We've imported quite a few renders to build up the debris along the walls.…We can now work with a different style of footage for the…debris, and that's video that was…shot with miniature debris and miniature rubble.…Before we get to that, though, I wanted to talk about speed.…So far, we've sped up some of the footage we've…brought in and left other footage at its original frame rate.…The reason for that was to try to make all…the debris consistent in speed as it flies through the air.…Now,…whenever is large, has a lot of mass, it's fallen a great…distance, or traveling a great distance through the air, it moves more slowly.…
As compared to something very small with almost no mass and therefore,…almost no air resistance, like grains of sand falling on a table top.…Hence, a lot of times, when people…shoot miniatures for special effects, like miniature explosions.…And ensure water and so on.…They'll shoot in slow motion, with the goal of making…it look larger. Now, a CG, it's a bit tricky.…You have to figure out how to make the simulation…
