Ripple

The transition from Clip A to Clip B occurs through Ripple. A frame ripple grows full frame starting at specified origin, greys, dissolves into grey B frame ripple, regains color and subsides revealing B frame. Alternately in emerge option From within A frame fully grown ripple, B frame ripple grows and after full growth subsides revealing B frame.

## trans.Ripple(clip, clipb clip[, float overlap = 1.0 ][, int origin = 0][,int amp = 4][, int wlength = 40][,int merge = 0] )

Parameter description:
clip : A clip. Constant format with sufficient dimensions
clipb : B clip. Must have identical format of A clip
overlap : transition time length in seconds. Floating point. Must correspond to at least 8 frames.2.0 sec or more recommended
origin : Ripple center location. 0 to 8. 0: center of frame 1:N through 8 : NW.
amp: amplitude of wave. 1 to 5.
wlength : wave length 4 to 1/8th frae diagonal
merge: ripples merge during transition or not 1 or 0
