Here are some numbers. 6000 frames per second. 1/10,000 shutter, 90,000 watts of light. What's that spell? The most fun we've had on a shoot in a long time. We actually had 2 ghettoblasters, 3 TV's, 3 cameras, and 3 prop phones that were 300% of original size. When buying the TV's we had the best excuse ever to turning down the extended warrenty.
My brother has been working on a way to make large explosions without the inherit danger of real explosives. Sawdust ignites well when mixed with the right ratio of air, so he devised this contraption. I hope to have an example of this at night- which is a truly spectacular effect! The intent of this is for special effects in a low-budget war film I'm scheming to start soon... err, someday.
Update: This video is featured in the MythBusters' "Viral Videos" episode, aired on Sept. 3, '08.
This should be a meteor impact, even if probably a meteor would produce a bigger shockwave :)
The explosion of the ground is accurately directed such the shape, timing, and colours. many things happens in those frames.
There are some small fixes to do, and I'm not totally satisfied with the trail of the meteor, I can't figure out a way to give it a "rest" position and slightly deform the texture as the smoke moves away.
I hope you like it!
edit: I reuploaded the video with a more convincing meteor trail and a subtle lens flare effect
