Hello everybody,
I think i will join this challenge. It looks like a funny project. Iīve picked one of the videos and try to give my best. There are so much ideas in my head. First i want to break open the street and let some eruptions come out of the hole. Maybe i let some rocks fly into a building with some nice explosions, or let the Bus explode after a clash with a big hot rock.
Here are my first wips. Still no lighting or color correction. Just a test how the street reacts.

Greetings and good luck to everybody,
Andreas

Hi,
here is what i have done during the last days. I replaced the bus of the video with my CG-model and let it crash after an impact. The background behind the city is currently a still image. I want to replace it later and add a pyroclastic cloud wich rolls through the city.

Here is an animation in "divx" and "mov" format:

1.6 MB divx (http://www.visiongraphics.de/fxwars/fxwars06.avi)
2.3 MB mov (http://www.visiongraphics.de/fxwars/fxwars06.mov)

This is a preview from the end of the scene. I know, the movement of the bus needs some tweaking.
comments are welcome.

Greetings, Andreas

Hey. Looking nice. I was about to comment on the movement of the bus, but I guess you're already dealing with that.
The only other part that feels off would be that building in the back. Feels too bright.

Keep it up. :)

Thanks Vormav,
you are right about the bright building. Funny, my girlfriend said the same to me yesterday. I think sometimes i should listen to her.

Looking really good. My only comment is that the ash falling looks slightly out of place as it seems to turb around too slowly. It seems to float. Keep up the good work.

Hello everybody,
here is another update. I replaced the still image in the background against an animated particle-simulation. Iīve seen the videos of some exploding vulcanos and saw that there isnīt just an ashcloud thatīs rising in the sky. The cloud itself makes turbulent rotating movements. So i made a particle simulation and connected the particles to a fluid shader. Then i could drive the rotation with the texture of the fluid.
Even if the movement is not correct, there is no time for corrections. The rendering of the ashcloud took about 3-4 days, and there is only one week until the contest is over. Currently iīm trying to make a pyroclastic flow for the end of the sequence and some more impacts.
Hope i can finish this.

Hi, here is my final entry for this contest.
I used one of the videos from Roberto Ortiz. First i had to stabilize the footage, then i removed the background, some moving parts wich i donīt needed and two humans who walked along the sidewalk.
The street is CG. In the first few seconds comes a crack in the ground, smoke and a lavaeruption comes out. At the end of the footage i replaced the real bus against a CG-model. Then i could make a collision and an explosion. The ashcloud for the volcano in the background took the longest time. For this i used particles with a fluid shader. The volumetric effect takes a very long time to render. Thats the reason why i had to give up my idea for a pyroclastic flow through the city. Everything was made using Maya, except the explosion after the collision with the bus. For this i used particle illusion. I used After Effects for compositing and color correction. At the end i had a little time to add some sound. It took about 5 weeks in my freetime to finish this. The length of the video is 18 seconds.
So now have fun and enjoy the video.

Nice. The scratchy tv screen effect was a nice finishing touch. I feel almost like it could benefit from having a record button blinking somewhere to accompany the effect though. ;)
Good job with the color correction, too. Everything seems to fit in really well.
