Google Earth Studio – Camera Target & Multi-View


Hello, I’m Jon, and
welcome to another tutorial in our “Getting Started
with Earth Studio” series. In this tutorial, we’ll be covering two
powerful features in Earth Studio: camera target and multi-view. So as always, to get started
I’ll make a new blank project – I’ll call it “Camera Target” – and I’m going to
navigate to Philadelphia, because they have really beautiful
3D imagery, especially downtown. And I’m going to just position my camera so that it’s more or less
facing Logan Circle right here, and I’ll make my first Camera Target. And this is really simple to do; I can
just right-click anywhere on the screen and select “Set Camera
Target” from the menu. And so a lot changes here. We have our camera view here
on the right, that we’re used to, but we also have this new view,
and that’s our top-down view. And this is super handy, because
it gives us a bird’s-eye perspective of our entire animation. We see our Camera Target represented
as this little target icon right here, and we see our camera represented –
both its position and orientation – as this pyramid shape right here. And this is just standard Google Maps,
so if we scroll in and out we can zoom and we can click and drag
to reposition the map. And the nice thing about this is
that everything is dynamically linked between the top view
and the camera view, so if I were to come here and drag my
camera, you’ll see that it locks right on to this new Camera Target and everything updates in real time. So it’s a really fluid way of
re-positioning your shot. So I can also move my Camera Target
around right here in the top-down view. And you’ll see that when I do that, there’s this red circle here where
my Camera Target used to be. And this is because there’s a keyframe set
there when I first set the Camera Target, and that shows up
in our attributes list under this new group
called “Camera Target”. And it has a longitude, latitude
and altitude with keyframes set, just like our camera position. There’s also this Influence,
attribute, that we’ll cover later. And because our Camera Target is
an attribute that appears in the timeline, it means that it can also
be added or removed through the “Add Attributes” menu
above the attribute list in the timeline. If we click here, we’ll see that we
have this Camera Target at the top, and right now it’s active, it’s green, we
can also turn it off and turn it back on very simply – and when we turn
it on from the attributes menu, it’ll just put our camera
target at whatever is directly in the centre of our screen. So for now, we have this
Camera Target, its position is set, and if we move our target off the
keyframe and move our playhead, it snaps the value back
to the saved value, and the same thing
applies with position – this is basically just like it
works in normal animation. If a keyframe is set and we make
changes but don’t keyframe them, they won’t be saved. So with that in mind, we’re
going to go to the last frame. We’re going to move our Camera Target
so that we’re looking right over here at the Philadelphia Museum
of Art (I believe is the name), and I’m going to set a camera
target keyframe at the bottom here and I’m gonna do the same
thing with our camera position facing right around here – keyframe – and now you’ll see that we have
these lines drawn between our keyframes, and this is basically the exact path
that our target and camera will follow as they move between the
two keyframes that we’ve set. We can edit this path by
dragging these keyframes, and that will actually
update the value live, so now these keyframes have new
values as we move them around. I’ll undo that. We can also move our camera here and set
a new keyframe and our path will update. So right now, we have this kind of nice view as
we’re travelling past Logan Circle along this road right to the
Philadelphia Art Museum, but let’s say around
halfway here we want to – not really want to be so close to the
road, we want to have more of a bird’s-eye view of the
city, more of a macro view. And to do that, we’re just
going to drag our camera out here, and we’re gonna create a new keyframe. And when we do that, Earth Studio
automatically smooths our path, so that as we go through this keyframe, instead of being a harsh
angle it’s a nice smooth curve. And we’ll see that we have these
Bézier handles here, these easing handles, that allow us to adjust
the shape of this path. So if I click and drag these, we’ll
see that our path updates. And if we right-click on this,
we’ll see that we have some options; we have smooth path, and this is
our default auto-smooth algorithm, and it basically just finds the perfect
tangent for longitude and latitude to give us a nice smooth curve. We also have an option to make linear,
which will get rid of any easing handles in the Top View. And if we command-click, we can
toggle between smooth and linear. And we can also unlink these handles
if we want to have direct control over one half of the keyframe. So very cool here. A few more things to cover, one of which is the other
multi-view angles up here. In addition to the Top View we have
a North, South, East and West view and these are just side views in
each of the cardinal directions. So this is facing North – we can see and edit our animation from
a side view, which can be really useful. We also have this “Influence” attribute under
“Camera Target” that we mentioned earlier, and this is an extremely powerful tool. You might have noticed while we’ve been
animating that this yellow caution sign has shown up next to
our “Camera Rotation,” and that’s because by the
nature of Camera Target, we’re overriding our Pan
and Tilt attribute values because we have to set those
appropriately so that our camera is always facing the target. But if we were to set our influence to 0,
we’ll see that the caution sign is gone, and that’s because whatever
our values are here are now taking priority. Now our camera is totally
ignoring the Camera Target and just going on its merry way depending on whatever the pan
and tilt keyframes are set to. And we can do some
pretty cool features with this. So for example, we moved our
pan here so that we’re facing kind of along our path, and if we come out here to frame 240 or so and we set our influence back to 100, we’ll see that now our
camera is facing the target again. And as we scrub back in time, we’ll see that Earth Studio is
merging those values together, it’s blending them so that
as we go along the animation we’re slowly pointing
directly at our target. And if we ease this a lot, we can get a really smooth effect where
our camera is kind of flying along its way and then it slowly moves back
to face our Camera Target. So that’s all for now in this
Camera Target and multi-view tutorial. As always, please check
up on the documentation to see some more detailed information and some other tips and tricks
about working with these tools. Until next time. Thanks a lot for watching – bye!
