) and i have managed to find a good sound, understand how to insert it and i thought i found a good animation aswell. but the animation was gif, with only 17 frames, and if i have understood this correctly, those frames are integrated with the ones in the clip itself, so the explosion will last less than a second. and i will get a white background to it... does anyone have any good explosion-files? 
if posible, i want a transparent background. and can you help me insert it correctly into the clip? the explosion should be able to last 2 or 3 seconds. it should also not be like atomic bomb size, more like a car blowing up or something.(i know, im wierd
)
