Grass Valley Aurora Edit LD v.7.0 - Manual (Page 117)

Dissolves
A dissolve fades the existing image as the new image becomes visible in its place.
You cannot specify the direction or kind of dissolve.
You can create fades using the dissolve transition--to gradually fade the video in, place
a dissolve transition at the beginning of a sequence; o fade the video off the screen,
place a dissolve transition at the end of the sequence.
Wipes
A wipe moves a new image over an old image. SMPTE wipes are industry standard
wipe patterns, and include more complex directional wipes, shape wipes, clock wipes,
and matrix wipes.
