Roll and Trim controls
Pre-roll
How many seconds the deck should allow the tape to roll before capture/layoff
starts.
When capturing or laying off the deck will cue to the VTR in point minus the
value set in the pre-roll field. No actual capture/layoff takes place during a
post-roll.
Post-roll
How many seconds the deck should allow the tape to roll for after capture/
layoff ends. No actual capture/layoff takes place during a post-roll.
Video Trim
This numeric entry field / slider allows you to correct timecode offset errors
that might occur when capturing or laying off video.
The Video Trim controls which frame of video is recorded at the edit (in) point
and can be used to help fix video routing or system delays.
Edit Trim
VTR Output module only.
Similar to video trim, it allows you to correct any timecode errors causing the
recorded material on tape to be starting at the wrong timecode.
The difference between video trim and edit trim is that the video trim setting
will make adjustments to the time when the frames start being sent from disk
to tape, i.e. when layoff starts, whilst the edit trim setting makes adjustments
to when the deck actually starts recording.
The point at which the deck actually starts recording prior to receiving the
video is what can be adjusted using the edit trim control, should you find that
the layoff is not ending up at the correct timecode.
