Snow FX tutorial. Adding digital snow using Adobe Premiere
Although this tutorial uses Adobe Premiere, the technique can be applied
to most applications. If you're not sure how to do it in your choice of
software download
the free test clip and experiment.
1. Place your background footage on
Video track 1
2.
Place a Snow FX clip on the Video 2 track. (They all loop, so copy and
paste multiple copies of it after itself for a longer sequence)
The Snow FX background is black, but we
want to see our background behind the snow.
3. Right click
on the Snow FX clip and bring up the Transparency settings (found under
the Video Options settings)
4.
Select "screen" as key type. This will cause the black portions of the
Snow FX clip to disappear, leaving us with just the white snow flakes
overlaid on the scene.
That's it!
Using this technique you can continue to modify the scene until you have
the snow performing to your liking. Add more layers of different snow,
or simply copy the one you have on top of itself to increase the
visibility of the snow. For increased density of snow, duplicate layers of
snow and offset them slightly until you have the desired look.
