where to obtain overlay videos with alpha layer

[perfection]

I hope this is the right sub forum to ask this question. I have created a video for my son on a videostudio timeline. I need to show shimmerring stars or a dhooting star or even fireworks or glows at various points in the film. I do know how to set the overlay trach but i would like to know of sites or purchaseable video clips like these to use in the production of video.

http://stockfootageforfree.com/free-dvds/ has a DVD full of fireworks footage. You just pay for postage. I ordered 4 different titles and received them in around a week. Very impressed.

http://www.detonationfilms.com/free_stuff.htm also have a lot of stock footage for download, some with alpha, most without. Play with the overlay mode. In most cases you won't need the alpha channel anyway.
