Snow

The call script is :-

vfx.Snow(clip [,int sf = 0][,int ef = end frame][, int density = 50][, int drift = 50][, int fall = 20 ][,int big = 1])

clip: input clip of constant format. Compat input not accepted.
sf: Effect Start Frame Number
ef: Effect End Frame Number
density: %age of density of snow flakes per some arbitrary area
drift: %age of drift from vertical during fall of flakes due to air currents. Arbitrary maximum.
fall: %age of velocity of fall of an arbitrary maximum..
big: If set to 0 small size of flakes. Otherwise larger size and some crystal shape can be seen.

This function creates free falling snow flakes
