or use particles,

perhaps using trapcode= particular or stardust plugins.

hello,
try card dance effect,
expressions would be= too slow.

Should be easy enough to set up in 3= steps, below is some pseudo code.

Loop through every pi= xel=C2=A0
{
Use the sampleImage expression to sample th= e color of the pixel
Convert the RGB to HSV
Use the V v= alue (luminance) as a multiplier for the position
}
This might be a very slow way to do things as it will sample th= e image on every frame, maybe there is a more efficient way to do it,

Any i= deas or scripts that may do this?
