Key frame effects for pattern numbers 1951 to 1956 and 1961 to
1966
Normally, for DME wipe transitions with pattern numbers 1901 to 1912, at
the end point of the transition the A bus image has been completely replaced
by the B bus image. For pattern numbers 1951 to 1956 and 1961 to 1966,
however, at the end of the transition the A bus image remains within the B
bus image, rather than being completely replaced. Such effects are referred to
as "picture-in-picture".
With these effects, the transition directions are fixed as NORMAL/
REVERSE, so that in principle the first occurrence of the transition results in
a combined image including both the A bus and B bus images, and the next
transition returns to the A bus image only. (It is possible to select whether to
start with a "normal" transition or a "reverse" transition.)
Creating frame effects for pattern numbers 1951 to 1956
With pattern numbers 1951 to 1956, as the transition progresses the B bus
image gradually appears.
Create a key frame effect for the above patterns as follows.
• For the first key frame, adjust the insertion position and size for the picture-
in-picture.
• For the last key frame, use a position outside the image area, or set the size
to zero, so that the inserted picture is not visible.
