GrainPlate function

Code:
############################################################################################
### GrainPlate 1.0: add real grains to your clip!                                        ###
###                                                                                      ###
### Usage:   GrainPlate(clip, strenght)                                                  ###
###          where strenght range goes from 0 (clip untouched) to 1 (max strenght)       ###
###                                                                                      ###
### Just add your own grain plate, there are many free to download over the web.         ###
### Hints: NEVER upscale/downscale a grain plate; choose one with the same size of your  ###
### clip, or bigger; choose only REAL film grain, and not recreated.                     ###
###                                                                                      ###

function grainplate (clip clip, "strength") {
strength = default( strength, 0.25)
grain=avisource("putyourowngrainplatefilehere.avi")\
.crop(0,0,clip.width,clip.height).loop.trim(0,clip.framecount-1)
return overlay(clip.tweak(bright=1),grain,mode="softlight",opacity=strength) }
To do: add a parameter that let you choose between several available grain plates.

Enjoy it, and Happy New Year to everyone!
