-422 VCRs send time code or counter information over the Edit Control cable,
so set the TCSRC configuration parameter to INT. Set the TC parameter to the type of
time code sent by the VCR. If the VCR can send different types of time code, be sure
the time code you select in Edit Suite is the same type that will be sent by the VCR.
Some RS-422 VCRs have Real Time Counters only. If you have a VCR like this but
also have VITC or LTC striped on your tape, change the TCSRC to EXT and use table
021. The time code must be delivered to Edit Suite via an audio (LTC) or video (VITC)
cable attached to the Time Code IN port. In this case, change TCSRC to EXT and
change TC to VITC or LTC.
001
Works with most VCRs using RS-422 protocol, and includes shuttle speed down to
1/30 x Play. Turning the jog slowly advances/rewinds the video approximately 3
frames per revolution.
002 Same as 422-001, except this table supports shuttle speeds down to 1/10 x Play.
003 Same as 422-002 but the jog stays in jog mode instead of stepping up to Play speed.
004 Same as 422-002, but turning the jog slowly advances/rewinds the video
approximately 5 frames per revolution.
005 Same as 422-002, but turning the jog slowly advances/rewinds the video
approximately 7 1/2 frames per revolution.
011 Same as 422-001, but with different steps for the jog between Jog and Play.
021 This table is normally used only if LTC or VITC time code will be sent to Edit Suite via
the Time Code In ports instead of over the Edit Control cable.
If this table is used, Edit Suite will control the search process (whereas with other 422
tables, the VCR controls the search). Because of this, you may need to adjust the
INPUT OFFSET parameter during the Fine Tuning process. See Chapter 7,
Fine
Tuning
, for the procedure to use. Also, change the FFD Advanced Parameter to 00:45.
