Explosions In motion

Try this:

http://www.detonationfilms.com/free_stuff.htm

Or indeed elsewhere on their site. They have a whole bunch of explosions, and lots of other stuff either free or very cheap you can use.

 

try Motion's particle emitters...

There'a a few explosions already in Motion's Pyro category. You can adjust the parameters if necessary to vary the results.

 

This is cool footage. Not sure if its possible, but I would love to use these explosions in iMovie HD with the right plug-in, say from geethree. If its not possible to use in iMovie, then how about in Final Cut Express?

Thanks

 

Final Cut Express you certainly can - It supports compositing of multi video layers. I doubt you could make it work in iMovie regardless of what plug ins you have as it only supports a single video track.
