The Match Frame occurs at approximately the midtime of the scene, but may
occur earlier or later depending on the duration of the scene and the speed or
duration of the MX1 or MIXER Events.
Edit Suite will attempt to begin recording the second half of event 002 at the
exact frame where the first half of event 002 ended; however, the match frame
will only be as accurate as your VCRs and camcorders allow. If you have frame
accurate VCRs and time code, the match frame can be exact so that in your final
recording there are no missing or repeated frames around the match frame
position. If your VCR/camcorders are not frame accurate, there may be a few
frames of underlapping or overlapping video at the point of the match frame.
If your VCRs are not frame accurate, you can minimize the impact of any match
frame error by manually splitting event 002 in the preceding example into two
scenes and selecting a
match
point where there is non-critical video and a pause
in the audio.
Simultaneous Rolling of Two VCRs
You can roll two VCRs simultaneously by placing an MX1 or MIXER Event
between two Scene Events, leaving the OUT time for the second Scene Event
blank, and pressing [PREVIEW] or [SHIFT]+[AUTO REC].

Select a CUT or a high-
speed transition
The OUT time for the first event and the IN time for the second event should be
the positions where the video from the two sources needs to be synchronized. To
fine-tune the point where the "B" source starts playing, adjust the IN OFFSET for
the "B" source's VCR port as described in Chapter 7,
Fine Tuning
.
If you inadvertently fill in the OUT time for the second source, either delete the
event and create a new one or change the OUT time to a high value—like
23:00:00.00.
Setup and Precautions
Before you can perform an MX-1 transition from Edit Suite, the GPI-M parameter
in the CONFIG menu must be set to MX-1, and the MX-1 must be attached to
Edit Suite's GPI-M port. Use the GPI cable provided with Edit Suite to connect
the two devices. If a different cable is used, make sure it is a stereo cable.
