Table DESCRIPTION
#
LANC
LANC tables 001, 002, 007, and 012 are the primary tables for VCRs and Camcorders
using LANC protocol. (Read the RCTC comments for tables 121-126 below.)
• Table 001 works for most full-featured VCRs with jog and shuttle capabilities.
• Table 002 works for most camcorders and VCRs that do not have reverse
jog/shuttle capabilities (review or reverse play only).
• Table 007 is for VCRs/Camcorders—like the CCD-V5000—that need continuous
commands sent to them to stay in Cue and Review.
• Table 012 is for VCRs/Camcorders—like the Canon UCS-1—that need waiting
periods added between each command sent to them.
The other tables in the LANC group change the performance of the jog/shuttle.
For VCRs and camcorders that do not have Time Code, select TCSRC=INT and
TC=NONE. If RCTC is used, select TCSRC=INT and TC=RCTC. If VITC or LTC time
code is striped on the tapes, 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, select
TCSRC=EXT and TC=VITC or LTC.
If RCTC is used, be sure the tape is striped. You can stripe a source tape by fully
rewinding the tape then using the Play-Write or Record-Write function. Check your
VCR manual for details.
For RCTC, if the time code counter on the VCR/camcorder goes blank or skips when
in Rewind or Fast Forward, instead of selecting the primary tables, use tables 121 -
126. Many VCRs with RCTC do not update the time code when the VCR is in Rewind
and/or Fast Forward mode. Since Edit Suite needs this information during searches
and auto-records, the rewind and fast forward commands have been changed to fast
play (cue) and fast reverse play (review) commands. This way Edit Suite is able to
keep track of the time code. With tables 121-126, pressing the FFWD and REWIND
transport keys will do cues and reviews only.
001
Full-featured table: Works with most LANC VCRs that have forward and reverse
jog/shuttle capabilities and two or more speeds between pause and play and between
pause and reverse play. Edit Suite provides two speeds between pause and play and
two speeds between pause and reverse play.
For VCRs with jog capabilities, each slow turn of the jog advances/rewinds the video
approximately three frames. Faster turns increase the speed up to a maximum of play
speed.
121 Same as LANC- 001, except for VCRs and camcorders using RCTC if the VCR counter
goes blank or skips time during Rewind or Fast Forward. (Edit Suite will show
asterisks in the time code field if it cannot read the counter/time code information.)
111 Same as LANC-001, except each slow turn of the jog advances/rewinds the video
approximately five frames.
112 Same as LANC-001, except each slow turn of the jog advances/rewinds the video
approximately 15 frames.
126 Same as LANC-111, except for VCRs and camcorders using RCTC if the VCR counter
goes blank or skips time during Rewind or Fast Forward. (Edit Suite will show
asterisks in the time code field if it cannot read the counter/time code information.)
