MX1 Events
MX1 Events are available to Videonics MX-1 users only. MX1 Events are used to
create A/B Rolls between scenes from two play VCRs or AXA Rolls between
scenes from the same VCR. In an A/B Roll, instead of cutting from one scene to
the next, a fade, wipe, dissolve or other special effect can be used. During the
transition from one source to the next, both sources are played, displayed and
recorded simultaneously.
To specify an AXA Roll, add an MX1 Event between two scenes from the same
VCR. Because both scenes are from the same VCR, a video freeze is done at the
OUT point of the first scene, and the transition to the second scene begins from
the frozen scene.

A/B Roll
To specify an A/B Roll, add an MX1 Event between two Scene Events from
different VCRs. In the above example, scene 002 is from VCR A and scene 003 is
from VCR B.
The arrows on events 002 and 003 indicate that the events are part of a logical
group. In this case, the group is the scene from event 002, the MX-1 transition,
and the scene from event 003.
In the MX1 Event above, the event number—002/003—reflects the event
numbers of both sources in the AXA and A/B Rolls. FX is the MX-1 transition
number, DI is the direction for the transition, SP is the transition speed, BG is the
background color, and BC is the border color. A blank for a border color
indicates that a border color is not used.
When the above sequence is previewed or auto-recorded, Edit Suite sends
commands to the MX-1 to tell it which source to make
current
and which to make
next
, and then sends all the transition information.
For A/B Rolls, the transition will be timed so that the midpoint of the transition
is the OUT point for the "A" source and the IN point for the "B" source. You can
adjust where the "B" source in an A/B Roll begins by changing the IN OFFSET
parameter for the associated play VCR. Refer to Chapter 7,
Fine Tuning
, for more
information.
For an AXA Roll, the only setup difference is that you place the MX1 Event
between two scenes from the same source. For transition timing, the start point
