The 300 Clip Instant Access System consists of the ST300-SSM VTR Controller, STS420
Shotbox and Shotlist Software.
The ST300 controls up to 3 video channels individually or ganged.
SHOTLIST provides fast access to existing video clips stored on Grass Valley Group’s PROFILE,
other DDR, VDR or Video Server supporting Louth Protocol.
The SHOTLIST contains up to 300 CLIP IDs, stored in non-volatile memory in the ST300.
Any clip in the SHOTLIST can be quickly loaded by simply entering the associated 3-digit
number of its location, then pressing [LOAD]. Press [PLAY] to play the clip.
Press [RECUE] to recue to the beginning of the clip or to the “recalled” time if defined.
Upon receipt of the Learn command, the ST300 saves the CLIP IDs of the currently loaded clips,
the current time of each clip, the VTRs they are loaded on and the current GANG mode into the
appropriate Cue Point.
When the RECALL command is received, the ST300 loads the learned Clips onto the learned
VTRs, cues the Clips to the learned time and restores the learned GANG mode.
Learn & Recall may also be done directly from the ST300.
