So our Composite from the last movie, in other words, our combining of these two separate elements looks pretty good, but one of the things I like to do to make a composite even better is to make more common elements between the composited element. So, for example, I might want to color- tint both the smoke here and the house footage in the background, so that they kind of look like they are more from the same source. Basically, when you're compositing, the more common attributes the different components share, the more believable the composite.
Now what I could do is apply a Color Correction effect to the mushroom cloud from Detonation Films and also to the image in the background, and then adjust them both the same or copy-and-paste. But then if I want to make changes to one, it's kind of annoying. So what I'd like to do is create what's called a nested sequence. So what I'm going to do, I'm going to look at the current sequence settings. It's 1280x720 square pixels and I'm going to make another sequence that's just about that same size 720p24, the HDV preset here.
I'll call this Master Sequence and I'll go ahead and hit OK. Then I'm going to take the actual Compositing sequence, which contains both elements, the BlackMushroom01.mov and snowy neighborhood.psd layer on top of each other. I'm going to drag that into my Master Sequence. Now, when I apply a Color Correction effect, let's say, for example, Color Balance, which I really like, to this layer, which in this clip actually is a nested sequence, in other words, a sequence inside of this sequence.
Then when we apply the effect to this clip. It applies to all of the clips inside of the Sequence. So when I adjust the Color Balance, for example, go over here, and let's say, we'll make this a little bit more blue. So I'll take away cyan from the shadows, maybe cyan from the reds, maybe add a little bit of blue in the highlights, maybe a little bit of green in the midtones there. Then we have a more believable composite, because they both have kind of like this cyan tint.
So here is before and here is after. Nesting sequences like this is great when you have multiple layers stacked on top of each other, like in our original sequence here. We have multiple video tracks stacked on top of each other and you want them all to experience the same color adjustment, but I actually find I use it even more for when I have a huge timeline, let's say, for example, that music video that we've seen. If I want to color-correct the entire music video, then I'll nest that sequence and just apply one color effect to that one nested sequence.
It's just one layer, so I make one correction and it affects all clips equally. So again, it's great for compositing, but it's also great for color correction and a whole bunch of stuff, as well.
