Breakdown

- [Instructor] So here's a little breakdown…of how this shot was created.…As we watch this, you can see that there's a couple…of different things going on.…We have a sky replacement up top.…We obviously have the building destruction here.…Underneath it you can see…that we have bits and pieces…of debris and some structure there replacing the insides…of the building and we have some fire.…And of course we have the smoke effects from the missile.…So let's go ahead take a look at the skyline.…And if I open up my comps here,…I have all these different pre-comps used…to create this.…

I started out with the city,…just isolating out the buildings and the foreground here…and eliminating the sky.…And I was able to do that using the extract effect.…So I created an extract effect…where we're able to pull all that out…based on the luminance, or the red brightness of the shot.…And then with the matte choker…we just fine-tune that just a little bit.…And from there, I fed that into another comp.…And this is the pre-comp…for the building destruction portion.…
