All right.
Welcome to the class introduction to 3D compositing.
So this is going to be a bit different than the last course I've taught.
So if you guys are up to speed we already know how to do 2D tracking.
We already know the basic interface of new know to do some color correction and some basic clean plating
and roto scoping.
So those are kind of the really beginner skills so you need to have that kind of knowledge before you
move into this.
If you're interested you can go back and check out that course I have on new Demi just click on my profile
you gonna find it.
And you know it's a it's an almost five hour course really in detail to try to get you up to speed.
So what we're gonna do in this course is a couple of different things but I split it up into kind of
the first lessons are all about the theory and the concepts of what we're doing and also the problem
solving skills about what we're doing.
So these are kind of the even more important than notes himself because if you don't understand how
to think you will understand how to use the notes.
So a lot of people just say you know if you go on YouTube or something you might find hey here's a camera
tracking is true but it's not gonna teach you about cameras.
It's not gonna teach you about Parallax and you know it's not gonna teach you when to use in what's
in which situations.
So this course is much more in-depth and more valuable I think.
And I hope you guys find it valuable as well.
So first we're going to start out with a planet tracking composite which is a bit easier than full on
3D tracking but it's gonna get you the concepts we're going to do.
Image integration faking reflections.
So I'll explain our next slide here if we go.
So this is Project 1.
So we see have a red truck here and you see this kind of orange grid.
So this orange grid is kind of tracking the perspective of the side of the truck.
And if we hit play here we can see exactly what this project is.
So we had this we have ice cream truck texture here that we're going to I'm going to be supplying you
guys with.
And we also have a window that has a reflection.
So if you look in the window we can actually see parallax which is movement well to the camera in there.
Some of the teaching guys how to do that with nuc expressions associated to the plane or track that
we get off the surface and then we're gonna do a bit of color integration as well just to make sure
we're matching some shadows and stuff they're being cast.
The second project is pretty in-depth.
There's a lot of I would say intermediate concepts in this in this class.
So what we're gonna be doing is removing this car from this path.
It's driving and moving it onto this beach.
So if this if you guys know if this camera wasn't moving you can probably think about logically how
you might do this you might just cut it out stick an image over the top and just move it.
That's kind of what we're doing except the camera is moving.
This is being filmed from a drone that's flying.
So as soon as you introduce camera motion into shot it becomes a bit more complicated and yeah.
So we're going to cover all those ideas so I just show you.
So we're creating a clean to kind of scrub back here.
So we're creating a clean paint plate patch.
So we're kind of painting it out and projecting it on a 3D piece of geometry and we're putting that
back over the original footage which gets rid of the car.
So you see the car is gone and then we're gonna go back to the original footage and stabilize that car
so we can track the wheels and get the transform and rotation of that car and then we're gonna move
that on the beach and reproductive on that same piece of geometry.
I was just talking about so you don't know projections are and you like what is he saying right now.
That's fine because that's exactly what is classic and teach you.
So we're gonna get you all those ideas and I think you guys will get a lot out of it.
The last project we have is a bit simpler.
So we kind of go easier and then we have the same project which is pretty in-depth.
And it might take you but you might have to go through and look at the scripts.
But this one is pretty easier again.
But it is a nodal pan so it's still a 3D track but we're replacing a sky.
So we're doing a sky replacement a key and a little bit of color correction even when the camera is
moving.
So this is good technique to know because it's very commonly used and it is different than 2D tracking
so you might be familiar with it like a 2D tracker 3D nodal pan is similar but not the same.
So I do want to throw it in at the end there.
So you guys know exactly what to use and went.
So this is just the last slide here just the difference between two and compositing in 3D compositing.
So one involves a 3D camera in the world's 3D geometry over a real scene camera projections placing
elements anywhere in the three scene or over footage.
You can have particles you can have snow and then you can also have compositing computer generated imagery
into scenes.
So like you know Transformers or avatar or something like that is going to be 3D compositing.
We're not going to go fully into CGI compositing in this course but we are doing 3D compositing which
is the fundamental I would say pillar of CGI compositing.
So you need to know these techniques before you can even touch the other stuff.
So yes.
So that's kind of the the difference there.
It's mostly the main difference is that your camera is moving.
It's not just photoshop anymore you're not just doing now still frame you know anyone can open up photoshop
and change a couple of things put a little fire or you know after effects where there's a little bit
of 2D motion and you want to stick a fire and explosion but a lot of people can't do 3D compositing
which is you know complex camera motion and projections and these ideas.
So we're gonna get into all that and yeah.
So let's jump in.
